ESONET Demonstration Missions
1st Periodic Activity Report
The Periodic Activity Report contains an overview of the activities carried out during
the reporting period, describes the progress in relation to the project objectives, the
progress towards the milestones and deliverables set for the period, and any
problems encountered and corrective actions taken.
This document has to be filled in with reference to the DM Implementation plan. This
means that Deliverables, Milestones and WPs have to be the same as in the DM
Implementation plan.
The Periodic Report contains 2 parts:
- Part I: it is addressed to the coordinator with minimum input from the partners
- Part II: it is addressed to each WP Leader and reports a detailed update of each
WP activity at task level.
The report includes a rough justification of the costs incurred and of the resources
deployed by each contractor linking them to activities implemented and justifying their
necessity.
Finally the report contains information on use and dissemination activities.
Reporting period:
30 September 2008

Part I (to be filled by the DM coordinator)
In January 2008, the MoMARSAT cruise proposal, core of the MoMAR-D project, was
submitted to the French Fleet Committee. After evaluation, the cruise has been prescheduled
for the summer 2010. The activity of the MoMAR-D DM was then postponed to cope with
this new schedule. The MoMAR-D project actually started in September 2008. This first
report does not contain the part II and only presents the updated schedule.

Executive summary
The MoMAR (Monitoring the Mid Atlantic Ridge) initiative aims at providing
multidisciplinary time-series data set for hydrothermal systems in the Azores region of the
Mid-Atlantic Ridge. This coordinated plan aims at determining the feed-backs between
volcanism, deformation, seismicity, and hydrothermalism, and to understand how
hydrothermal ecosystems couple with these sub-surface processes, and how this affects
exchanges with the ocean.
Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK
(geodesy), and BBMoMAR (sismology and MT) experiments and will be further
implemented in 2008 with the deployment of autonomous temperature probes at selected
vents. MoMARSAT will maintain and reinforce these experiments, with a stronger
participation of colleagues from other European countries. MoMARSAT is the cruise
proposal to implement the MoMAR-D project.
We will use the SEAMON technology developed during the ASSEM EC project, with two
nodes acoustically linked to a surface buoy that will ensure satellite communication to a land
base station. The system will comprise 2 scientific nodes: a geophysical node moored in the
Lucky Strike lava lake, and a geochemical/ecological node at the Eiffel Tower vent site. This
observatory infrastructure will acquire a synchronized multidisciplinary data set, and allow us
to develop solutions for sensor interoperability, shore-sensor interactive communication, data
management and dissemination, and public outreach.
MoMARSAT comprises two multidisciplinary ROV cruises, the first one is prescheduled in
2010 to deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike
vent field and the second one in 2010 to recover it. The study area belongs to the Portuguese
ZEE and is part of a planned OSPAR “Marine Protected Area”.

Executive summary
The MoMAR (Monitoring the Mid-Atlantic Ridge) project was initiated 10 years ago by the
InterRidge Program to promote and coordinate long-term multidisciplinary monitoring of
hydrothermal vents in the Azores region of the Mid-Atlantic Ridge This coordinated plan aims at
determining the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to
understand how hydrothermal ecosystems couple with these sub-surface processes, and how this
affects exchanges with the ocean.
Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK (geodesy),
and BBMoMAR (sismology and MT) experiments and will be further implemented in 2008 with the
deployment of autonomous temperature probes at selected vents.
The MoMAR-D project was selected by ESONET as a demonstration mission to deploy and manage a
multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large
hydrothermal field located in the center of one of the most volcanically active segment of the MAR.
Monitoring this field offers a high probability of capturing evidence for volcanic events, observing
interactions between faulting, magmatism and hydrothermal circulations and, evaluating their links
with the dynamics of hydrothermal fauna.
We will use the SEAMON technology developed during the ASSEM EC project, with two nodes
acoustically linked to a surface buoy that will ensure satellite communication to a land base station.
The system will comprise 2 scientific nodes: a geophysical node moored in the Lucky Strike lava lake,
and a geochemical/ecological node at the Eiffel Tower vent site. This observatory infrastructure will
acquire a synchronized multidisciplinary data set, and allow us to develop solutions for sensor
interoperability, shore-sensor interactive communication, data management and dissemination, and
public outreach.
The project comprises two multidisciplinary ROV cruises (MoMARSAT), the first one in 2010 to
deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike vent field and
the second one in 2010 to recover it. The study area belongs to the Portuguese ZEE and is part of a
planned OSPAR “Marine Protected Area”.
In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet Committee.
After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, the
preliminary schedule was withdrawn and the cruise proposal had to be submitted once again to the
French Fleet Committee. We are waiting for the results of this evaluation and the new 2010-2011
schedule.
Nevertheless, the first MoMAR-D plenary meeting took place in March (17-18) 2009 in Ifremer centre
de Brest and gathered around 20 scientists and engineers from France, Germany and Portugal. The
objectives of this meeting were:
1- The scientific and technological presentation of the different planned experiments by each
partner, chair M. Cannat,
2- A description of the operational system by J. Blandin
3- The preparation of interfacing and shore trial step by J. Blandin (see Deliverable 2)
4- The preparation of the data management policy chaired by T. Carval and P.M. Sarradin,
deliverable 3.
5- The preparation of the communication plan (regional, national and EU initiatives) by J.
Sarrazin (deliverable 4).
This meeting allowed proposing a new planning for the interfacing and shore trial step:
• Development, adaptations and testing of sensors should be finalized by the end of December
2009.
• Integration to SEAMON is planned in January 2010.
• A test of the whole system should be carried out by the end of February 2010.
• Shipping is planned for May 2010.
A first draft of the data management policy (deliverable 3) is circulating among the partners. A final
version agreed by everybody is awaited in September 2009.

Work Performed :
WP1 and 2: We have participated in the March 09 kick-off meeting in Brest. We have done significant
work toward integration of the SEAMON-connected sensors our institute has taken responsibility for
(pressure probes and OBS). We have also made progress on processing of seismic monitoring of the
area in 2007-2008. These results are critical for the calibration of the seismic alert system for the
SEAMON-connected OBS.
WP3: we have contributed to the MoMAR-Demo Data management policy document which is now
nearly ready to be signed by all partners.
WP4: we have made progress in building the GIS database for the MoMar sites. We plan to release a
simplified version of this database on a web-based interface later this year.

Task 1-3.1: Manufacturing of two duplicate devices with enhanced electronics for autonomous
operation (data logging, self calibration)
New datalogger developed and tested in situ to 3600m for short term deployment (~15 hours repeated
5 times), need long term testing. The datalogger has up to 4Gb of data storage and can communicate
using RS232 in real time at 1Hz for the data rate. It is low power (24V < 10mA) and has smart
electronics to enable valve control and timed data acquisition.
Issues with fluidics handling slowdown the development of the sensors. Solution identified and under
development and test.
contractors involved : NOCS, main research engineer: Dr Cedric Floquet
Task 1-3.2: Reagent stability enhancement, improved in situ calibration and fouling reduction
techniques
PhD student working FT on characterizing the susceptibility to biofouling of the materials used to
manufacture the sensors.
Task 1-3.3: Integration to SEAMON
Not started. Likely to be RS232 com with 1Hz data rate. System will need power from DeepSea
Power and light type battery (24V 32Ah). Exact power requirements not known yet.

Contribution to WP1
- V. Chavagnac and C. Boulart participated to the kick-off meeting of the MoMAR-D program. The
two-days meeting took place at IFREMER in Brest in March 2009.
- The main scientific objective of the LMTG is to determine the chemical and gas composition of
hydrothermal fluids. This requires gas-tight Ti syringes which are not adapted at present for hightemperature fluid. We have therefore ordered Titanium tubing to make Ti canule onto the IFREMER
multi-sampler via the mechanical workshop at the LMTG.

Workpackage objectives and starting point
WP1. This workpackage concerns the scientific coordination of the multidisciplinary experiments
planned at Lucky Strike as part of the demo mission. All demo partners are involved in this WP.
Progress towards objectives –
The experiment is still in its preparation stage, because the cruise for the initial deployment
of the system has been scheduled provisionally in the summer of 2010 only. We have used
the additional year to progress on technological developments made in order to insure the
connection of sensor packages to the SEAMON system, but have officially launched the
demo at the kick-off meeting in Brest in march 2009.
Deviations from the project work programm, and corrective actions taken/suggested (identify the
nature and the reason for the problem, identify partners involved)
We will not be able to go ahead with the temperature array (partner NOC) we were hoping to
deploy to monitor changes in the temperature at diffuse venting areas.
Corrective actions:
We are looking at other means to get some of these diffuse venting temperature data,
including use of a sensor deployed previously in the Gulf of Cadiz.

Workpackage objectives and starting point (max 500 characters)
i) The objective of this WP is to establish and define a data management policy and procedure agreed
by all the partners. The principles to be specified are: i) the definition of the data to be acquired, ii) the
procedures of control for these data and the definition of metadata in accordance with the standards
recommendations on data documentation, and finally iii) the dissemination level.
ii) An important task will be to develop links between the MoMAR-D and the data management
systems currently used for volcanic and seismic monitoring, and for ecosystem inventory and
surveillance, at and near the Azores Islands. To this aim, we have secured the participation of
colleagues from the Centro de Vulcanologia e Avaliação de Riscos Geológicos, and from the
Department of Oceanography and Fisheries of the University of the Azores.
i) Data management principles were discussed during the first meeting in Brest (March 209). A draft
document, based on documents issued from Neptune Canada, ESONET and Eurosites, has been
written by T. Carval and P.M. Sarradin and is circulating amongst the partners for modifications. A
final document (Deliverable 3) agreed by all the partners should be available in autumn 2009.
ii) The Centro de Vulcanologia e Avaliação de Riscos Geológicos was present in Brest for the first
meeting and presented us their work.
Deviations from the project work programme,
D3 was planned in March 2009. Data management was discussed during the first MoMAR D meeting
in Brest in March 2009. We have delayed the delivery of D3 in autumn 2009.

The MoMAR-D demonstration will undertake to comply with the MPA rules and develop a coherent
experimental site management plan. This plan will include a set of rules for PI’s, based on the MPA
code of conduct and on the InterRidge code of conduct. These rules will aim at minimizing the impact
of research on the environment, and at ensuring the compatibility of all the experiments planned.
To enforce these regulations, we will make provision in the MoMAR-D demonstration project for a
coordinating MoMAR office, probably at Horta (but a centralized ESONET site management office
may also be envisioned) and develop formal links with the Portuguese maritime authorities (the
Hydrographic Institute), with the MPA managing authorities, and with the Azores Regional
Government. Partners from the Centro de Vulcanologia e Avaliação de Riscos Geológicos, and from
the Department of Oceanography and Fisheries of the University of the Azores will play a leading role
in this task.

Near real time transmission of data (and video images) from the vents will open new opportunities for
public outreach. The public outreach strategy will include press conferences before the cruises,
maintenance of a cruise web site, and organization of a live event from the vessel, with video
conferences and transmission of live images from the seafloor, participation of journalists interested in
making a movie out of this seafloor observatory adventure. Our plan is to have a permanent exhibit,
with access to the most recent data and images from the seafloor, at the Oceanopolis aquarium in
Brest. Mirror sites and exhibit material could also be set in other large aquariums in Europe.
The strategy will cover international to regional initiatives such as the production of a didactic kit, in
Portuguese, on hydrothermal vents and seafloor observatories for the different school levels, in
connection with in the Azores University.
The public outreach strategy was discussed during the first meeting in Brest in March 2009. The
communication plan will be available in July 2009 (Deliverable 4).

The objective of this WP is to submit a cruise proposal to the French Fleet Committee (D1). This
proposal gathers 2 20 days cruises using the French ROV Victor 6000. The first cruise will be
dedicated to the implementation of the observatory infrastructure in the Lucky Strike vent field, the
second one to its recovery 12 month later. Site studies will be performed during both cruises.
After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, this
preliminary schedule was withdrawn and the cruise proposal had to be submitted once again in
January 2009. We are waiting for the results of this evaluation and the new 2010-2011 schedule.
Deviations from the project work programme
The MoMARSAT cruise proposal was submitted 3 times to the French Fleet committee. In June 2009,
we have not got any certainty on the scheduling of the cruise in 2010 and 2011. This uncertainty led us
to delay the starting date of the MoMAR-D DM (September 2008), and to slow down the shore work.
With the new agenda, only the first cruise in would 2010 fit in the ESONET calendar. If the cruise is
delayed once again to 2011-2012, the project will be shifted out of the ESONET time schedule setting
the question of the future of the project and of the ESONET grant. In such a case, the objectives within
ESONET could be reduced to a shore trial of the complete observatory infrastructure.

The objective of MoMAR-D proposal is the deployment of an acoustically-linked multidisciplinary
observing system at the Lucky Strike vent field, with satellite connection to shore, and its management
during 1 year.
The first MoMAR-D plenary meeting took place in March (17-18) 2009 in Ifremer centre de Brest and
gathered around 20 scientists and engineers from France, Germany and Portugal. The objectives of
this meeting were:
The scientific and technological presentation of the different planned experiments by each partner,

• The preparation of the communication plan (regional, national and EU initiatives) by J.
Sarrazin (deliverable 4).
This meeting allowed proposing a new planning for the interfacing and shore trial step:
• Development, adaptations and testing of sensors should be finalized by the end of December
2009.
• Integration to SEAMON is planned in January 2010.
• A test of the whole system should be carried out by the end of February 2010.
• Shipping is planned for May 2010.
Deviations from the project work programme
This project is directly linked to the realization of 2 cruises to deploy and recover the observatory
infrastructure. In January 2008, the MoMARSAT cruise proposal was submitted to the French Fleet
Committee and prescheduled for the summer 2010. Unfortunately, this preliminary schedule was
withdrawn and the cruise proposal had to be submitted once again in January 2009. We are waiting for
the results of this evaluation and the new 2010-2011 schedule. In June 2009, we have not got any
certainty on the scheduling of the cruise in 2010 and 2011. This uncertainty led us to delay the starting
date of the MoMAR-D DM (September 2008), and to slow down the shore work. With the new
agenda, only the first cruise in would 2010 fit in the ESONET calendar. If the cruise is delayed once
again to 2011-2012, the project will be shifted out of the ESONET time schedule setting the question

Executive summary
The MoMAR (Monitoring the Mid-Atlantic Ridge) project was initiated 10 years ago by the
InterRidge Program to promote and coordinate long-term multidisciplinary monitoring of
hydrothermal vents in the Azores region of the Mid-Atlantic Ridge This coordinated plan aims at
determining the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to
understand how hydrothermal ecosystems couple with these sub-surface processes, and how this
affects exchanges with the ocean.
Monitoring at Lucky Strike has started with the MoMARETO (ecology), GRAVILUCK (geodesy),
and BBMoMAR (sismology and MT) experiments and will be further implemented in 2008 with the
deployment of autonomous temperature probes at selected vents.
multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large
hydrothermal field located in the center of one of the most volcanically active segment of the MAR.
Monitoring this field offers a high probability of capturing evidence for volcanic events, observing
interactions between faulting, magmatism and hydrothermal circulations and, evaluating their links
with the dynamics of hydrothermal fauna.
We will use the SEAMON technology developed during the ASSEM EC project, with two nodes
acoustically linked to a surface buoy that will ensure satellite communication to a land base station.
The system will comprise 2 scientific nodes: a geophysical node moored in the Lucky Strike lava lake,
and a geochemical/ecological node at the Eiffel Tower vent site. This observatory infrastructure will
acquire a synchronized multidisciplinary data set, and allow us to develop solutions for sensor
interoperability, shore-sensor interactive communication, data management and dissemination, and
public outreach.
The project comprises two multidisciplinary ROV cruises (MoMARSAT), the first one in 2010 to
deploy the acoustically-linked multidisciplinary observing system at the Lucky Strike vent field and
the second one in 2010 to recover it. The study area belongs to the Portuguese ZEE and is part of a
planned OSPAR “Marine Protected Area”.
After evaluation, the cruise has been prescheduled for the summer 2010. Unfortunately, the
preliminary schedule was withdrawn and the cruise proposal had to be submitted once again to the
French Fleet Committee.
The cruise is now scheduled in September 2010, on the Pourquoi pas ? with the ROV Victor 6000.
Due to logistic constraints of the fleet, the duration of the first cruise was reduced from 19 to 13 days
to implement the observatory infrastructure on Lucky Strike.
After the meeting in Brest in March 2009 and the final definition of the observatory, this period was
used to start the technological work. The design and building of the sensors and nodes is in progress as
well as the software adaptation of the sensors to the SEAMON technology. The objective is to start the
trial step in Brest in Spring 2010. Shipping is planned during Summer 2010.
In parallel, a draft of the data management policy is circulating among the partners (see draft of D3).
The MoMAR-D project was presented during the 4th International symposium on Chemosynthetic
Based Ecosystems in Okinawa (Jpn), the ESONET All region workshop in Paris, the ESONET
Best practices workshop in Brest and the Ocean Biology Observatory Workshop in Mestre
(It).
The next 6 month period will be devoted to the on shore integration and trial of the system in Ifremer
in Spring 2010.
D3 and D4 will be finalized before the cruise.
The cruise preparation reports (Agreement to work in the Portuguese waters and Technological
description of the cruise) will be delivered to the French Fleet in March 2010.

Cedric Boulart participated to the ESONET meeting in Paris the 5 – 7 October 2009.
We have bought the electronic/optical- material from Nomadics to build the main structure of the
dissolved methane in-situ sensor. We have also received from the ENS Chimie de Lyon (J.-P. Dutasta)
a large quantity of the supra-molecule “Cryptophane-A” which is specially adapted to methane and
which is the base of the sensor. We have build, in parallel, a bench-top set-up necessary to calibrate
the methane sensor at atmospheric pressure. We are now in the phase of integrating the different
component of the methane sensor using the infrastructure of the LAAS (Toulouse) before starting the
first tests of methane detection in water at atmospheric pressure.

A draft of the Data management policy is circulating among the partners and will be finalized before
the cruise.
The MoMAR-D project was presented during the 4th International symposium on Chemosynthetic
Based Ecosystems in Okinawa (Jpn), the ESONET All region workshop in Paris, the ESONET
Best practices workshop in Brest and the Ocean Biology Observatory Workshop in Mestre
(It).
A post doctoral grant was submitted and accepted by Ifremer and the European project Hermione. The
PI are Pierre-Marie Sarradin (Ifremer), Jozée Sarrazin (Ifremer) and Grégoire Mercier (Télécom
Bretagne).
Elaboration of a video processing platform to analyze the temporal dynamics of hydrothermal
ecosystems.
Located on oceanic ridges, hydrothermal ecosystems are characterized by strong physico-chemical
gradients and the presence of a unique fauna, sustained by microbial chemosynthesis. Several studies
have shown that the spatial distribution and composition of vent faunal assemblages were strongly
correlated to geological, physical and chemical processes at different spatial and temporal scales, but
almost no data are available on the temporal dynamics of these ecosystems. The major objective of
this post-doctoral research position is to develop a video processing platform to analyze the temporal
dynamics of hydrothermal ecosystems. This data along with the abiotic data measured within the vent
environment will be analyzed and compared using multivariate statistics. Finally, all the data will be
further processed through a GIS that will allow for a graphical representation of all of the observed
temporal variations. More specifically, we are looking to answer the following questions : (i) What
biological and geological data can be automatically extracted from video imagery to feed the temporal
database and (ii) what are the different scales of variations linking environmental changes and the
ESONET MoMAR-D
46
dynamics of the fauna in hydrothermal ecosystems ?
The acquired data will be used to better understand the influence of abiotic variations on deep-sea
animal communities. This post-doc will be one of the first using the new “deep-sea observatory”
approach. Expected results may then provide fundamental knowledge on the functioning of deep-sea
ecosystems. This project is part of the European programmes ESONET (2008-2011) and HERMIONE
(2009-2012) of the 6th and 7th PCRD respectively.

Cette demande de campagne se situe dans le cadre du projet MoMAR-Demo soumis à l’appel d’offre
« demonstration missions » du NoE ESONET (A. Colaço et P.M. Sarradin). La plupart des équipes participantes
sont membres d’instituts partenaires de ce NoE. La décision de financement nous attribue 500 K€. Cette somme
permettra de couvrir la plus grande partie du développement technique nécessaire, ainsi que les coûts de
fonctionnement des différents instruments et une partie des frais d’analyse des données.
Les laboratoires et instituts des équipes participantes (appartenant à 4 pays européens) assureront les salaires
des personnels, le transport des équipes et du matériel, ainsi que les complément des frais de développement
technique et d’analyse des données.
L’étude de la dynamique temporelle de Tour Eiffel pourra être financée pour partie par l’ANR DEEP OASES. Les

RESUME - ABSTRACT
MoMARSAT
Abstract
The MoMAR (Monitoring the Mid Atlantic Ridge) initiative aims at providing multidisciplinary time-series data sets
for hydrothermal systems in the Azores region of the Mid-Atlantic Ridge.
MoMAR is a component of the ESONET project (European Seafloor Observatory Network). The ESONET Network
of Excellence (NoE, coordinated by R. Person, Ifremer) was launched by the EC in March 2007. The MoMARDemo project is partly funded by ESONET and concerns the 1 year deployment of an acoustically-linked
multidisciplinary observing system at the Lucky Strike hydrothermal vent field, with satellite connection to shore.
MoMARSAT 1 and 2 are the cruises planned to implement this MoMAR-Demo project. These ROV cruises, one in
2010 and one in 2011, will deploy, then recover, the acoustically-linked multidisciplinary observing system.
Lucky Strike is a large hydrothermal field in the center of one of the most volcanically active segments of the MidAtlantic Ridge. Monitoring therefore offers the best chance of capturing evidence for volcanic events, and for
interactions between faulting, magmatism, hydrothermal circulations and their impact on the ecosystem at a slowspreading mid-ocean ridge. Our project addresses five main themes and their links : seismicity and hydrothermal
activity, vertical deformation of the seafloor, chemical fluxes at Lucky Strike vents, ecology at Lucky Strike vents,
and physical oceanography.
We plan to use the SEAMON technology, with two nodes acoustically linked to a surface buoy that will ensure
satellite communication to a land base station. This system has been developed during the ASSEM-EC project and
successfully tested since. Specific solutions will be developped with our ESONET partners for sensor
interoperability, shore-sensor interactive communication, and data management and dissemination.
This observatory infrastructure will acquire a synchronized multidisciplinary data set, a subset of which will be
transmitted to shore in near real time (images of the seafloor, pressure and tilt at seafloor, a subset of fluid
chemistry and seismicity data). The rest of the data (fluid chemistry, temperature, oceanographic data, OBS data,
microbiological experiments) will be stored locally over the one year duration of the experiment. We will also
acquire punctual measurements, and fluid and biological samples, during the 2010 and 2011 cruises.
The near real time data will allow us to detect seismic, volcanic or hydrothermal events. We will have the capability
to respond to these events by changing sampling rates on some of our sensors, and, if needed, by mobilizing a
ship of opportunity.
The study area belongs to the portuguese ZEE and is part of a planned OSPAR “Marine Protected Area”.

Modifications du dossier par rapport à la version soumise en 2008.
La structure du projet reste la même. Il y a peu de changements dans les participants. La stratégie
d’instrumentation est inchangée. La stratégie de la première campagne (MoMARSAT 2010) est
cependant modifiée puisque nous ne sommes plus dans la position de devoir coordonner cette
campagne avec Bathyluck. Toutes les composantes du projet se retrouvent donc dans la même
campagne ce qui simplifie le plan de campagne et devrait répondre à la remarque #3 du rapport
d’évaluation (reproduit en page suivante). Il en résulte un allongement de quelques jours de la durée sur
zone demandée.
Remarquons à ce sujet que cette complexité dans notre dossier de 2008 résultait directement du retard
d’un an du programme de Bathyluck du fait de l’annulation des campagnes de ROV-Nautile sur Lucky
Strike en 2007. Cette annulation (due à divers problèmes techniques de Genavir) a également décalé
d’un an la récupération des données des premiers capteurs installés sur Lucky Strike en 2006 pendant
les campagnes MoMARETO et GRAVILUCK. Ceci explique, les données n’ayant été récupérées qu’en
été 2008, que la valorisation de ces campagnes puisse être vue comme insuffisante (remarque #5)….
Encore que le nombre d’articles publiés récemment pour ces deux projets soit de notre point de vue loin
d’être négligeable (cf Fiches de Valorisation en fin de dossier).
Il peut être utile de préciser ici que le suivi long terme de la sismicité mené par le projet BBMoMAR a
débuté en 2007 et que les données ont également été récupérée en 2008 (cf Fiche de Valorisation
BBMoMAR en fin de dossier). De ce fait aucun résultat n’est encore publiable.
Les modifications du dossier concernent donc essentiellement sa forme. Nous avons révisée le
Document 1 pour mieux faire apparaître les hypothèses à tester et les paramètres à mesurer (remarque
#1). Nous avons rajouté une figure et des explications illustrant l’importance de la contribution des
données de sismique de SISMOMAR pour la relocalisation prévue de la sismicité et pour la
compréhension générale du contexte des circulations hydrothermales de Lucky Strike (remarque #4).
Remarquons que les 3 thèses soutenues dans les derniers 6 mois sur ces données sont actuellement en
cours de publication (cf Fiche de Valorisation SISMOMAR en fin de dossier).
Nous avons également expliqué pourquoi l’activité magmatique actuelle de Lucky Strike, avérée par la
découverte pendant SISMOMAR d’une probable lentille magmatique, en fait un site exceptionnel pour
l’installation d’un observatoire, et clarifié la stratégie du projet MoMAR qui prévoit également
l’instrumentation du site à substratum ultrabasique Rainbow (ceci pour répondre à une remarque d’un
des reviewers).
Toujours dans le document 1, nous avons clarifié et étoffé la présentation du système SEAMON, des
capteurs à connecter, et de l’état de préparation technique du projet (remarque #2). Nous avons rajouté
deux tableaux des capteurs. L’un dans le Document 1 (§4) concerne tous les capteurs et permet
d’apprécier les développements prévus, l’autre, dans le Document 2 (§5), donne les flux de données
transmises et l’énergie requise pour cette transmission pour chacun des capteurs à connecter.
Enfin, dans le § 3-3 du Document 1, nous clarifions notre stratégie pour ce qui est des capteurs
chimiques (remarque #2). Nous ne dissimulons pas le fait, reconnu dans tous les colloques de
prospective sur les observatoires fond de mer, que peu de capteurs adaptés sont opérationnels pour le
suivi long terme des fluides hydrothermaux profonds. Notre projet vise donc à combiner suivi long terme
avec quelques instruments disponibles, mesures ponctuelles répétées, et développement de quelques
prototypes
prometteurs.

Avis de la commission:
Le projet MOMARSAT-D entend déployer un observatoire fond de mer pluridisciplinaire,
non câblé (transmission acoustique puis par satellite) et interactif pour étudier pendant une durée
minimum d’un an, un système volcanique actif à l’axe de la dorsale atlantique et son interaction avec
l’environnement (zone Momar-Lucky strike). Ce projet, soutenu par ESONET (European
Observatory Network), est ambitieux, pluridisciplinaire, et présente une forte composante
technologique. Il a valeur de test pour des observatoires fond de mer, non-câblés.

Comme indiqué par la précédente commission, la problématique scientifique est abordée
en termes très généraux. Le dossier ne contient pas d’hypothèses précises à tester et les différents
prélèvements à effectuer ne sont pas toujours clairement justifiés. La commission considère
néanmoins que l’analyse croisée de séries spatio-temporelles longues de nombreux paramètres
(sismicité, déformation, température et composition chimique des fluides et la dynamique des
écosystèmes hydrothermaux) est porteuse de découvertes qui devraient permettre de mieux
comprendre le couplage entre la dynamique des écosystèmes, les processus tectoniques et
volcaniques, les processus hydrothermaux et les flux thermiques.
La commission s’inquiète cependant des nombreux développements, tests et validations
d’instruments et de connexions restant à effectuer avant la programmation éventuelle de cette
campagne en 2009. En particulier, la commission devra s’assurer que les capteurs géochimiques
seront opérationnels à la date de la campagne . La commission souhaiterait d’autre part, être mieux
informée sur le type et les flux de données à transmettre en temps réel. Pour cela, un tableau
récapitulatif de tous les paramètres à acquérir indiquant leur fréquence d’acquisition, et le volume de
données transmises en temps réel par mode acoustique permettrait de se faire une meilleure idée
de l’ambition et des garanties qu’offre ce projet. La campagne 2009 présente un calendrier
prévisionnel bien ajusté (14 plongées en 19j) pour mener à bien l’installation du dispositif et collecter
les données nécessaires sur chaque site. A ce jour, aucun calendrier précis n’est prévu pour la
campagne 2010 dont l’objet sera essentiellement de récupérer les instruments et d’acquérir des
données complémentaires. Le lien avec la campagne Bathyluck09 n’apparaît pas clairement dans le
dossier. Il est parfois difficile de savoir qui fait quoi et où? Des reconnaissances de sites à
instrumenter ainsi que l’échantillonnage de fluides sur ces sites apparaissent dans les deux
dossiers. Le courrier adressé à la commission par le comité de pilotage ne vient que partiellement
lever certaines ambiguïtés. Il est aussi regrettable que les données OBS de la campagne
SISMOMAR ne soient pas utilisées pour caractériser la structure de la zone d ‘étude.
La valorisation des campagnes précédentes sur le site MOMAR est considérée comme
très inégale, particulièrement en sciences de la terre et doit être une priorité du groupe MOMAR.
Malgré les réserves mentionnées ci-dessus la commission, consciente des enjeux et du
calendrier liés à ESONET, a classé MOMARSAT09 en priorité 2a.

DOCUMENT N° 1
MoMARSAT
PROJET SCIENTIFIQUE ET TECHNOLOGIQUE
Section 1 .Context of the proposal
ESONET is an EC Network of Excellence coordinated by R. Person (Ifremer), for the construction of a network
of deep seafloor and water column observatories around Europe. The Azores node of ESONET is dedicated to
the long-term observation of deep sea ecosystems and of active processes related to seismicity, volcanism,
and hydrothermal circulations in the Azores region. It is planned to extend the islands seismic and volcanic
monitoring system offshore, and to provide holistic information concerning hydrothermal and seamount
habitats, essential for the ecosystem-based management of the region. It will also monitor the movements of
deep water masses and the consequences of thermohaline circulation changes in the North Atlantic on climate
and on biodiversity.
MoMAR (“Monitoring the Mid-Atlantic Ridge”) is a
component of the work planned at the Azores node
of ESONET, which focuses on active processes at
ridge hydrothermal systems. Seawater circulates
through the permeable oceanic crust, exchanges
chemicals with the surrounding rocks, and is heated
to temperatures reaching 400°C. This hot fluid flows
up and is expelled at hydrothermal vents, forming
black smokers and diffuse vents. Hydrothermal
circulation at mid-ocean ridges therefore impacts the
transfer of energy and matter from the interior of the
Earth to the crust, hydrosphere and biosphere. The
unique faunal communities that develop near the
vents are sustained by chemosynthetic micro
organisms that use reduced chemicals presents in
the hot fluids as energy sources.
Small active chimney, Lucky Strike (MoMARETO 2006)
Environmental instability resulting from active mid-ocean ridge processes (e.g. seismicity) can create changes
in the flux, composition and temperature of emitted hydrothermal fluids and consequently can affect the
associated faunal communities. Existing data lack of the temporal resolution necessary to understand the
natural dynamics of this environment, and, therefore of the global consequences of these processes on the
ecosystems and on the transfer of energy and mass from the Solid Earth to the Ocean.
MoMAR develops a multiscale and multidisciplinary approach whereby small-scale monitoring
experiments, such as chemical and biological recording at individual vents, are nested into larger scale
experiments (such as seismic and geodetic networks). Pilot experiments have been conducted over the
past few years at the MoMAR vent sites, using autonomous instruments. Two large vent fields are of
particular interest, Lucky Strike and Rainbow. The MoMAR-D demonstration mission (led by A. Colaço,
University of the Azores, and P.M. Sarradin, Ifremer) is supported by the ESONET NoE and focuses on
the Lucky Strike field. MoMARSAT 1 and 2 are the cruises planned to implement the MoMAR-D project.
Section 2: The MoMAR study area: setting and summary of previous work
The Mid Atlantic Ridge (MAR) near the Azores comprises 4 known hydrothermal vent fields, each with its own
specific geological, chemical, hydrothermal, volcanic and biological characteristics (Lucky Strike, Rainbow,
Menez Gwen, and Saldanha; Figure 1). It has been the focus of a great number of cruises in the past few
years, as part, successively, of the FARA program (French-American Ridge Atlantic), the MARFLUX (MAST II
EC program), AMORES and ASIMOV (MAST III EC program) and VENTOX (Framework V), EXOCET/D
(Sarradin et al, 2007) and MoMARNET (Framework VI; Cannat et al.) European projects. Most of these cruises
have been primarily funded through the French system. The geological-geophysical background of the region is
well constrained, as are the general characteristics of the known hydrothermal vents, and the broad diversity of
the associated fauna (in terms of megafauna but not for microbial or meiofauna).

Lucky Strike is located at the summit of an axial volcano at 1700m depth. It is underlain by a recentlydiscovered mid-crustal magma chamber (Singh et al., 2006). The site shows sustained levels of microseismicity (Dusunur et al., 2008), and a possible magmatic diking event occurred in 2001 (Dziak et al., 2004).
Recent vent fluid chemistry data (Pester et al., 2008) indicate high CO2 concentrations which could suggest
degassing of a recently emplaced new batch of magma in the melt lens. Lucky Strike is one of the largest
hydrothermal field found along the Mid-Atlantic Ridge. Over 100 hydrothermal vents surround a relatively flat
lava lake formation (Fouquet et al., 1995; Ondréas et al., in press). Vent fluid temperatures range from 330ºC in
black smokers, to 200-212ºC and even <20ºC in very diffuse emissions (Cooper et al., 2000; Von Damm et al.,
1998). Fluid chemistry indicates two distinct sources for the vents in the area (Charlou et al., 2000), suggesting
complex hydrothermal cell dynamics. While temperatures appear to be very stable over a time scale of a few
years at some vents (i.e., Tour Eiffel, 324±1°C), others show variability of up to 40°C [Statue of Liberty, 202185°C; Sintra, 176-215°C; (Charlou et al., 2000) and personal communication].
Discovered in the nineties (Langmuir et al., 1997), the Lucky Strike vent field has since been the object of many
cruises, addressing its geological and geophysical characteristics (Humphris et al., 2002 ; Miranda et al.,
2005 ; Ondréas et al., 1997, in press; Escartin et al., 2008). The dynamics of water masses in the area has
been extensively surveyed in the summer of 2006 (Graviluck cruise; Thurnherr et al., 2008), showing strong
bottom currents and a clear link between high levels of diapycnal mixing in the abyss and the rough topography
of the axial valley walls.
On most vents, faunal communities are visually dominated
by mussel beds of Bathymodiolus azoricus partially
covered by microbial mats. The vicinity of active hightemperature chimneys, flanges and cracks are colonized
by Chorocaris chacei / M. fortunata shrimp assemblages
(Desbruyères et al. 2001). B. azoricus live in symbiosis
with microbial endosymbionts (sulphide oxidizing- and
methanotrophic bacteria (Fiala Medioni et al., 2002) and
are capable of migrating along sulphide gradients. B.
azoricus seems to be able to use two of the energy
sources present in the hydrothermal fluids (CH4 and H2S)
as well as particulate organic matter through filter feeding.
The faunal assemblages dominated by Bathymodiolus are
present in the cold part of the mixing zone sustained by

probes after 12 month, MoMARETO 2006
The first two cruises officially sponsored by MoMAR carried out site survey work, acquiring heat flux
measurements (Luckyflux 2003; Lucazeau et al., 2006), and seismic data (SisMoMAR 2005; Singh et al., 2006;
Crawford et al., in press). Monitoring was initiated in 2005 with the deployment of an Array of Autonomous
Hydrophones (AAH) for regional seismic monitoring (first MARCHE cruise). In 2006, this network was
redesigned for a better coverage of the MoMAR area. It has been maintained twice now (2007, 2008), and 3
years of data have been collected. A thesis and 2 papers are in preparation on the first 2 years of data (Simao,
Goslin et al.). The 3rd year is being processed now, jointly with the first year of recording of the Lucky Strike
OBS network, which is currently operational (check location map in Document 2), and has been operated since
2007 (BBMoMAR).

In 2006, the GRAVILUCK (Ballu et al.) and MoMARETO (Sarrazin et al. 2006) cruises deployed two pressure
gauges, an oceanographic mooring, and the TEMPO module (video camera, chemical analyzer, temperature
probes connected to a SEAMON node) on Lucky Strike. These autonomous instruments could unfortunately
not be serviced in 2007, due to the cancellation of the MoMAR ROV cruises to Lucky Strike. The instruments
were finally recovered last summer (MoMAR2008-Leg1 cruise) in variable states of corrosion (new pressure
probes were then deployed for one more year of recording). Recovered data include one year of oceanographic
data and of pressure probe recording, 45 days of video sequences, 18 months of fluid temperature, and 6
months of fluid chemistry (TdFe). We are now processing these data, and assessing the state of each
instrument in view of their redeployment during MoMARSAT. Details on this may be found in Section 4.
As we write these lines, long (> 1 month) time-series data collected at the MoMAR sites therefore include : the
regional seismicity record (AHA array): 2005-2008, the OBS record at Lucky Strike: 2007-2008, and the
pressure probe, oceanographic and ecology data listed above (recovered in 2008). All of these data, except the
first 2 years of AHA recording, were collected less than 5 months ago and are being processed now.
The Bathyluck09 cruise (PIs J. Escartin-A. Deschamp) scheduled in the summer of 2009 will carry out
additional site survey, service the OBS array and the pressure probes, deploy temperature probes and perform
fluid sampling in venting areas.
Further information on the MoMAR cruises may be found on http://www.momarfr.org.
Section 3: Scientific objectives and experimental design of the
MoMARSAT / MoMAR-D project
Lucky Strike is at present one of the most magmatically active segments of the Mid-Atlantic Ridge (MAR). This
is important because magmatic activity at slow-spreading ridges is known to be episodic, with short periods of
eruptions, and longer periods of faulting of the newly emplaced lava. The duration of these periods is not well
constrained, but crustal melt bodies which can produce eruptions have so far only been detected
unambiguously in two segments of the MAR: Lucky Strike, and one segment South of Iceland (Sinha et al.,
1997). This suggests that volcanic activity may last only a small fraction of the time (a few hundred thousand
years) it takes to build the crust at the MAR axial valley. Capturing this short, but critical period is the principal
asset of Lucky Strike as a monitoring site. The presence of magma in the crust, near seismically imaged normal
faults (Figure below), and in association with high temperature hydrothermal discharge, offers a unique
opportunity to study the feed-backs between volcanism, deformation, seismicity, and hydrothermalism, and to
understand how the hydrothermal fauna (including microbes) couples dynamically with these sub-surface
processes.
Basalt-hosted hydrothermal systems such as Lucky Strike are powerful component of the heat exchange
machine at slow-spreading ridges. The other component is ultramafic-hosted systems such as Rainbow, where
detachment faults leading to mantle exhumation probably control hydrothermal circulation. The present
proposal focuses on Lucky Strike as one element of this complex slow-spreading ridge system. The
technological achievements of the MoMARsat experiment will be directly transferable to future monitoring of
Rainbow-type vents, which is an integral part of the MoMAR plan.
Experiments planned at Lucky Strike belong to 5 thematic packages exploring the dynamics of the geosphere,
its impact on the characteristics of the hydrothermal fluid (temperature and composition), and on the associated
fauna and finally the exchange with the ocean. Each of these have been addressed to some extent in previous
cruises and funded projects of the MoMAR “chantier”, through the deployment of autonomous sensors or
temporally limited site studies. The MoMARSAT-MoMAR-Demo pilot experiment will represent a significant
step towards effective integration of these multidisciplinary experiments in a coordinated seafloor observatory
design. The Hydro-MoMAR or MARCHE 3 cruise proposal submitted by J. Perrot and J. Goslin for
maintenance of the regional hydrophone array in 2010-2011 has strong links with MoMAR-Demo because it
will, if funded, allow us to reinforce our interpretation of local seismicity at Lucky Strike (see § 3.1).
3.1 Thematic Package 1: Seismicity and hydrothermal activity
Hydrothermal circulations are primarily controlled by the permeability structure of the substratum, and by the
distribution of heat sources. Mid ocean ridges, and particularly slow-spreading ones, are active extensional
areas. A long-standing hypothesis (e.g. Wilcock and Delaney, 1996) is that cracks, fissures and faults play a
major role to control the spatial and temporal evolution of permeabilities, while magma emplacement within the
crust controls the distribution of heat sources. Based on seismic imaging (see Figure below with the eastern
axial valley bounding fault imaged at depth very near the axial melt lense), Lucky Strike appears as an
excellent place in which to test this hypothesis.
Cracking and displacements along faults are expressed by seismicity. Magmatic events such as dyking, and
other forms of magma displacement within the crust may also trigger seismicity. Tectonic and magmatic
seismic events have specific characteristics, particularly in terms of the stochastic distribution of magnitudes.

Seismic monitoring of hydrothermal fields and their surroundings is therefore an efficient method to monitor the
tectonic and magmatic events that likely control hydrothermal dynamics. Changes in the dynamics of
hydrothermal circulation, on the other hand, are expected to result in variations in the temperature and
chemistry of vent fluids. Statistical correlation between variations of the vent fluids, and seismic activity is
expected if seismicity does play a role to maintain high permeabilities, allowing for hydrothermal circulation at
and near the faults which connect to the crustal melt lens. Relocation of seismic events will also allow us to
refine our understanding of the links between specific seismic sources (e.g. the eastern boundary fault in the
figure below, or the inferred domain of high temperaure gradient surrounding the low velocity domain of Lucky
Strike volcanoe), and the hydrothermal convective system.
Evidently, we expect complexities in this signal, revealing the complexities of fluid upflow paths, and of
processes in the hydrothermal reaction zone. The link between seismicity and vent fluid temperatures has been
used before as a powerful constraint on numerical models of the permeability distribution at hydrothermal sites
in the Pacific (Sohn et al., 1998; Wilcock, 2004). We plan to adopt a similar monitoring and modelling approach
at Lucky Strike. A comparable combined temperature/seismicity experiment has been carried out over a one
year deployment at the TAG hydrothermal field, a Mid-Atlantic Ridge vent field located above a detachment
fault (Sohn, 2007a ; 2007b).
The experimental design for this thematic package consists in arrays of OBSs (Ocean Bottom Seismometers),
and of temperature (T) probes to monitor fluid temperature. Lucky Strike is a large vent field and it is important
to be able to check whether the variations detected affect fluids throughout the area, or just locally. Off the shelf
autonomous temperature probes are cheap and reliable. This, and the paucity of operational chemical sensors
(see §3.3), justifies our choice of temperature as the parameter to monitor at this wider scale. We plan to
examine the link between temperature time series and chemical signature of the fluids obtained locally using
chemical sensors (see §3.3) and discrete fluid sampling.
The local seismicity record will be processed to determine hypocenter locations and to model magnitude and
focal mechanisms. Excellent characterization of near site seismic velocity structure is available for this purpose
from the SisMOMAR cruise (Seher et al., in prep; Crawford et al., in press; Figure below). We have so far
processed only 6 days of passive seismic data (in between shooting times of the SISMOMAR cruise). It
suggests that strong temperature gradients, indicative of hydrothermal cooling, surround the axial melt body.
The full year of data collected this past summer (BBMoMAR2 cruise) will help to refine this preliminary picture.
Interpretation will be reinforced by integrating these local data with the regional hydrophone seismicity record
(Hydro-MoMAR or MARCHE 3 cruise proposal submitted by J. Perrot and J. Goslin). The Lucky Strike OBS
network does not have the coverage to locate events more than 10 km away from the volcano summit (see
location map in Document 2). Event relocation with the AHA array has a low resolution and no depth constrain,
but covers >300 km of ridge length north and south of Lucky Strike. It will therefore be used to understand the
regional distribution of seismicity, and to determine whether or not a seismic event recorded at the Lucky Strike
volcano belongs to a swarm of seismicity extending off the volcano, which typically would be the case for
seismicity linked to dike injection events. Tidal forcing on fluid temperatures will also be analyzed, and modeled
in terms of crustal permeability (Schultz and Elderfield, 1997).

are to the north or south). No vertical exaggeration. Red line

is inferred to contain a small fraction of melt (Seher et al., in
prep.). One deep earthquake occurred within one km of this
low velocity region indicating that lateral thermal gradients
are high. Dashed red line shows inferred melt solidus
(~1100°C isotherm). Blue arrows show inferred
hydrothermal flow paths (from Dusunur et al.,2008).
Work on this thematic package is ongoing with the Lucky Strike OBS network (BBMoMAR cruises; PI W.
Crawford; location in Document 2), and with the temperature sensors funded by the MoHTESIEM ANR (PI J.
Escartin) which will be deployed during the BATHYLUCK cruise this summer (2009). MoMARSAT will maintain
these networks of autonomous instruments for one more year (2010-2011).
For MoMARSAT, the experimental design will include ~25 autonomous low (<100°C) and high T sensors
(<400°C) deployed in vents throughout the study area. A small number of low T probes at diffuse venting areas
will be connected to the SEAMON system and data sent to shore on a near-real time basis. The MoMARSAT
experimental design also includes 4 autonomous short period OBSs from the University of Lisbon (with Guralp
sensors and SEND stations), and 4 short period OBSs from the Parc National INSU. These autonomous OBSs

will be deployed around the Lucky Strike volcano, complementing the autonomous Broad-band OBS station
operated since 2007 (NERIES program; Pis Crawford and Singh; see location figure in Document 2). In
addition, one modified OBS (IPGP) will be connected to the SEAMON system and will transmit a subset of the
seismic data via satellite. In the ongoing MoMAR-D preparation phase, solutions for data sampling adapted to
our event detection needs are investigated. These solutions involve counting events which have amplitudes
above a set of fixed thresholds, which will be chosen using the local seismicity record acquired in 2007-2008.
Our objective with this SEAMON-connected instrument is to obtain near-real time information on the level and
intensity of seismic activity to serve as a guide for our strategy of shore-sensors interactions (ex: increase
sampling rate of fluid chemical sensors or video camera in the event of a seismic crisis).
This experiment will use off the shelf technology but requires some work to adapt the modified OBS for
SEAMON connection and for deployment by ROV. We will use a standard 3-axis short period instrument, with
one processor for data acquisition and storage into the hard drive. A Persistor micro processor is added to
interface the SEAMON monitoring node. This interface has been used during the ASSEM EC experiment and is
currently being adapted to the OBS specifications.
3.2 Thematic Package 2: Deformation of the seafloor at the Lucky Strike volcano
Vertical deformation on active terrestrial volcanoes varies with the type of volcano and with its state in the
eruptive cycle. Surface deformation and mass movements are used at terrestrial volcanoes as powerful
constraints on models of magmatic and tectonic processes (e.g. Poland, 2006). In a seafloor spreading context,
strong extensional tectonics are superimposed on these volcanic cycles. The deformation of active volcanoes
in non-marine spreading rift contexts is often in the order of a few centimeters per year, as seen for instance in
Iceland (Jouanne et al., 2006; Sturkell et al., 2006). It can, however, also be of the order of 1 meter or more, in
dyke injection crisis such as the recent one in Ethiopia (Kendall et al., 2005), or the 1978 crisis in the Asal rift
(Ruegg et al., 1979). The tectonic setting at Lucky Strike presents many similarities with that of the EthiopianAfar rift system.
The primary hypothesis we wish to test is that vertical motions at a volcanically active mid-ocean ridge could
have the same order of magnitude. We also plan to investigate the links between these vertical motions and
tectonic and hydrothermal activity by integrating vertical ground motion information with seismic data, and with
fluid temperature and chemical data (Thematic Packages 1 and 3).
The MoMARSAT experimental design comprises 2 autonomous
pressure sensors, which have been deployed at Lucky Strike in 2006
(GRAVILUCK; PI V. Ballu), then recovered and replaced in 2008
(MoMAR2008-Leg 1). These instruments are set at the base and
summit of the Lucky Strike volcano (see location map in Document 2) to
monitor its deformation by a differential analysis. In addition, we plan to
perform a second measurement of the linear array of 10 geodetic
benchmarks (also on location map in Document 2), which has been
deployed and measured for the first time in 2006. Geodetic results on
terrestrial volcanoes indicate that ground deformation tends to be non
linear with time. Our permanent pressure gauges will allow us to assess
this variability at two locations, while the geodetic network links the two
pressure probes and should detect vertical displacements of the order of
1 cm (Ballu et al., 2008).
Pressure sensor deployed on the Lucky
Strike lava lake (Graviluck 2006)
The volcano summit pressure gauge will be connected to the SEAMON system for near real time data
transmission. This will require only minor work, because the gauge has been designed initially for connection to
this node during the ASSEM EC project. We will also collect data from an autonomous GPS station installed on
the BOREL buoy, in order to get the best continuous estimate of the sea surface height above the volcano. This
will be obtained after kinematic processing of the data, using a land based GPS station in the Azores. A series
of temperature sensors along the mooring line of the BOREL buoy (see § 3.5 Physical oceanography) will be
used to convert the sea level variations (buoy vertical movements) into pressure changes and to discriminate in
the pressure signal a vertical motion from a sea level change.
Finally, pressure data will be complemented by seafloor tilt and vertical acceleration data acquired with the
OBM (Ocean Bottom Motion meter) of the University of Bremen. This instrument is an integration of existing
parts of the Bremen Ocean Bottom Tiltmeter and the Bremen Ocean Bottom Accelerometer (OBA), which have
been deployed for a year at the Logatchev hydrothermal vent field on the Mid-Atlantic Ridge (Fabian and
Villinger, 2008). The OBM to be used in Lucky Strike also includes a high resolution absolute pressure-gauge
and a temperature data logger. It will monitor long-term sea floor deformations caused by quasi-static
processes like tectonics, magmatics, hydrothermal activity or slow mass movements nearby. The data will be

collected by a low-power high-resolution data logger. Data will be stored locally. We will also investigate
technical solutions to send a subset of these data through the SEAMON system.
3.3 Thematic Package 3: Chemical fluxes at Lucky Strike vents
The behavior of chemical species in hot hydrothermal fluid end-members provides critical information on the
conditions of fluid rock interactions in the hydrothermal cell (e.g. Charlou et al. 1991). These are susceptible to
change with time, due to geological processes (volcanism, tectonics, thematic package 1), or to instabilities
inherent to the hydrothermal convective system (Baker et al. 1995). Our planned experimental design aims at a
good integration between fluid characteristics and their evolution through time at the scale of the vent field (~1
km2) on the one hand, and the ecological approach developed at the scale of a few meters at the Tour Eiffel
vent site (in § 3.4) on the other hand.
The difficulty in this thematic package resides in the current lack of reliable sensors for long-term recording of
the most critical chemical parameters in deep sea hydrothermal fluids, such as chlorinity, H2S, silica, methane,
CO2 or hydrogen content. This limits the potential of chemical time series data for testing hypothesis pertaining
to both the small scale of vent habitats, and the larger scale dynamics of hydrothermal convection (e.g. is
phase separation (brine and vapor) an active mechanism? can we trace the nature of the reacted rocks and
how does it vary with time and from vent to vent?).
This difficulty is clearly expressed in the most recent documents generated by the seafloor observatory
research communities. It justifies the recent funding of the SENSEnet EC Marie Curie Network (PI D. Connelly)
which will promote development and testing of new chemical and biochemical sensors adapted to the
monitoring of fluid-controlled deep sea ecosystems. The experiment we plan will receive support from this
newly funded network, and be carried out through a collaboration of 3 active European teams. Despite its
limitations, this experiment should provide original documentation on the links which may exist between seismic
activity and fluid chemistry (§3.1), and between fluid chemistry and faunal distribution at Lucky Strike. Our
strategy will combine the use of the few available long term sensors, with fluid sampling and with discrete
chemical measurements during the two MoMARSAT cruises (2010 and 2011), enriched by the data obtained
during the Bathyluck-2009 cruise. We will also promote testing of new sensors.
For the future, we believe that having access to an operational multidisciplinary deep seafloor observatory
infrastructure such as the MoMARSAT SEAMON system will be a significant asset for developers of much
needed new long-term chemical sensors.
We will also deploy an in situ chemical analyser developed at NOC (Southampton) for the measurement of Fe
and Mn species. This continuous flow analyser will complement data from the CHEMINI Fe, T and O2 sensors.
CHEMINI is a component of the TEMPO module, which we plan to redeploy (it was deployed as an
autonomous sensor package during the MoMARETO cruise in 2006, and recovered in 2008), and connect to
the Tour Eifel SEAMON node.
The NOC Fe/Mn analyser has been deployed in Scottish sea lochs
(Statham et al. 2005) and in a hydrothermal setting aboard the
WHOI AUV “Abe” where it was successfully used in plume tracking
and vent location. Under the MoMAR-D project, two duplicate
devices will be manufactured. New electronics will provide
enhanced autonomous operation (e.g. data logging and self
calibration), and will be interfaced directly with the SEAMON node.
Methods for long term operation (e.g. reagent stability
enhancement, improved in situ calibration and fouling reduction
techniques) will be developed – previous deployments have all
been of short duration. The long term deployment of these sensors
is novel, and particularly so in a hydrothermal setting.
In situ measurements in Eiffel Tower vent, Lucky Strike
Other biogeochemical sensors are under development at NOC and, if they pass further trials, will be deployed
at Lucky Strike. Most promising is a dissolved Methane sensor (Boulart et al. 2008) developed as part of the
MoMARnet project. The detection method is based on refractive index modulation of a modified polymer
incorporating molecules of cryptophane-A, which have selective and reversible affinity for methane. The
refractive index is determined by surface Plasmon resonance with a limit of detection of 0.2 nM and a range of
1-300 nM. The MoMAR-D work plan for 2009 will focus on the optimization of this sensor (response time, noise,
and stability), the adaptation of the electronics, and the calibration under different ranges of pressure and
temperature. For the first MoMARSAT cruise, we expect to have a prototype which may be deployed for the
duration of the cruise, or used for mapping on the ROV.
We will also perform repeated sampling of the hot vent and diffuse fluids and analyze their composition (traces
and major elements, stable and radiogenic isotopic ratios, gases) on board the ship or back on shore

depending on the elements. We will focus on 5 vent sites of the Lucky Strike field (Tour Eiffel, Nuno, Y3, Statue
of Liberty and the vents near Pressure Gauge 1; see location map in Document 2) previously visited during the
Bathyluck cruise in 2009. These sites will also be equiped with autonomous temperature probes (thematic
package 1). Time-series data from the connected and autonomous sensors and geochemical data on discrete
fluid samples will be analyzed jointly in order to link the variability in hydrothermal fluid composition with other
parameters, and particularly fluid temperature, and seismicity .
To improve the link between the vent site-scale approach described above, and the meter-scale approach of
the ecology experiment (§3.4), we will deploy and test an innovative fibre optic temperature sensors array,
based on Fibre Bragg Grating (FBG) sensing technology. This temperature sensor system will allow us to
monitor fine scale variations in fluid temperatures, actual fluid chemistry being monitored at discrete locations
within the array. This will allow us to address the important question of whether (or at which scale) temperature
may be used as a proxy for fluid chemistry in fluid-controlled deep sea environments. Distributed
oceanographic temperature sensing using FBGs has precedent (Campbell et al., 2000; Mowlem M, 2002) but
use in hydrothermal applications is novel. For this pilot study, we will deploy a single, ~10 m-long, fiber optic
cable including the temperature sensors based on FBGs. We will purchase an “off the shelf” interrogation unit
from Smart Fibres Ltd. After laboratory based trials and calibration (including testing of sensors at pressure),
the interrogation unit will be housed in a suitable pressure vessel, with electronics, energy supply and data
logger.
3.4 Thematic Package 4: Ecology at Lucky Strike vents
Deep-sea hydrothermal ecosystems are extreme habitats, driven by microbial chemosynthesis and
characterized by strong endemism. They harbour faunal assemblages dominated by complex animal
communities associating microbial producers and secondary consumers that have co-evolved in a constraining
environment. Several studies have shown that hydrothermal communities are shaped by dynamic, small- and
large-scale geological processes which vary substantially in time and space. The spatial distribution of the
fauna can be linked to fluid characteristics including concentrations of chemicals (methane, sulphide, metals)
and fluid flow, to the type of substratum and also, to water depth (Sarradin et al. 1999; Sarrazin et al. 1999,
2002, Desbruyères et al. 2000, Le Bris et al. 2003, Sarradin et al. 2007, Cuvelier et al. submitted).
Hydrothermal faunal communities also exhibit significant temporal changes that are linked to the temporal
variability of their habitats and the ephemeral nature of energy sources (Sarrazin et al. 1997, Shank 1998).
Most questions related to the dynamics of these ecosystems and their couplings to geosphere-hydrosphere
processes remain unanswered due to the lack of long-term, simultaneous observations.
Edifice scale
Our recent studies on MAR faunal assemblages have been focussed on describing and characterizing the
structure, distribution and habitat of different species at the scale of the Tour Eiffel hydrothermal edifice. This
11m edifice is colonized by different faunal assemblages, visibly dominated by either Bathymodiolus mussels or
Mirocaris shrimps. Their spatial distribution appears to follow a systematic pattern on the entire sulphide
structure. We want to understand what controls this distribution: is it simply linked to environmental cues such
as distance from hydrothermal emissions, or is there a temporal succession pattern (Cuvelier et al. submitted)?
We are now looking at year-to-year variations to assess the dynamics of these faunal assemblages, using
video imagery acquired during several cruises (1994-2008, Cuvelier et al. in prep).
Small scale
The semi-quantitative study of 12 small sampling units located on the Tour Eiffel edifice (Sarrazin et al. in prep.;
Exomar and MoMARETO cruises 2005, 2006) has demonstrated significant differences of environmental
factors, and of the composition, diversity and biomass. Two distinct « assemblages » dominate our samples:
low-temperature (mean ∼4-7°C) Bathymodiolus/polychaete assemblages and medium temperature Mirocaris
fortunata assemblages (mean ∼ 7°-12°C, Sarrazin et al. in prep). A gradient of chemicals (CH4, total dissolved
Fe, pH, total dissolved H2S) is documented in each sampling unit, corresponding to the mixing of the hot fluids
with cold seawater. Dissolved copper follows a peculiar behaviour: a significant enrichment is observed in the
cold part of the mussel habitats, resulting from the oxidative dissolution of copper sulphide particles in the
anoxic / oxic transition zone (Sarradin et al. 2009). Our data also stress that the isotopic composition of some
dominant macrofaunal species vary at the scale of a single structure (de Busseroles et al. accepted with
revisions), highlighting the complexity of the trophic chain (Colaço et al, 2002). Overall, the food web structure
of the Tour Eiffel hydrothermal edifice shows small-scale variations that can be attributable to variations in local
food source availability, to environmental conditions or to specific feeding strategies. A strong relationship was
observed between δ13C and δ15N isotope signatures and environmental conditions for certain species (B.
azoricus, B. seepensis, Mirocaris fortunata, Protolira valvatoides). Our present working hypothesis is that vent
fluid characteristics influence microbial production at small spatial scales and thus represent key factors in the
variation of local carbon sources at vents (De Busserolles et al. accepted with revisions).
Temporal studies
The temperature and chemical data collected so far at Tour Eiffel suggest that temperature is a good proxi to
describe the chemical conditions (CH4, dissolved Fe, pH, H2S, O2) at the scale of the low temperature vent

habitats. Consequently, temperature measurements were used to assess the short term (the studies carried
out during the Exomar and MoMARETO cruises have not exceeded 5 days) variability of environmental factors
in our twelve sampling units. The results show that temperature variability is different in the different faunal
assemblages. We have also identified common periods of variations between temperature probes deployed in
different sampling units, suggesting an influence of regional (currents, tides) and local (turbulence, vent fluid
flow, etc.) hydrodynamic processes on faunal distribution (Brind’Amour et al. in prep.). Longer time-series are
required to link faunal characteristics with other larger-scale fundamental processes such as tectonics,
seismicity, or volcanic activity.
The dynamics of the fauna and environmental factors at Tour Eiffel were assessed during the MoMARETO
experiment, using the autonomous instrument TEMPO (Sarrazin et al. 2007). TEMPO is a long-term imaging
module using SEAMON technology and equipped with a deep-sea video camera and two LED lights. A
CHEMINI Fe (Vuillemin et al., 2009) in situ analyzer and 3 temperature probes were coupled to the TEMPO
module to monitor environmental changes in parallel to community dynamics. Due to technical difficulties, it has
not been possible to recover TEMPO in 2007 but it was recovered in 2008 during the MoMAR08 cruise. After 2
years, the structure of the module was little affected by corrosion. The lens of the video camera was clean,
validating the efficiency of the antifouling system used. Processing of the data is in progress and will allow us to
refine our sampling strategy for MoMARSAT (acquisition frequency, duration of the video sequences, data
processing, etc.), and to build a robust data treatment protocol especially concerning the video sequences.

Time
The TEMPO module monitored the temporal dynamics
of a mussel assemblage at the base of the Tour Eiffel
edifice during 45 days. Environmental conditions were
acquired simultaneously for a longer period. The module
stayed on the bottom during 2 years.
Temperature and total dissolved iron concentrations measured
in the mussel assemblage. Temperature was monitored during
21 month using a NKE sensor while Fe concentrations were
measured during 6 months with the chemical analyzer
CHEMINI.
For MoMARSAT, our main goal is to acquire longer time-series data to examine the temporal dynamics of
faunal assemblages on the Tour Eiffel edifice, in relation to the variation of environmental factors at three
different spatial scales: local, edifice, and vent field. More specifically, we plan to:
1. assess the variations of faunal assemblages in terms of composition, diversity and density at different
spatial scales (local, edifice, vent field);
2. integrate data from different disciplines into our data base;
3. identify the variations of environmental factors at different spatial scales (local, edifice, vent field);
4. establish the links between faunal variations and environmental factors (conservative or not) at the
different scales considered;
5. identify the factors that significantly affect the structure of faunal assemblages at vents through
multivariate statistics;
6. continue mapping the distribution of faunal assemblages throughout the years on the Tour Eiffel edifice
from 1994 to 2011 (on-going thesis, D. Cuvelier, MARBEF);
Two ecological modules, similar to TEMPO, will be deployed, one being connected to the SEAMON East node
near Tour Eiffel (located in Document 2). The second one will be used for short term moorings (2 to 6 hours of
continuous acquisition). Near real time connection to shore, will allow transmission of a subset of the data
(mainly chemical data), with the possibility to modify sampling rates during the experiment. The bandwidth
limitation of acoustic transmission is not suitable to transmit video imagery. However, the transmission of still
images will be tested at a low frequency. Video will be stored locally to be recovered during MoMARSAT-2011.
Image analyses will permit extraction of biological data on dominant species morphology and size structure,
estimation of minimal density and biomass as well as collection of data on species behaviour (feeding,
predation, movement). Video imagery will also give insights about faunal assemblage variations, succession
patterns, growth of visible species (mussels, shrimps, crabs), behavioural and biological interactions such as
predation (Sarrazin et al., 1997).The sensors installed on the module will permit the measurements of
environmental factors (oxygen and iron concentrations, temperature) within the studied faunal assemblage.

To complete and validate the temporal approach, we will pursue the small–scale characterization of the
different assemblages colonizing the studied edifice and other assemblages of the Lucky Strike vent field (cf.
Thematic packages 1 and 3). The experimental design will rely on the acquisition of time series temperature
data by a network of autonomous temperature probes deployed on selected mussel assemblages. In situ
analysis will be completed by discrete sampling that will allow the acquisition of other important parameters
(dissolved and particulate metal concentrations, methane, organic matter…) to understand the processes
controlling the fluid/seawater mixing zone. The speciation of metallic species and their interaction with organic
matter will be particularly studied. Fluid flow measurements will be added to the database (Sarrazin et al.
submitted). Quantitative sampling of selected faunal patches will validate the data acquired with the video
imagery. These samples will also be used to understand the variation of biochemical composition
(condition/productivity index) of the animal patches in relation to the environmental factors. The temporal
dataset gathered on Tour Eiffel from 1994 on, will be completed with video transects during each cruise
following the Cuvelier et al. (submitted) protocol.
A mooring with a sediment trap and a current meter will also be deployed close to Eiffel Tower to study the
possible influence of the vent fluid on the ocean chemical balance and to tackle the question of the timing of
reproduction in hydrothermal organisms. The composition (species diversity), the temporal fluctuation of larval
production and the flux of the settling hydrothermal particles emitted by this active vent will be examined.
Finally, the characterization, distribution and evolution of the microfauna are an important aim of deep sea
hydrothermal ecosystem studies. Microbiological sampling and experiments with colonization devices have
been carried out at Lucky Strike, most notably during the EXOMAR, GRAVILUCK and MoMAR2008-Leg 1
cruises. For the MoMAR-Demo / MoMARSAT project, we plan to deploy a set of microbial colonization devices
in the immediate vicinity of chemical and temperature sensors, around the Tour Eiffel SEAMON ecology node
(also called east node in location map of Document 2). These devices are deployed by ROV and are simple
boxes containing standard mineral substrates.
3.5 Thematic Package 5: Physical oceanography
Lucky Strike, as most segments of the Mid Atlantic ridge south of the Azores, is a site of active internal wave
generation, as well as complicated local circulation influenced by bathymetry and mixing, both near the central
volcano and elevated rift valley walls, and in the semi-enclosed deep nodal basins. Oceanographic data
collected in 2006 and 2007 during the GRAVILUCK and BB-MoMAR cruises, provide an interesting first view of
the internal waves in the area, the flow between the deep basins, and where mixing takes place, in particular in
the channel to the east of the Lucky Strike volcano. We are lacking information closer to the volcano summit,
which would stride a longer period.
We plan to equip the surface BOREL buoy mooring of the SEAMON infrastructure both with a GPS, and with a
set of T° (and P) autonomous probes, recording at relatively high frequency (1 minute). This data set will also
be used for geodesy (see § 3.2). Current measurements at lower frequency (30') will be an important
complement. We will use current meter data which are being recorded near NERIES BBOBS1 (see localisation
in Document 2) in view of cleaning seismic data from noise associated with baroclinic tides.
We also plan to document the local time variation of water flow patterns and the fluid exchange between the
seafloor and the water column close to the Tour Eiffel ecology node. An autonomous CTD/ADCP instrument
package has been assembled to that purpose during the EXOCET/D project. This system was deployed and
validated for 3 days in 2006 during the MOMARETO cruise. We plan to upgrade this system for autonomous
deployment over a longer period (6-12 months). This will involve extending the capability of the existing data
logger, augmenting the energy supply, and improving the synchronization between the CTD and the ADCP. A
new mechanical frame will be designed that allows for free flushing of the CTD sensors, an open range of the
acoustic transducers of the ADCP while all systems being well protected during the deployment and recovery
phase. Special care will also be taken in regard to corrosion and biofouling issues.
Finally, we plan to complement the dataset recovered during the GRAVILUCK cruise concerning the spatial
distribution of mixing over the water column and in the horizontal in the Lucky Strike segment. For this, we will
perform fine scale measurements of hydrology and currents (vertical resolution of 1m for hydrology and 8m for
currents), and microstructure measurements (i.e. vertical resolution of cm-mm). We plan to use the
microstructure profiler VMP6000, and a rosette with CTD sensors and one LADCP. Our main purpose will be to
characterize mixing induced by internal tides (the main component of the internal wave field). To this aim we
plan to perform repeated profiles at fixed point stations over half a tidal cycle (at least 6h).
Section 4: Observatory infrastructure and data management
The MoMAR-D experimental design combines autonomous instruments which will store data over the duration
of the mission (1 year), and instruments that will be connected to shore via the SEAMON (Sea Monitoring
Node) system (Blandin J. & Rolin J.F., 2005).

4.1 The SEAMON / BOREL technology
The SEAMON system includes a set of long-term, non-cabled sub-sea observatory components, initially
developed by Ifremer during the EU ASSEM project (2002-2004), which have since been upgraded and made
more reliable. SEAMON is the generic name of the seabed stations serving a local set of sensors, whereas
BOREL (Bouée relais) is the surface data transmission relay. The SEAMON stations are rated for 4000 mwd
operations. Each one can provide 8 kWh, allowing for the sensors operation and for a daily data transmission of
ca. 40 kbytes. You will find a table of connected instruments with indications of the volumes of transmitted data
and energy requirements in Document 2.
The main components of SEAMON are the following:
COSTOF (Communication and Storage Front-end). This electronic unit serves a set of local sensors by
providing them with data storage, communication channels and optionally energy. COSTOF communicates with
the ROV via CLSI (see below), and with a ship, and the BOREL buoy via acoustic modems. The COSTOF
robustness and modularity rely on the use of a low power field bus (CAN) linking a set of simple identical
boards, each board devoted to one sensor. The measurement sequencing is left to each sensor. This way, a
COSTOF failure does not prevent data acquisition at the sensor level. Conversely, data duplication at the
COSTOF level is a safety factor in case of sensor damage.
CLSI (Contact-Less Serial Interface) is a small device made of two halves, allowing serial communication
between two units, without electrical connection. If one half is connected to a ROV, and the other half to the
COSTOF, communication can be established between the ship and any connected sensor. It is very useful just
after the ROV has completed a sensor mechanical installation, to check or fine tune its functioning before the
ROV leaves the area.
BOREL
The BOREL buoy is the data transmission relay between the SEAMON stations and the Iridium satellite
constellation. It is moored within acoustic range of the SEAMON stations and is composed of two identical
independent data transmission channels. Channel 2 can be activated from shore in case of a failure of channel
1. Each data transmission channel is powered independently and comprises an acoustic modem, a control
electronics and an Iridium modem. The communication is bi-directional and BOREL supports three data
transmission modes: periodic (typical rate 6 hours), triggered by events detected on the seabed, and triggered
from shore. BOREL has now been used for two years in the Mediterranean Sea, where it is moored at 2000 m
depth. The Mediterranean mooring will be modified for MoMAR-D to take into account the sea conditions
prevailing in the mid-Atlantic. Its position and the local sea/wind state will be monitored throughout the
experiment. The robustness of this mooring is clearly one of the technical challenges of the MoMAR-D
experiment.
Acoustic data transmissions
For five years now, successive SEAMON/BOREL systems have been using the same type of acoustic
modems. Their reliability has now reached a satisfying level, but their energy requirement per transmitted bit (a
key parameter for non-cabled observatories) can probably be significantly lowered. Ifremer is currently working
on this issue. This work started in 2007 with a selection of five modems available on the world market. Among
the selection criteria, the lowest energy necessary to transmit 1 bit at a given distance was sought. In 2008,
three of these five modems were tested at sea, between a sub-sea station at a depth of 2200 m, and the R/V
L’Europe. This test demonstrated that the latest modems require at least 15 times less energy to transmit one
bit in those conditions, than the ones used on SEAMON until now. Longer term tests of the two best modems
are planned in 2009, between the 2200 m-deep subsea station and a relay buoy. The MoMARSAT experiment
will directly benefit from these improvements.
4.2 Configuration of the nodes
Two SEAMON nodes will be deployed in the Lucky Strike vent field (see location in Document 2). A Table of
the connected sensors, the volume of data transmitted an dthe energy required for transmission at each node
is provides in Document 3:
• SEAMON-East will be primarily devoted to thematic experiments 3 (Chemical fluxes), 4 (Ecology) and
5 (Physical oceanography). It will connect a video camera, chemical sensors and the CTD/ADCP
package. T-probes connected to this station will also provide time-series data for experiment 1
(Seismicity and hydrothermal activity). This node will be moored at the base of the active hydrothermal
edifice Tour Eiffel, near the location of the autonomous TEMPO station deployed during the
MoMARETO cruise.
• SEAMON-West will be primarily devoted to thematic experiments 1 (Seismicity and hydrothermal
activity) and 2 (Seafloor deformation). It will connect the pressure probe, one OBS, and the OBM. This
second node will be moored in the western part of the lava lake, near the present location of the
pressure probe installed since 2006.

Sketch of the MoMAR-D experiment
The BOREL buoy
The MoMAR-D project includes pre-cruise integration of these sensors to the monitoring node, followed by their
qualification and validation prior their deployment during one year.
Underwater connection devices
The sensors to be connected underwater will use a low cost connection device (CdC,) specially developed and
validated during the ASSEM project.
Data storage
Each connected sensor will also independantly store data over the 12 months duration of the project. The
Ecology package (TEMPO) and the pressure gauge already have tested operational SEAMON connections.
Development will be carried out for the connected OBS (IPGP), the OBM (Univ. Bremen), the NOC continuous
fluid flow analyzer and the CTD/ADCP mooring. Other sensors will be deployed as autonomous instruments,
storing data that will be recovered at the end of the 1 year experiment. The table in section 4.4 presents a list of
the sensor to be implemented during the cruise.
Biofouling
Biofouling is a major issue in the vent ecosystem. Biofilms form on every available surfaces and trap the
mineral particles emitted by the hot fluids. The method used successfully (Exomar, 2005 and MoMARETO,
2006) for preventing bio-fouling on the lens of the TEMPO video camera and on an Aanderaa oxygen optode
relies on localized microchloration. This method does not modify the image, and the concentrations of
chemicals released are negligible.
Feasability
The SEAMON system has been deployed previously in the following sea-bed monitoring applications:
• 2004, Gulf of Corinth, 380 m, 7 months, seismicity, geodesy - Ballu et al., gas emissions (CH4, O2),
• 2004, Finneidfjord (Norway), 25 m, 4 months, slope stability - Strout et al. (pore pressure, T°C), gas
emissions (CH4),
• 2005-2007, Var canyon, 2000 m, 24 months, particle dynamics - Khripounoff et al. (dissolved O2,
turbidity, current),
• 2006, Bay of Douarnenez, 25 m, 2 months, experimental polluting shipwreck monitoring – Marvaldi et

Feasibility of MoMAR-D and MoMARSAT also depends on the availability of ships, ROVs, on access to
supporting shore-based infrastructures, and on additional funding from national agencies. The strong support
received at the regional level is an asset of the project, allowing us access to facilities in the Azores, such as a
GPS station at the University of the Azores for differential GPS location, and, most notably, the facilities in Faial
Island. LabHorta is a laboratory facility that expands the capacity of research cruises for the experimental
studies of the biology, physiology and behaviour of deep-sea hydrothermal vent fauna. The University of the
Azores also maintains an Oceanographic instrumentation and Calibration Laboratory, which is dedicated to
insure the operationality and precision of several types of oceanographic equipments. Last but not least, 2

research vessels are based in the islands and could allow a quick response to an event occurring at Lucky
Strike during the 12 month of the observatory deployment.
4.3. Data management and scientific integration
Data management and dissemination is a key task in the implementation of a multidisciplinary long term
observatory. Principles of data management and dissemination will be discussed within the MoMAR-D project
in the spring of 2009, to obtain a formal participant agreement. The data management policy and procedure will
be defined taking benefit of the experience gained by Neptune Canada. The principles to be specified are: i) the
definition of the data to be acquired, ii) the procedures of control for these data and the definition of metadata in
accordance with the standards recommendations on data documentation, and finally iii) the dissemination level.
The framework for this discussion is defined in the ESONET Description of Work. Data management
procedures will be fully compatible with international recommendations and standards in order to improve
interoperability with other systems and to ease comparison with other datasets: ISO standards for metadata,
COI/WMO standards for quality flag scale.
SISMER will collect, flag and archive the data (in real time and after the recovery). Data will be made available
online according to ESONET data policy and European directives. Data will also be forwarded to data centers
involved in the ESONET project in order to be permanently archived and distributed.
The MoMARSAT cruises will also produce data from autonomous sensors or complementary site studies.
These data will be archived and part of the demonstration will be to design appropriate procedures for control
and dissemination of these data. Biological site survey data acquired during the cruises will be available
through the BIOCEAN database.
A GIS database and interface is being implemented for the MoMAR sites with support from the ANR
Mohtesiem (J. Escartin), and MoMARnet projects. It now contains all the available dive data and a subsequent
subset of the geophysical data collected so far in the MoMAR area. It will be maintained by the MoMAR-Demo
project and adapted to fit the ESONET policy on data property and accessibility.
An important task will be to develop links between the MoMAR-Demo data management system, and the data
management systems currently used for volcanic and seismic monitoring, and for ecosystem inventory and
surveillance, at and near the Azores Islands. To this aim, we have secured the participation (to MoMAR-Demo,
not involved in actual MoMARSAT cruise work) of colleagues from the Centro de Vulcanologia e Avaliação de
Riscos Geológicos, and from the Department of Oceanography and Fisheries of the University of the Azores.
Scientific integration of the data is a key point of this project. Data treatment will be done first at the Thematic
package level, followed by a second step to understand the links and common sources of variability at the
different scales studied. Data coming from all thematic packages will be analyzed to study the links between
environmental changes and community structure and dynamics. This final data integration step will be the
subject of a workshop, gathering all scientists involved in the MoMAR-D proposal.
The Table below lists the data and sample sets which we plan to acquire, their timing of acquisition, the
relevant thematic packages, and the corresponding tools or sensors. Instruments which we plan to connect to
SEAMON are listed in bold. Those which will require some adaptation prior to the cruise are listed as
“prototypes”.

Treatment of collected data sets will be conducted in two stages: in near real time for the subset of data
transmitted through the SEAMON system; and after the 12 months of the demonstration for the whole data set.
The near real time data will serve both as support for scientific interpretation, and as an indicator that an “event”
is occurring. Events at Lucky Strike may be volcanic (eruption, underground dyking event, or rapid degassing of
the magma chamber), tectonic (displacement along axial faults), or hydrothermal. Understanding the impact of
these events on biological communities (micro organism bloom, composition, structure,) is one of our key
objectives.
Our array of connected sensors will be able to detect all, or most of these events. Rapid response is particularly
indicated in the case of a volcanic event, as it has been shown to profoundly modify vent ecosystems, with a
variability of hours, days, and weeks (Haymon et al., 1993; Shank et al., 1998), probably extending to years.
Our rapid response capability at Lucky Strike will be limited, but enough to open exciting opportunities: 1- the
SEAMON capability for interrogating sensors and modifying certain parameters from shore shall allow us to
modify data sampling rates for a given sensor, if an event is detected; 2- we also plan to take advantage of the
access to the Azores-based RV Archipelago, which unfortunately does not allow for ROV-type intervention, but
can perform water column sampling, and recover acoustically released devices; 3- finally, should evidence for a
major event be collected, we will actively search for a larger ship of opportunity, with ROV capability (for
example the new ROV-equipped Portuguese).
4.4. A regional managing strategy for the Azores node
The growing interest and the increased number of science activities at the MoMAR vent fields have led the
Portuguese and Regional administration to propose, in 2006, the area as a Marine Protected Area (MPA) within
the OSPAR network. This proposal followed a workshop organized in Horta in 2002 (Santos et al, 2003). The
Lucky Strike vent field is identified in the MPA proposal «with the aim of promoting knowledge, monitoring and
conservation of an area that best represents species, habitats and ecological processes in deep-sea
hydrothermal vents in the OSPAR area, while enabling sustainable scientific research and promoting education
and environmental public awareness and interest ».
MoMAR-Demo will undertake to comply with the MPA rules and develop a coherent experimental site
management plan. This plan will include a set of rules for PI’s, based on the MPA code of conduct and on the
InterRidge code of conduct. These rules will aim at minimizing the impact of research on the environment, and
at ensuring the compatibility of all the experiments planned. In this context, we plan to devote one MoMARSAT
dive in 2011 to clean the area around our experimental network of the abundant non-native material left over
the years of scientific work. Acquired video imagery data will be used as the background of the site
management objective.
MoMAR-Demo will for the greater part be financed by the participating institutions and their respective national
funding agencies. This partnership, together with the Portuguese maritime authorities, MPA authorities, and the
Regional Government of the Azores, will form the embryo for the future Regional Legal Entity of the ESONET
Azores node.
Section 5: Public outreach
Near real time transmission of data (and video images) from the Lucky Strike vents will open new opportunities
for public outreach. Our plan for the MoMAR-Demo is to fully use these opportunities, both in the direction of
the general public, and toward school and university students. The dissemination plan will be designed at the
beginning of the project in collaboration with the dedicated ESONET Workpackage. It will cover international to
75

76
76
regional initiatives such as the production of a didactic kit, in Portuguese, on hydrothermal vents and seafloor
observatories for the different school levels, in connection with in the Azores University.
Taking advantage of the contacts made in 2006 with the GRAVILUCK and MoMARETO cruises, we will also
start a collaborative project with the European Aquarium Network. The public outreach strategy for the MoMAR
project will be designed in close collaboration with Oceanopolis, with the Public Relation Offices of Ifremer,
CNRS, NOC and the other participating institutions. This strategy includes press conferences before the
cruises, maintenance of a cruise web site, and organization of a live event from the vessel, with video
conferences and transmission of live images from the seafloor such as the nuit des abysses done during
MoMARETO (Sarrazin et al.). We also will seek the participation of journalists interested in making a movie out
of this seafloor observatory adventure. The project web site will allow an access to the “real time” data edited
and commented by scientists. Our plan is to have an exhibit, which will last over the 12 months of the MoMARDemo, with access to the most recent data and images from the seafloor, at the Oceanopolis aquarium in
Brest. Mirror sites and exhibit material could also be set in other large aquariums in Europe.
Section 6: Workplan
Due to weather constraints, submersible cruises to the MoMAR area can only take place in the summer (May to
August). Deployment is planned for the summer of 2010, which will leave us time to achieve the physical
integration of the sensors on the SEAMON nodes. To comply with ESONET need for visible results prior to the
end of 2010, we have defined the MoMAR-D work plan with a core period (January 2009 to December 2010)
after which we will report on all technological and integration aspects, as well as on the test of the system at
sea during the first MoMARSAT cruise. We will then produce an updated final report in December 2011, after
the MoMARSAT–2 cruise, integrating the full results of 1 year operation of the system.
Seven Milestones have been identified throughout the MoMAR-D project, corresponding to crucial steps:
submission of the cruise proposal (M1), agreement on a data management policy (M2), on shore integration
and trials (M3), system deployment (M4), intermediate report to ESONET (M5), system recovery (M6), final
report (M7).

Section 7: Synergies with European and national funded initiatives.
The ESONET project has provided the framework for the MoMAR-Demo project within its internal call on
Demonstration mission. The MoMARSAT cruises are proposed to carry out MoMAR-D.
This proposal builds upon over 10 years of work on hydrothermal systems of the Azores area, much of which
was achieved with combined European and national funding. Two EC-FP6 projects directly concerned MoMAR:
one for development of observatory sensors (EXOCET/D; Sarradin et al., 2007) has provided support for the
MoMARETO cruise and the deployment of the TEMPO SEAMON module at Lucky Strike; the other is a
research and training EC network that funded 13 PhD and 3 post docs for MoMAR research (MoMARnet;
Cannat et al., 2006).
A more recently funded FP6 project, NERIES, funds the installation for 3 years of the broadband Ocean Bottom
Seismometer near Lucky Strike (part of BBMoMAR project; W. Crawford and S. Singh). More recently, the
SENSEnet Marie Curie Research network, coordinated by D. Connelly and focused on sensor development for
deep sea hydrothermal environments, has been selected for funding and is now in negociation stage with the
EC. This project will support students and researchers involved particularly in Thematic Package 3 of MoMARDemo.

National funded initiatives in the MoMAR “chantier” have mostly been French so far (Ifremer, INSU, ANR), with
a significant Portuguese contribution (the Marine Protected Areas initiative, the Lab-Horta biological facility),
and UK involvement in Electro-Magnetic site surveys at MoMAR vents. Scientific and technological discussions
within EXOCET-D and MoMARnet, and during the initial stages of ESONET, have strengthened this UK
participation (attracting new partners for fluid chemical studies), and have allowed us to find German partners
for the geodetic aspects of MoMAR-D.
Part of the MoMARSAT experiments will be funded through the DEEP OASES project (Thematic package 4, D.
Desbruyères). The project is supported by the Ifremer programs « Ressources minérales, énergétiques et
écosystèmes profonds” (L. Lemoine), and by the GDR ECCHIS. It is also supported by INSU through the
MoMAR chantier, and the “Soutien campagnes” for travel and freight expenses. Part of the MoMAR-D project
(Thematic package 4) was submitted to the FP7 call ENV.2008.2.2.1.2. Deep-Sea ecosystems within a
proposal linked to the actual HERMES project (HERMIONE, PI P. Weaver, contract signature).
An important aspect of the MoMAR-D project is to develop interoperability of sensors and data management
solutions, within ESONET and internationally. For this last aspect, we will take advantage of the opportunities
offered through the Memorandum of Understanding that links Ifremer and the Univ. of VICTORIA, the leading
institution behind the VENUS cabled observatory and the NEPTUNE Canada seafloor observatory initiative. An
observing module called TEMPO mini was connected to the Venus coastal network in the autumn 2008 and will
be recovered in February 2009. After this first coastal trial allowing to validate the instruments and the
interfaces with the cable, the module will be moored at the Endeavour hydrothermal node of NEPTUNE in
Summer 2009 as a part of an integrated multidisciplinary study (contact Mairi Best mmrbest@uvic.ca). Our
technical objective is to learn from the larger Neptune initiative, and our scientific goal is to compare the
temporal dynamics of hydrothermal fauna assemblages between a slow spreading ridge (Lucky Strike), and an
intermediate spreading ridge (Endeavour segment of the Juan de Fuca ridge).

DESCRIPTIF DES CAMPAGNES 2010 et 2011
1- Infrastructure et déroulement du projet
Les objectifs des campagnes MOMARSAT peuvent être résumés ainsi :
- Etude temporelle des processus actifs sur le site hydrothermal Lucky Strike,
- Déploiement d’un observatoire multidisciplinaire non câblé pourvu d’un système de transmission de
données quasi-temps réel,
- Opération de cet observatoire pendant douze mois.
Pour répondre à ces objectifs, le projet MOMAR-Demo est structuré en plusieurs tâches sur une durée de 36
mois (voir tableau en Section 6 du Document 1). Les campagnes à la mer en 2010 et 2011 correspondent aux
phases de mise en place et de récupération de l’observatoire et à l’acquisition de données complémentaires
sur site. Le projet est financé partiellement dans le cadre du WP4 « Missions de démonstration » du réseau
d’excellence ESONET (MoMAR-Demo, A. Colaço et P.M. Sarradin ; voir détail du plan de distribution des
fonds alloués par ESONET dans la Fiche Synthétique 2).
MoMARSAT repose sur un parc de matériel en grande partie existant (Cf Tableau du Document 1 § 4.3). Le
réseau d’observation utilise le système SEAMON – BOREL et les capteurs associés. L’année 2009 sera
consacrée à l’adaptation des stations et des capteurs et à leur qualification. A partir des données de
bathycélérimètrie disponibles sur la zone, une étude de propagation acoustique du site sera effectuée, étude
qui déterminera la position optimale de la bouée par rapport aux stations. L’intégration du système dans sa
totalité (y compris la gestion des données) et les tests d’endurance à terre auront lieu au second semestre
2009. En parallèle, la politique de mise à disposition et de traitement des données sera définie et acceptée par
tous les participants au projet. La tâche « communication vers le grand public » suivra un calendrier analogue,
aux échelles nationale et européenne.
Afin de valider, et de valoriser les séries temporelles, il sera nécessaire de disposer d’une part de mesures
ponctuelles des mêmes paramètres sur une zone plus large, et d’autre part de mesures ponctuelles de
paramètres qu’on ne sait pas mesurer sur le long terme. Ces mesures ponctuelles sont indispensables pour
les expériences sur l’écologie, sur la chimie des fluides, et sur la géodésie. Pour l’écologie, l’acquisition de
données sur site sera focalisée sur Tour Eiffel et aura lieu pendant les 2 campagnes MOMARSAT. Pour la
chimie des fluides, l’échantillonnage concernera plusieurs sites sur tout le champ hydrothermal et débutera en
2009 durant Bathyluck afin d’obtenir une série sur 3 ans. Pour la géodésie, nous prévoyons une seconde
campagne de mesure du réseau de repères (voir Figure en fin de Document 2) en 2011.
Nous privilégierons les plongées longues (≥ 24 h), permettant de couvrir les objectifs de plusieurs manips, sauf
pour les premières plongées de mises en place du dispositif SEAMON en 2010, qui doivent être rapidement
suivies de tests. Nous utiliserons si nécessaire la navette ascenseur et nous organiserons le planning de ces
plongées pour que les échantillons fragiles (biologie en particulier) soient prélevés peu de temps avant la
remontée.
2- Campagne 2010
La première campagne du projet en 2010 permettra la mise en place de l’infrastructure de l’observatoire
(bouée BOREL et nœuds SEAMON) et des capteurs connectés (environ 6 jours). Cette mise en place sera
précédée d’une reconnaissance rapide et du marquage des zones à instrumenter (1 jour). La récupération et le
redéploiement de l’instrumentation autonome qui aura été mouillée durant la campagne Bathyluck 2009
prendra environ 6 jours: récupération et redéploiement de 2 jauges de pression, des colonisateurs microbiens,
et du réseau de capteurs autonomes de T° des fluides sur 5 sites hydrothermaux du champ Lucky Strike (Y3,
Statue of Liberty, Tour Eiffel and Nuno-Hélène ; cf Figure en fin de Document 2). Environ huit jours seront en
outre nécessaires pour l’acquisition de données d’écologie et de chimie des fluides afin de valider les séries
temporelles et de les situer dans un contexte plus général. Enfin, les temps de reconditionnement du ROV
entre les plongées seront consacrés à des opérations de pont : récupération et redéployement de 10 OBS (4
INSU, 5 portuguais, 1 BBOBS-IPGP), et manips d’océanographie physique.
Les opérations à mener durant la campagne MoMARSAT 2010 sont donc les suivantes :
1. Reconnaissance rapide et marquage des zones à instrumenter
2. Mouillage des Nœuds (free falling + déplacement par VICTOR) et de la bouée BOREL, mise
en place des capteurs connectés à Seamon, tests de fonctionnement, maintenance éventuelle
3. Acquisition de données sur sites (chimie, écologie)
4. Déploiement des capteurs autonomes
5. Travaux de surface

2-1 Reconnaissance du champ, choix et marquage des zones à instrumenter
Les données de microbathymétrie et les mosaiques photos acquises sur le site avec le Module de Mesures en
Route du ROV VICTOR durant les campagnes MoMARETO et MoMAR2008-Leg1 (Cartes en fin de document
2) permettent une navigation et une recherche des cibles très rapides. Les zones à instrumenter (Tour Eiffel,
sites Est et Nord Ouest, lac de lave) seront repérées par des marqueurs passifs. L’étude de propagation
acoustique sera validée sur site. Une reconnaissance petite échelle de l’édifice Tour Eiffel sera ensuite
effectuée suivant le protocole développé par Cuvelier et al, (soumis, DSR). Cette reconnaissance permettra de
marquer les zones d’études et d’acquérir la donnée vidéo nécessaire à l’étude temporelle de l’édifice
(Thematic package 4). L’ ensemble de cette reconnaissance prendra 24h (1ère plongée).
2-2 Mouillage des Nœuds et de la bouée.
L’infrastructure du réseau sera mouillée immédiatement après la plongée de reconnaissance. Les nœuds
seront mouillés en « free falling » depuis le navire. Le mouillage comprend un lest de descente, une flottabilité
additionnelle et une balise/ largueur BUC. Sur le fond (Plongée 2), les mouillages seront déployés et
positionnés par le submersible. La durée approximative pour le mouillage est de 2 h pour chaque nœud. Le
positionnement sur le fond de chaque nœud par Victor durera entre 4 et 6 heures. Le mouillage Borel
comprend un lest de 1600 kg, une ligne de mouillage de 1700 m (Polypropylène, Nylon) et la bouée équipée
(1300kg, diamètre 2.3 m). La stratégie de mouillage comprend la mise à l’eau de la bouée à 2000 m du point,
le filage de la ligne de mouillage en remontant au-delà du point, et le largage du lest. La durée estimée de mise
en place de la bouée est de 6 h. Le mouillage de la bouée sera effectué après la seconde plongée, durant le
reconditionnement de Victor.
2-3 Mise en place des capteurs connectés à SEAMON,
Une contrainte technique importante réside dans le déploiement des capteurs par Victor et leur connexion aux
nœuds SEAMON (Nœud Est « écologie », Nœud Ouest « géophysique » ; cartes en fin de Document 2 et liste
des capteurs à connecter dans le tableau du § 2.8 de ce Document). Cette opération a déjà été réalisée par le
submersible habité Thetys (HCMR) en 2004 dans le Golfe de Corinthe. L’étape préalable de reconnaissance et
de marquage des zones à instrumenter est déterminante pour la mise en place des capteurs sur ces sites à
topographie très perturbée. Pour faciliter le déploiement, certains capteurs pourront être connectés à leur
nœud d’accueil sur le fond en utilisant des connecteurs CdC. La durée de mise en place de chaque capteur
par le ROV a été estimée entre 3 et 4h, soit environ 12h pour le nœud Ouest (3 capteurs, tableau au § 2.8) et
20h pour le nœud Est (Plongée 3).
Les tests conduits pendant cette phase de déploiement du dispositif pourront conduire à récupérer tout ou
partie du système pour réparation ou remplacement. Ceci pourrait dans le pire des cas représenter 2 plongées
supplémentaires (environ 56h). Nous prenons un pied de pilote intermédiaire de 28h (Plongée 4 et
reconditionnement ROV), étant entendu que le fonctionnement du système SEAMON a déjà été testé à de
nombreuses reprises (cf § 4.2 du Document 1).
2-3-1 Ecologie : Tempo, précurseur du Nœud écologie, a été mouillé pendant la campagne MoMARETO.
Tempo est constitué de 2 modules : le module énergie rassemblant les composants SEAMON et le module
capteurs relié par un câble de 15 m. Lors du mouillage, le module capteur est logé dans le module énergie.
Victor positionne le module énergie sur le fond à proximité de la zone d’étude. Il déploie ensuite le module
capteurs à portée optique de l’assemblage cible. Les paramètres de la caméra (cadrage, zoom et focus) sont
réglés depuis la surface à l’aide d’un lien CLSI. Finalement, la canule de prélèvement de l’analyseur in situ,
associée à 3 sondes de températures autonomes et une optode à oxygène, est mise en place dans
l’assemblage. Le bon fonctionnement de l’ensemble est vérifié sur place via le lien CLSI.
2-3-2 Etude des flux chimiques : Le module CTD/ADCP et le capteur Fe / Mn, seront connectés sur le fond au
Nœud Est. Le module CTD/ADCP sera positionné à la base de Tour Eiffel, l’analyseur de Fe/Mn sur une
émission diffuse à proximité du module TEMPO.
2-3-3 Sismicité.
Le dispositif comprendra un OBS 3 composantes acquis pour l’opération, modifié pour être manipulable par le
ROV (suppression de la flottabilité et montage d’une poignée adaptée), et pour être connecté au nœud
SEAMON Ouest (l’enregistrement autonome des données sera conservé, un second processeur de type
Persistor prendra en charge l’interface avec SEAMON).
2-3-4 Géodésie : La jauge de pression JPP2 est opérationnelle sur le site en mode autonome depuis l’été 2006
(campagne GRAVILUCK). En 2008 l’instrument a été remplacé dans un conditionnement différent, mais la
jauge reste similaire à celle utilisée pendant la démonstration ASSEM dans le Golfe de Corinthe. Nous
disposons donc de la technologie pour la connecter au nœud SEAMON. Le capteur autonome sera récupéré,
et un capteur modifié sera déployé puis connecté.
2-3-5 Procédure de récupération des nœuds

En cas de dysfonctionnement constaté lors des premiers tests sur les nœuds, ceux ci pourront être récupérés
assez rapidement en utilisant la navette ascenseur NASA. Celle-ci a une capacité d’emport de 170 kg dans
l’eau, suffisante pour remonter un nœud SEAMON.
2-4 Acquisition de données sur sites
2-4-1 Ecologie : L’objectif principal du nœud « écologie » est la surveillance d’un assemblage dominé par la
modiole B. azoricus. Afin de compléter et de valider l’approche temporelle, nous poursuivrons la caractérisation
à petite échelle des différents assemblages colonisant l’édifice Tour Eiffel. Ceci permettra de multiplier le
nombre d’unités d’échantillonnage et donc, d’élargir l’échelle spatiale de notre étude ainsi que d’obtenir des
données à des intervalles annuels. La stratégie, utilisée lors de la campagne MoMARETO, repose sur la mise
en place d’une série de sondes de température autonomes sur différents assemblages. En 2010, 12 unités
d’échantillonnage seront ainsi caractérisées (chimie, physique, biologie « imagerie ») et instrumentées par 24
sondes de température autonomes (poursuite du plan d’échantillonnage amorcé au cours des campagnes
Exomar et Momareto). En 2011, ces unités seront de nouveau caractérisées (chimie, physique, imagerie) et la
faune prélevée de façon quantitative. Idéalement, cette étude de dynamique temporelle des assemblages sur
la zone Lucky Strike sera poursuivie pendant plusieurs années et appliquée à d’autres structures géologiques
(extension de l’échelle spatiale). L’environnement physico-chimique sera caractérisé par 2 méthodes
complémentaires en utilisant une instrumentation spécifique développée durant le projet EXOCET/D (Sarradin
et al IR News 2007). L’analyseur in situ CHEMINI (Vuillemin et al. 2009) permettra de mesurer les
concentrations en sulfure total (Sarradin et al., 1999) et FeII (Sarradin et al 2005) à) proximité des organismes.
Deux électrodes Unisense, intégrées au circuit, permettront également de mesurer le pH et l’oxygène. Le
préleveur d’eau PEPITO permettra de prélever des échantillons pour compléter la caractérisation du milieu
(métaux [Riso et al, 1997, Sarradin et al. 2009] et matière organique dissous et particulaires, radioéléments,
méthane). Le capteur de débit sera déployé pour caractériser la vitesse des émissions sur l’assemblage cible
(Sarrazin et al, submitted).
L’utilisation d’un second module vidéo miniature en cours de développement permettra l’acquisition de
séquences vidéo continues de 2 à 6h (associées à des mesures de température) afin d’évaluer la dynamique
temporelle de différents assemblages et leur variabilité haute fréquence. L’aspect long terme sera pris en
compte par le module vidéo connecté à SEAMON (3 min de vidéo par jour durant 12 mois).
Le prélèvement “quantitatif” de faune, associant prélèvement à la pince et à l’aspirateur à faune sur des
surfaces définies, permettra de valider les données acquises par les methodes d’imagerie. Un système de
prélèvement quantitatif sur substrat dur est en cours d’étude à Ifremer.
Les données obtenues seront traitées par des analyses statistiques multivariées, en collaboration avec Pierre
Legendre (Université de Montréal). Ce plan d’échantillonnage sera mis en œuvre sur d’autres assemblages
chimiosynthétiques profonds, que ce soit en zone hydrothermale (campagne BIG) ou en zone de fluides froids
(campagnes MEDECO et WACS).
2-4-2 Chimie des fluides. L’échantillonnage des fluides chauds sera réalisé sur la dizaine de sites équipés de
capteurs de température autonomes dans le cadre du thème 1 (Sismicité et dynamique du système
hydrothermal ; cf Document 1). On prélèvera également des fluides diffus sur le site « écologie »
L’échantillonnage sera conduit en utilisant les seringues titane et le PEP de Victor (et ou PEPITO). Les
échantillons seront analysés à bord (alcalinité, pH, oxygène, sulfure et CH4) ou acidifiés et stockés dans des
flacons LDPE pour analyses à terre. La composition chimique des fluides prélevés (fluides diffus et fluides
haute température) sera déterminée : éléments majeurs et traces, compositions isotopiques (isotopes stables
et radiogéniques). Cette opération sera répétée en 2011.
2-5- Déploiement des capteurs autonomes
Des sondes de température autonomes seront mises en place dans les sorties de fluides d’une dizaine de
sites répartis sur le champ hydrothermal de Lucky Strike. Ce dispositif reproduira celui de la campagne
BATHYLUCK 2009.
Des modules dédiés à l’étude de la colonisation par les microorganismes seront installés à proximité
immédiate des deux sites SEAMON. Ces modules sont constitués de plusieurs tubes avec des substrats
minéraux ou organiques différents.
L’utilisation d’un système de mesure de la température par fibre optique (Fiber Bragg grating) sera testée
durant la campagne sur une zone d’émissions diffuses proche du site de Tour Eiffel.
2-6- Travaux de surface
Les périodes de reconditionnement de Victor (8 heures entre chaque plongée) seront mises à profit pour
effectuer les récupérations et mouillages (Nœuds SEAMON, bouées BOREL, Piège à particules, OBSs) mais
également pour effectuer des profils CTD / Rosette et de microprofileur VPM6000 au dessus du volcan de
Lucky Strike, afin de mieux contraindre la structure de la colonne d’eau au cours de la campagne. Le réseau
de surveillance sismique local constitué de 4 OBS du réseau national INSU et de 5 OBSs portuguais, sera
déployé sur les flancs du volcan de Lucky Strike selon la configuration la plus adaptée (cf légende de la Figure
en fin de document 2).

Par ailleurs, on installera en surface, sur la bouée BOREL, un GPS permettant de suivre les variations de
hauteur d’eau. Ces variations serviront à extraire le signal géodésique des données du capteur de pression. Le
signal de ce GPS sera analysé en utilisant un GPS de référence à terre, installé à Faial et maintenu pendant
toute la durée de l’expérience (1 an) par nos collaborateurs de l’Université de Lisbonne.
Enfin, le câble de la bouée BOREL sera équipé de 10 à 15 capteurs de température (ou T-P) autonomes,
capables d’un enregistrement par minute pendant 1 an. Ces capteurs permettront de suivre l’évolution de la
colonne d’eau, avec des objectifs d’océanographie physique (ondes internes). L’intégration de ces données de
température avec les données GPS sur la hauteur de la colonne d’eau permettra aussi d’interpréter les
données du capteur de pression en termes de déplacements du sol.
2-8 Calendrier prévisionnel de la campagne 2010
L’organisation de la campagne prendra en compte l’expérience acquise durant la campagne Medeco avec
notamment l’utilisation de plusieurs ascenseurs au cours d’une même plongée. Ceci nous permettra de
programmer des plongées d’une durée moyenne supérieure à 24h. Le programme ci-dessous prévoit une
durée uniforme de 24h et est indicatif. Il sera affiné au cours du projet puis validé avec Genavir pour tenir
compte des contraintes opérationnelles.
Nous avons inséré une marge pour nous permettre de récupérer et remouiller des instruments défaillants. En
cas de bon fonctionnement, ce temps de travail pourra être utilisé pour des prélèvements et mesures
complémentaires (fluides, écologie) et pour des prélèvements de modioles sur le site Menez Gwen pour le
projet BioBaz. Ce projet a pour objectif la compréhension des relations de Bathymodiolus avec ses symbiontes
et son environnement dans trois champs hydrothermaux du chantier MoMAR (Menez Gwen, Lucky Strike et
Rainbow). Une demande de campagne BIOBAZ est soumise par F . Lallier pour 2011. Pendant MoMARSAT,
les échantillons de modioles pourront être récupérés par J. Sarrazin, A. Colaço et P.M. Sarradin, également
impliqués dans BioBaz.

3- La campagne de 2011 (22 jours sur zone) est prévue pour la récupération de tous les instruments et de
l’infrastructure au terme de la démonstration ESONET. Cependant, dans la mesure où l’objectif de
MoMARSAT est de pérenniser l’instrumentation du site, cette stratégie sera adaptée en fonction des
perspectives offertes en ce sens d’ici 2011 (maintenance de certains équipements au lieu de leur
récupération). En 2011, il est prévu de récupérer tous les capteurs de T° C autonomes déployés sur 5 sites du
champ hydrothermal (Nuno, SEAMON Ouest, Tour Eiffel-SEAMON Est, Y3, Statue of Liberty ; voir Figure en
fin de document 2), et le volet d’acquisition de données sur sites sera complet (écologie, chimie des fluides sur
les deux sites SEAMON, et géodésie). Il est également prévu une plongée pour nettoyer le site de tous les
déchets qui auraient pu s’accumuler autour des noeuds SEAMON au cours ou avant l’expérience. Le
déroulement général sera le suivant :
1. Récupération ou maintenance des instruments connectés. La récupération des Nœuds sera effectuée
par Victor en utilisant des mouillages de flottabilité. Victor ira ensuite connecter le mouillage flottabilité
et le Nœud avant de larguer le lest de descente. L’étape de récupération a été estimée à 6 jours.
2. Récupération ou maintenance des instruments autonomes et des mouillages.
3. Acquisition de données sur site (écologie, géodésie, chimie) : Pour les volet écologie (5 jours), et
chimie (échantillonnage des fluides chauds et des fluides diffus ; 3 jours), la stratégie sera identique à
celle de 2010. Pour le volet géodésie, 6 jours sont prévus pour une seconde campagne de mesure du
réseau géodésique (10 repères installé et mesuré une première fois en 2006 ; voir carte en fin de
Document 2). La mesure du réseau, effectuée avec le “pressionaute” de l’IPGP un outil comprenant
plusieurs jauges de pression Paroscientific, suppose des boucles de mesures (voir fiche de
valorisation de la campagne GRAVILUCK).
4. Travaux de surface : Les périodes de reconditionnement de Victor (8 heures entre chaque plongée)
seront mises à profit pour effectuer des profils CTD / Rosette au dessus du volcan de Lucky Strike, afin
de mieux contraindre la structure de la colonne d’eau au cours de la campagne.
5. Une plongée « nettoyage de site » dans le cadre de la gestion de l’aire marine protégée est prévue en
2011. Les lests abandonnés seront localisés sur les mosaiques photo (voir fiche de valorisation de la
campage MoMAR2008-Leg1). La procédure de remontée ou déplacement de ces lests est à étudier.
Nous ne proposons pas de calendrier précis pour la MoMARSAT 2011. Son déroulement sera en grande partie
similaire à celui de la campagne 2010. Les principales modifications seront une durée plus courte des
opérations sur l’infrastructure SEAMON, mais l’ajout de 6 jours de mesure du réseau géodésique. Si la

N.O. pourquoi pas ? Option préférée car il offre 30 places pour l’équipe scientifique (cf Document 5- Equipe
Scientifique) et une importante surface de laboratoire. Une navette (financée par ESONET) sera effectuée
avec le N/O Archipelago pour une rotation de 6 personnes.
L’utilisation de l’Atalante entraînerait une révision du projet (séparation en 2 legs et perte de flexibilité dans
l’organisation).
Submersible : VICTOR 6000.
La stratégie proposée repose sur les capacités de Victor à travailler en mode chantier sur ces zones
perturbées (Sarradin et al. 2002, Michel et al. 2003, Sarrazin et al. 2006, Sarradin et al 2007).

Annexe : Description de certains instruments propres aux équipes demanderesses :
The Ocean Bottom motion meter, Univ. Bremen
The equipment consists of one instrument, the OBM. The OBM has a weight of about 170kg (in water 60kg). It
has a triangular shape with a triangular base plate on three legs. Overall dimensions of the OBM are 1.36 m for
the long edge, 0.68 m for the perpendicular bisector of the base plate and 0.96 m for the short edges, with a
total height of the instrument of 0.78 m. The OBM must be leveled at the sea floor, so that a ROV is necessary
for installation and recovery. The OBM dimensions are such that it can be deployed by the ROVs Quest, KIEL
-5
2
6000, Jason 2 and Victor 6000. The OBM has accelerometers with 10 m/s resolution, to record acceleration
from DC to 10 Hz in three perpendicular directions. It has a tilt sensor with two perpendicular horizontal axes
with 0.1 rad resolution, to record local slow sea floor tilt. An absolute pressure gauge (Paroscientific
DigiQuarz) with Bennest technology is integrated in the system and records vertical seafloor displacements
with respect to the sea surface with millimeter resolution. Additional thermistors record sensor temperature and
sea water temperature, to control environmental conditions for OBM operation. The OBM runs autonomously,
but monitoring in real-time through a network are preferred.
During the cruise the OBM has to be prepared for deployment, i.e. all components and the batteries have to be
checked thoroughly before the OBM will be deployed by an ROV. It will continuously record long-term time
series of acceleration, tilt, pressure and temperature until recovery during the second cruise by an ROV. The
OBM should be installed next to one of the geodetic benchmarks and the pressure data recorder at the summit
of the volcano. We prefer to integrate it in the network depending on the networks capability, but it can also run
autonomously. The time series of acceleration, tilt, pressure and temperature will be analyzed for their spectral
information and correlated for the interpretion of seafloor deformation processes and magmatic and
hydrothermal activity.
CTD/ADCP package
The equipment consists of a CTD, a profiling Doppler current meter, a central data logger and an energy
supply. The instrument package is completely autonomous. It will be programmed for the mission and the data
will be read out after retrieval. An autonomous instrument package consisting of a CTD sensor, an ADCP and a
data logger together with the necessary energy supply will be deployed. A location close to a hydrothermal vent
has to be selected preferably where fluid samples are taken as well. The data set collected will consist of the
following parameters – temperature, pressure, salinity and current speeds. Theses data will be sampled at a
repetition rate of 0.25 Hz continuously with a total time endurance of 3 months. If possible the system should
be deployed at least for these three months. No specific preparatory work on board or on shore is needed. The
system can be deployed by the elevator of IFREMER and then be positioned by the ROV VICTOR.
After retrieving the raw data from the sensor systems some post processing has to be done to achieve time
synchronisation and filter out outliers. To be able to interpret the data adequately it is also necessary to know
precisely about the topography around the measurement location and to have knowledge about tide cycles. A
basic model is currently developed at the University of Bremen but it will be essential to discuss and evaluate
the data with a colleague from Lamont Doherty Laboratories, Andreas Thurnherr, who is an expert in this field.
He already indicated his interest in participating in the data evaluation.
Temperature sensors
The sensors are autonomous and can record T at a rate of <5 min over >1 years. They are available for
measurement of high-T (>400°C) and low-T (<100°C) fluids.
Data wil be processed upon the recovery of the instruments in 2011, to study temporal variability (tidal forcing,
random T variations, seasonal/current-induced changes), spatial correlation of these variations among different
sites, and their correlation with seismicity.
NOC chemical and temperature sensors
NOC though NERC funded programmes has been involved in the development of sensors for the
determination of dissolved reduced species of manganese and iron. Early work demonstrated the use of the
Mn sensor on Autonomous Underwater Vehicles (AUV’S) in shallow coastal systems (Statham et al., 2003,
2005). This technology was developed further and recently the sensors developed at NOC for the
determination of Fe and Mn species, in collaboration with the WHOI deep submergence group, and had
success in the pin-pointing of hydrothermal vent sites using AUV’s (German et al., 2006). The use of a Fiber
Bragg grating allows the multi-point temperature sensing with a high level of accuracy and sensitivity. It is
envisaged that a number of sensing nodes will be deployed around the selected vent sites. We are in the

process of developing and in-situ methane sensor as part of the MOMARnet project, this is showing great
promise and we will have a fully deployable prototype of the system for the cruise in 2010.
We will require time to integrate our sensors onto the system to be deployed during the cruise, this will occur
ideally before the cruise. We envisage that the system for dissolved iron and manganese will have a
functioning life on the order of 2 months. The temperature sensor and the methane sensor will be operable for
the entire length of the deployment. We will require a minimum of 3 people on each cruise. This will allow the
deployment of the systems, and, we will work in association with Valerie Chavagnac to collect fluid samples for
the chemical characterisation of the environment at the time of deployment and recovery.
TEMPO
TEMPO [Sarrazin et al. 2007] is a long-term imaging module equipped with a deep-sea video camera and two
LED lights. An efficient biofouling protection is installed on the camera port hole and on the lights. A CHEMINI
Fe in situ analyzer and 3 temperature probes are coupled to the TEMPO module to monitor environmental
changes in parallel to community dynamics. The whole system is powered by a SEAMON node [Blandin et al.
2005]. TEMPO was tested and deployed during the Momareto cruise and was set to acquire time series (video
images, temperature and Fe concentrations) during 3 months on the bottom. Due to technical difficulties, it has
not been possible to recover TEMPO in 2007, but data is stored in the instrument, and recovery is planned for
the summer of 2008.
A second generation of in situ chemical analyzer (CHEMINI, Vuillemin et al. in press) based on flow analysis
and colorimetric detection was used for the analysis of total sulfide and iron II or total iron (II + III, Sarradin et
al. 2005).
Sampling followed by on board analysis remains often the only analytical way to complement the range of
geochemical species covered by in situ sensor, and to validate data obtained by in situ measurements. Pepito
is a small volume water sampler combining high number of samples (up to 25). It has been tested and used for
many different purposes: ground truthing of the CH4 sensor, in situ filtration, sampling of water samples in the
water surrounding hydrothermal assemblages.
The Aanderaa dissolved oxygen (DO) sensor 3830 is a life-time based optical sensor based on dynamic
fluorescence quenching (Tendberg et al.) .

ANALYSE ET TRAITEMENT DES ECHANTILLONS ET DES DONNEES
L’analyse et le traitement des données concerneront les 5 thèmes définis dans le document 1 :
• Thematic Package 1: Seismicity and hydrothermal activity
• Thematic Package 2: Vertical deformation of the seafloor at the Lucky Strike volcano
• Thematic Package 3: Chemical fluxes at Lucky Strike vents
• Thematic Package 4: Ecology at Lucky Strike vents
• Thematic Package 5: Physical oceanography
Dans les § qui suivent nous ne rentrons pas dans le le détail des traitements prévus : des informations peuvent
être trouvés dans le document 1, les références bibliographiques, et les fiches de valorisation des campagnes
antérieures.
Les données analysées à bord proviendront d’échantillonnage (fluides et biologie), de capteurs manipulés par
le ROV, de capteurs autonomes déployés pour de courtes durées (≤ durée campagne), de capteurs
autonomes déjà en place avant la campagne, et des capteurs connectés à SEAMON pour lesquels l’ensemble
des données n’auront pas été transmises par satellite (ex : sismomètre, caméra vidéo). Vous trouverez un
tableau de tous ces instruments dans le document 1 (§ 4). Un tableau spécifique aux instruments connectés à
SEAMON se trouve dans le document 2.
Le travail à terre concernera d’une part les données en temps semi-réel transmises par l’observatoire, et
d’autre part le traitement plus poussé des données acquises pendant les campagnes.
L'essentiel de l'exploitation des résultats devra être réalisé dans un délai de 12 à 24 mois après la seconde
campagne.
L’aspect original par rapport à des campagnes d’instrumentation plus classiques sera le fort poids donné à
l’intégration de données de type très différent (ex. données sismique et chimie, température des fluides), et
l’ambition des objectifs en termes de gestion et d’archivage des données. La mise au point d’une politique de
dissémination des données et d’une stratégie de traitement de ces données multidisciplinaires est un des
objectifs du projet MoMAR-Demo (cf plan de travail prévisionnel, Section 6 du Document 1).
La liste des participants et leurs principales responsabilités thématiques figurent dans le document 5.

1-4 Vertical deformation of the seafloor at the Lucky Strike volcano
En 2010, récupération des données des capteurs de pression qui auront été réinstallés en 2009 pendant
Bathyluck-2009 (localisation sur carte document 2), récupération des données GPS acquises en cours de
campagne puis dépouillement. En 2011, les données d’un des capteur de pression auront été récupérées en
temps semi réel, ainsi que celles des deux GPS (bouée Borel et station fixe à Faial). On mènera la seconde
campagne de mesures du réseau géodésique (5 ans après la première en 2006) et on intégrera ces données
aux données des deux capteurs de pression permanents.
1-5 Physical oceanography
Acquisition et traitement des données de CTD, d’ADCP de coque et, en 2011, d’un an d’enregistrement des
capteurs de température sur le mouillage de la bouée Borel.
2- Analyses et traitements des données en temps semi-réel transmises par l’observatoire
Les modalités de ce traitement feront l’objet d’un groupe de travail mis en place dès le printemps 2009 par le
projet MoMAR-Demo. En tout état de cause, ce traitement se fera en étroite collaboration entre les 4 thèmes
qui bénéficieront de données transmises par SEAMON et acquises par les capteurs autonomes, afin de
coupler, les données de température, de chimie des fluides, de sismicité, et de déformation verticale du sol. Un
des objectifs du travail préliminaire au cours de l’année 2009-2010 sera de préparer la détection d’évènements
dans une optique de « réponse rapide » et de faire l’interface avec les ingénieurs qui mèneront l’adaptation des
instruments au système SEAMON. Par exemple modifier le rythme d’échantillonnage de certains capteurs,
éventuellement organiser une intervention sur zone avec l’Archipelago (par exemple faire des prélèvements
d’eau pour détecter un panache après une éruption).
Analyse régulière des données transmises par SEAMON, suivi des enregistrements des capteurs
environementaux.
Analyse régulière des données transmises par les capteurs de chimie.
Analyse régulière des données transmises par l’OBS.
Analyse régulière des données transmises par le capteur de pression et par les 2 GPS (bouée Borel et station
fixe à Faial).
3- Analyses et traitements à terre des données acquises pendant les campagnes
Pour l’interprétation, il sera primordial de maintenir une communication étroite entre les groupes des différents
thèmes. En effet, l’essentiel du bénéfice scientifique viendra de la confrontation des données des différents
capteurs.
Plusieurs réunions sont prévues dans le cadre du projet MoMAR-Demo. Une réunion générale sera organisée
en fin 2011 afin de finaliser le traitement des données temporelles acquises par les différentes équipes.

4- Archivage
Les opérations effectuées pendant la campagne seront archivées via le logiciel embarqué Alamer. Les
échantillons et données seront ensuite référencés dans la base de données BIOCEAN et associés à leur
détenteur. Cette base sera consultable par les participants à la campagne. Les rapports de plongées et les
données acquises par le submersible seront accessibles après la mission sous forme de CD-ROM. Les
données vidéoscopiques brutes seront à la disposition des participants de la campagne après engagement de
confidentialité vis-à-vis des médias.
L’archivage, et le contrôle des données issues des campagnes et délivrées par l’observatoire seront pris en
compte par le département IDM Ifremer sur une base existante. Les modalités de cette prise en compte seront
définies en début de projet par les participants, en accord avec les standards ESONET et internationaux. Les
principes de la mise à disposition des données pendant la durée du projet seront approuvés par chaque
participant et répondront également aux spécifications qui seront définies dans le cadre du NoE ESONET. En
fin de projet, ces données seront accessibles via la base de données ESONET.

3 - Collaborations prévues : reportez vous aussi à la Section 7 du Document 1
Les collaboration établies pour MoMARSAT sont celles du projet MoMAR-D et recoupent donc la structure du
NoE ESONET.
Les participants à terre ou en mer du projet, qui viennent de France, d’Allemagne, du Portugal et du Royaume
Uni. Nous avons aussi, via les « Work Packages » d’ESONET, des collaborations prévues avec un plus grand
nombre d’instituts européens et extra-européens. Par exemple, tout ce qui concerne le « Data management »
sera mis au point en lien avec le WP correspondant d’ESONET, et nous avons déjà des interactions avec
plusieurs partenaires non participants à MoMARSAT, pour le développement des communications acoustiques
en particulier.
Une mention spéciale va à Neptune Canada avec qui nous aurons des liens importants, via le MoU qui lie
l’Ifremer et l’Université de Victoria. Nous avons aussi des collaborations prévues avec les partenaires du futur
réseau Marie Curie SENSEnet pour le développement de capteurs biogéochimiques adaptés aux
environnements hydrothermaux sous-marins.
Au sein du projet MoMAR, la demande MoMARSAT aura des liens avec la demande Hydro-MoMAR ou
MARCHE 3 soumise par J. Perrot et J. Goslin pour la maintenance du réseau régional d’hydrophones.
Nous aurons aussi des collaborations avec l’équipe du projet BioBaz (F. Lallier et al.), si celui si est retenu.
Enfin, les aspects écologie du projet MoMARSAT recoupent certains objectifs du projet HERMIONE (suite au
projet HERMES ; appel d’offre FP7 call ENV.2008.2.2.1.2. Deep-Sea ecosystems). Les participants impliqués
viennent d’Ifremer, IMAR et NOC. HERMIONE, coordonné par P. Weaver du NOCS, est en cours de signature.

ASPECTS INTERNATIONAUX ET ENGAGEMENTS CONTRACTUELS
Contacts préliminaires éventuellement pris et interlocuteurs privilégiés des pays riverains
La zone de travail (Lucky Strike), est située dans la ZEE portugaise. L’équipe portugaise l’Universidade do
Azores (IMAR), à Horta fait partie intégrante du projet ESONET et embarque 2 scientifiques. L’équipe de
l’Université de Lisbonne est responsable d’une partie de l’instrumentation sismique et embarque 2personnes.
Enfin, le centre de Volcanologie et d’Evaluation des Risques Géologiques de l’Université des Açores
embarquera une personne sur la campagne 2011.
Personnel étranger invité, engagements contractuels dans le cadre de programmes européens
Ce projet s’inscrit dans le cadre de l’appel d’offres « Demonstrations missions » du Réseau d’excellence
ESONET. Dans ce cadre, ESONET nous permettra de financer du temps personnel et des frais de
fonctionnement.
Ce projet d’observatoire regroupe des participants de l’Université de Brême, et du centre MARUM en
Allemagne, des Universités de Lisbonne et des Açores au Portugal, et du NOC (Southampton) an GrandeBretagne, tous partenaires du NoE ESONET.
Manifestations éventuelles post-campagnes (colloques, conférences, échanges de personnel)
Le projet de démonstration MoMAR-Demo, retenu par ESONET, comprend plusieurs réunions pre et post
campagnes. Par ailleurs, ce projet sera intégré au travail des différents Work Packages d’ESONET. Il sera
donc discuté dans le cadre plus général des réunions ESONET et bénéficiera des possibilités offertes par
ESONET pour l’échange de personels.
Le projet « Grand public » de MoMAR-Demo reprendra les bases du projet mis en place durant MoMARETO
(Sarrazin et al. 2007) et permettra la dissémination de nos résultats vers le grand public à travers des
conférences, site web, publications et surtout expositions dans le réseau d’aquarium européen. Une
retransmission de plongée en direct est également envisagée.
NEPTUNE Canada
Les résultats obtenus dans le cadre de MoMAR-D pourront être comparés à ceux obtenus par l’observatoire
câblé NEPTUNE Canada. Cette comparaison pourra se faire aussi bien du point de vue technologique (câblé
vs non câblé, antifouling, boîtes de jonction, connecteurs utilisés, …) que scientifique. Ainsi, un module
TEMPO doit être connecté au printemps 2009 sur le site hydrothermal Endeavour (Juan de Fuca). Cette
collaboration s’effectue dans le cadre d’un Memorandum of Understanding signé entre Ifremer et l’Université
de Victoria.

Professional Career
After graduating in 1987 with a diploma of Electrical Engineering from the Institut National des Sciences
Appliquées de Lyon (France), Jérôme Blandin worked for two years in the railway industry as a Test Engineer
for the Franco-British train manufacturer GEC-ALSTHOM. He tested and fine-tuned the motor-blocks of the
future Eurostar high-speed train, in Preston (UK).
He then joined an 18 person company (LIM Geotechnologie) specialized in geotechnical instrumentation, as
the technical responsible for the products of soil-injection process control, for four years. His activities
included the technological choices (mainly in electronics) for the products range, their development, tests and
maintenance and also some sensors enhancement.
In December 1994, he joined the Institut Français de Recherche pour l’Exploitation de la Mer (French
Research Institute for Exploitation of the Sea, IFREMER), as an electronics development engineer for
oceanographic instrumentation. He was involved in numerous projects including the ROV Victor 6000 science
module and the design of the electrical / electronic architecture of the deep sea penetrometer Penfeld. He
introduced the use of a field bus (Controller Area Network, CAN) as a modular and reliable backbone inside
multi-sensor deep-sea platforms. He designed the near-real-time communication system of the deep-sea
seismic observatory GEOSTAR. From 2002 to 2004, he directed the EU funded ASSEM project, a research
and technological development project of a long term distributed seabed monitoring solution, including a
novel modular seabed infrastructure, its real time communication means and the data management system
on shore. The project included two years of development as well as technological cruises with a manned
submersible for demonstrating the monitoring system at scale one. He is currently responsible for the design
of several seabed observatories derived from the ASSEM technology, with applications in slopes stability
monitoring, deep sea ecosystems study and shipwrecks pollution monitoring.

Cher Pierre-Marie,
Desolé pour le retard dans notre reponse, je suis a Vanuatu et donc le coordination va plus lentement!
L'équipe de géosciences marines de l'IPGP est impliquée dans les projets NERIES, BBMOMAR et ESONET MoMAR-Demo.
Pour les aspects sismologiques, nous assurerons le lien du projet avec le réseau NERIES et fournirons l'assistance technique
pour la mise en oeuvre d' OBSs du parc INSU pendant les campagnes MoMARSAT si elles sont programmées. Les
personnes impliquées pour ces aspects sismiques seront : Satish Singh, Wayne Crawford, Romuald Daniel et les ingénieurs et
techniciens assurant la mise en oeuvre du parc d'OBSs.
Cordialement,

Résultats majeurs obtenus :
La campagne Momareto s'est déroulée du 7 août au 6 septembre 2006 au large des Açores sur le navire
océanographique Pourquoi Pas?. La campagne Momareto a permis l'embarquement de 55 scientifiques,
ingénieurs et techniciens de plusieurs nationalités et de quatre journalistes. Deux plongées Victor ont été
réalisées avec le nouveau module de mesures en route et 21 plongées ont été faites avec le module de
prélèvement de base. Quatre plongées ont été effectuées sur le site Menez Gwen, 3 plongées sur le site
Rainbow et 16 plongées sur le site Lucky Strike. Cette campagne, pilotée par l'Ifremer (chefs de mission :
PM Sarradin et J Sarrazin, DEEP/LEP) était divisée en deux legs.
Le premier leg (7-17 août), financé en partie par l'Europe (étape de démonstration du projet européen
EXOCET/D), avait comme objectif principal de valider une quinzaine de prototypes dédiés à l'étude des
écosystèmes marins profonds, développés dans du projet EXOCET/D. L'utilisation au cours des deux
premières plongées du module de mesure en route de Victor, équipé du sondeur multifaisceaux et d'un
sonar pêche a permis i) l'obtention d'une carte micro-bathymétrique de très haute résolution du site
hydrothermal Lucky Strike avec un zoom sur l'édifice Tour Eiffel, ii) de valider l'utilité du sondeur pêche
(collaboration C. Scalabrin) pour la cartographie à petite échelle des émissions hydrothermales et de iii)
vérifier l'interférence soupçonnée entre le SMF et le sonar pêche. Deux caméras de stéréovision (IRIS Ifremer/SM- et CAMEREO -AWI-), permettant la reconstruction 3D de petites structures, ont été testées.
L'utilisation du sonar Tritech "Super seeking dual frequency profiler" pour cartographier la distribution de
la faune et des substrats sur les édifices hydrothermaux a pu être validée techniquement au cours du
premier leg. La partie "imagerie vidéo" (Ifremer/SM) du module d'observation biologique TEMPO a été
testée avec succès lors d'un mouillage autonome. L'analyseur chimique miniaturisé CHEMINI (Fer et
Sulfure -Ifremer/TSI), le préleveur d'eau PEPITO (Ifremer/TSI) ainsi qu'un capteur de méthane (AWI) et
un débitmètre (Cardiff University) ont été testé à plusieurs reprises avec succès dans le milieu
hydrothermal. Le déploiement sur plusieurs jours d'une CTD associée à un profileur de courants
(Université de Brême) à proximité de l'édifice hydrothermal Tour Eiffel a permis l'acquisition de données
de courant à petite échelle autour de la structure. Enfin, les trois outils dédiés au prélèvement et à
l'échantillonnage de la faune (enceinte sous pression Periscop -UPMC-, respiromètres sous pression
DESEARES -Station biologique de Roscoff- et colonisateur microbien AISICS -Ifremer/TSI) ont été testés
avec succès. Mis à part la mise en évidence d’ajustements et d'améliorations possibles sur les
instruments testés, ce premier leg a été un grand succès. Il a également montré l'importance de la phase

de test/validation technologique, initiée à Toulon en avril 2006, avant le passage à l’utilisation
scientifique. Le site web de la campagne Momareto a été lancé, avec l'aide d'un webmaster terrestre, au
cours de ce premier leg.
Le deuxième leg (18 août – 5 septembre) avait pour objectifs principaux de i) rechercher les liens entre
la distribution spatio-temporelle des assemblages de moules et les facteurs environnementaux sur le
champ hydrothermal Lucky Strike, ii) d'étudier la réponse et l’adaptation des organismes hydrothermaux
aux caractéristiques et aux variations à court terme des facteurs du milieu et iii) de communiquer les
avancées de cette campagne en temps réel avec le grand public. Une partie de l'instrumentation testée
au 1er leg a été utilisée avec succès pour l'échantillonnage et l'étude de la faune ainsi que pour la
caractérisation du milieu. Les différentes équipes scientifiques impliquées ont pu mener à bien leurs
expériences et les objectifs globaux sont atteints. Le module d'observation biologique à long terme
TEMPO a été déployé avec succès en fin de campagne sur un assemblage de moules. Il permettra le suivi
de la dynamique de cette faune et de son habitat pendant un an. Tempo constitue la première phase
dans l'établissement d'un observatoire sur le champ hydrothermal Lucky Strike dans le cadre du projet
MoMAR. Des sondes de température et des modules de colonisation ont également été déployés pour
compléter le suivi temporel.
Au niveau communication, la campagne affiche un réel succès avec plus de 18 articles dans la presse, 6
émissions radio et au moins trois émissions TV. Le site web a connu la deuxième plus grande affluence
des sites Ifremer avec 10% du trafic. Il a attiré au moins 10 000 internautes distincts (hors Ifremer) et a
permis une réelle synergie avec les gens du bord. Enfin, une grande première avec la "Nuit des abysses",
une plongée en direct, rediffusée au centre Ifremer de Brest devant 250 personnes.

magnétiques de la campagne SudAçores.
Validation des données :
La campagne a permis d’acquérir des données de magnétisme, de gravimétrie, de bathymétrie
et de réflectivité. Toutes ces données ont été validées (élimination des points aberrants) à bord.
Par l’équipe SIMRAD et par l’équipe scientifique (pour mag et gravi). Ces données ont été
transmises au SISMER sous format ngdc, .mul, .nav et .imo.
EXPLOITATION en cours DES DONNEES :
L’exploitation de base de la campagne est terminée depuis 3 ans. Les résultats, et surtout
l’intérèt renouvellé pour la zone d’étude, qui comprend les sites hydrothermaux du projet
MOMAR, justifient la poursuite d’un travail au delà de cette exploitation de base. Deux articles
utilisant des données de la campagne SudAçores sont en préparation , l’un sur le contexte
tectonique et gravimétrique du chantier MOMAR, l’autre sur la structure sismique des zones à
croûte épaissie (plateaux volcaniques), à partir des données de sismique légère.

The Southwest Indian Ridge (SWIR) is among the world’s slowest spreading ridges (1.4 to 1.5 cm/yr).
Ultraslow-spreading ridges are known to expose large expanses of mantle-derived peridotites in the
seafloor, and could offer similarities, in terms of magmatic and tectonic processes, with the early
stages of oceanization at so-called “non-volcanic” rifted margins.
Our study focuses on the most melt-poor (seismic crustal thickness about 3.5 km ; Muller et al., 1999)
portion of the SWIR, near the Rodriguez triple junction. We report on a large set of new off-axis data,
covering about twice the area of Iceland, and extending to maximum crustal ages about 28 myrs. This
is the first extensive off-axis data set for a melt-poor ultra-slow spreading ridge. It is therefore the
first opportunity to study the temporal evolution of spreading processes in this environnement. Due to
very low sedimentation rates, details of basement morphology are apparent even in the oldest parts
of our study area. We have been able to identify 3 types of seafloor, two of which show no evidence
for a volcanic upper crustal layer. The following paragraphs give a brief description of these two types
of a-volcanic seafloor. In our talk, we will adress two principal questions : 1- how do these a-volcanic
terranes form, and 2- are they truly amagmatic regions of the axis ?
One type of a-volcanic seafloor present in our study area has been described previously as
« corrugated surfaces » in many other regions of slow to intermediate spreading oceans. Corrugated
surfaces in our study area are remarkably abundant: we counted 39 such surfaces, about as many as
have been identified to date throughout the World’s oceans. These 39 corrugated surfaces range in
dimensions from 4 to 73 km in the along-axis direction (i.e. along-axis extension of inferred large
offset normal fault at the time of their formation), and from 4 to 30 km in the spreading direction (i.e.
cumulated offset along these faults over their period of activity). A few of these surfaces are
juxtaposed in a pattern suggesting that they formed as part of a long-lasting episode of large offset
axial normal faulting. The most spectacular of such episodes appears to have affected a ridge length
of more than 100 km, and to have lasted 6 myrs.
The other type of a-volcanic seafloor identified in our study area has no previously described
equivalent, although it does correspond to the off-axis expression of the so-called « amagmatic ridge
segments » that have been described at the SWIR and Gakkel ultra-slow ridges (Dick et al., 2003;
Michael et al., 2003; Sauter et al., 2004). It occurs in the form of broad, spreading-perpendicular or
oblique ridges, with a smooth, locally rounded topography. We called this type « smooth a-

volcanic seafloor ». It lacks volcanic features and exposes ultramafics even when on axis. This is very
different from observations made at the Mid-Atlantic Ridge where basalts are always present on axis,
but where peridotites or gabbros are locally exposed on rift valley walls. Smooth a-volcanic seafloor
represents about 40% of our mapped area, and appears to have been emplaced simulataneously on
both flanks of the ridge, in marked contrast with corrugated surfaces.

1 – Contexte scientifique et programmatique de la campagne
The Lucky strike segment hosts a
central volcano with an active hightemperature hydrothermal system at its
summit.
2 – Rappel des objectifs
The goal of the cruise was to determine
the three-dimensional structure of the
entire crust beneath the center of the
Lucky Strike segment, and to put this in
the context of segment-scale tectonism
and magmatism. SISMOMAR was a
seismic reflection and refraction study of
crustal structure beneath the Lucky
Strike segment of the Mid-Atlantic
ridge. The experiment was composed of
a 4x18 km 3D multichannel seismic
reflection experiment over the top of the
Lucky Strike volcano, a 20x20 km 3D
seismic tomography experiment
covering the volcano and surrounding
axial valley and two long seismic
tomography and reflection lines along
and across the rise axis (Figure 1). We
also collected bathymetric, magnetic and
gravimetric data The reflection data was
collected using a 4.5 km long streamer
towed behind the boat and the refraction
data was recorded using 25 ocean
bottom seismometers (OBS) deployed at
42 sites, SISMOMAR is one of the
Figure 1: SISMOMAR experiment. Map colors indicate depth: purple is ~4 km and red ~1
km. The map is about 120 km wide The 3D reflection experiment lines were tightly spaced
within the yellow box, the 3D refraction experiment shots are indicated by the black lines
and the 2D refraction lines are shown by the red lines. Blue circles show OBS deployments.

largest seismic experiments on the Mid-Atlantic Ridge to date: only the "MARBE" experiment is comparable in terms of
coverage and number of OBSs (Canales et al., 2000a; Hooft et al., 2000; Magde et al., 2000; Hosford et al., 2001). The OBS
positions also provided a good configuration to measure local seismicity and we deployee 2 broadband OBSs to measure the
seafloor "compliance" (flexure under ocean waves), which is sensitive to fluid-filled zones within the underlying crust.
3 – Principaux résultats obtenus (avec quelques illustrations)
The major results of the experiment include:
− The detection of an Axial Magma Chamber reflector beneath the Lucky Strike central volcano, with a major
faults penetrating near to its eastern edge [Singh et al., 2006, Nature; Combier, 2007].
− A crustal-scale velocity model that reveals a low velocity zone with a very interesting shape beneath the AMC
reflector [Seher, 2008].
− Constraints on layer 2A thickness and velocities. Notably, the nature of the upper crust changes radically
across the axial valley bounding walls, whereas it is quite constant along the rise axis.
− Detection of several dozen earthquakes during the time that the airguns were not shooting, including 3
earthquakes in 6 days that were very close to the axial magma chamber region.

Le segment Lucky Strike de la dorsale Médio-Atlantique a été choisi comme cible pour l’installation
d’observations à long terme dans le cadre du chantier MoMAR. Il s’agit d’un chantier pluri-disciplinaire ; la
campagne Graviluck a permis d’acquérir des données dans plusieurs domaines allant de la géophysique, la
géologie, l’océanographie physique à la microbiologie.
L’objectif principal de la campagne était géodésique. Lors de la campagne Graviluck, nous avons, pour la première
fois sur une dorsale lente, initié une expérience visant à mesurer les mouvements verticaux liés à l’activité
magmatique et tectonique qui affectent le volcan central de Lucky Strike et le mur Est de la vallée axiale.
Pour cela, nous avons installé deux stations d’enregistrement en continu de la pression en fond de mer et installé/
mesuré un réseau de repères géodésiques au fond. En tout, 12 repères ont été installés et 9 d’entre eux ont été
mesurés. La précision obtenue sur les différences de pression (donc de hauteur) entre deux repères géodésiques est
de l’ordre du centimètre.
Lors des plongées du Nautile, nous avons également acquis des données de magnétisme et de gravimétrie fond de
mer qui devraient nous aider à mieux contraindre la structure de la croûte océanique.
Réseau géodésique : Les traits et nombres colorés indiquent le trajet effectué durant les différentes plongées de mesure du
réseau. Le nombre inscrit en petit dans les sphères orange correspond au nombre de mesures sur le repère.

Parallèlement au programme de recherche principal axé sur la géophysique et mené avec le submersible Nautile, un
programme d’océanographie physique et de géologie ont été menés principalement de nuit, depuis la surface.
Les données d’océanographie acquises montrent que les hauts topographiques connectant les nombreux bassins à l’axe de la
dorsale et dans les canyons sur des flancs de la dorsale sont des lieux permettant des échanges turbulents très energétiques.
Cela montre que la topographie des fonds sous-marins joue un rôle important dans la circulation océanique globale et apporte
une partie de l’énergie nécessaire à la remontée des eaux profondes vers la surface par mélange turbulent
Des données géologiques photographiques de grande qualité ainsi que des échantillons de roche ont été acquises
principalement avec une caméra tractée (Towcam). Ces données ont permis entre autres de définir la zone où l’activité
volcanique est la plus récente.

Le réseau global de sismomètres et magnétomètres sont utilisées pour déterminer la structure intérieure de la terre, pour
détecter des événements physiques de la terre, et pour localiser étudier des séismes de magnitude 4.5+ à travers la terre
entière. La couverture et résolution de ce réseau sont, pourtant, limitées par la distribution inégale des stations. En effet,
presque toutes les stations sont à terre, laissant des grands trous dans les données dans plusieurs endroits océaniques. Des
stations fond de mer ont été tentes, avec des instruments bien installés (enterrés) pour minimiser le bruit et connecté à terre par
un câble sous-marin. Ces installations sont, pourtant, très chères et ont toujours des problèmes techniques assez importants.
Par exemple, la station H2O, la plus célèbre et le mieux installé des stations sous-marines, installé en octobre 1999 sur un câble
sous-marin entre Hawaii et Californie, n'a fonctionné que trois ans et demi avant de se casser. La réparation, coûtant plusieurs
millions de dollars américains, n'a pas encore été financée.
Nous avons proposé de faire des déploiements beaucoup plus légers des capteurs sismologiques et magnétiques larges
bandes. La partie sismologique, qui consiste en trois déploiements consécutifs d'un an d'un sismomètre large bande, pour une
période totale de trois ans, entre été 2007 et été 2010, s'inscrit dans le cadre du projet Européen NERIES. Le lieu choisi est le
volcan de Lucky Strike, sur la dorsale Medio Atlantique juste au sud des îles Acores. Le choix du site permet à ces instruments
de compléter des données acquis a ce site dans le cadre du programme MoMAR, qui coordonne des études multidisciplinaires
(géophysique, biologie, océanographique, chimique, etc) pour étudier la dorsale Medio Atlantique près des Acores, et dont le
volcan Lucky Strike est un site clé.
L'objectif principal de l'expérience est d'acquérir des donnes larges bandes sismologiques pendant 3 ans, de les rendre
disponible a la communauté scientifique Européen, et étudier le niveau du bruit et de signal sur ces stations. D'autres objectifs
ont été de:
− Acquérir des données larges bandes magnétiques pour évaluer leur utilité dans un réseau global.
− Utiliser les données sismologiques et magnétiques pour contraindre la structure du manteau sous le site Lucky Strike
(une zone avec une alimentation magmatique a long terme).
− Étudier l'amplitude et variabilité des ondes infragravimetrique de la surface des océans au-dessus de le site
− Évaluer si la méthode de tomographie par bruit ambiant a basses fréquences pourrait être utilisé dans les océans.
Dans la première année, nous avons déployé une deuxième sismomètre fond de mer entre le site Lucky Strike et une
sismomètre large bande sur l'île de Sao Miguel, Acores. Nous avons aussi déployé des courantomètres à cote des sismomètres:
un courantomètre doppler qui échantillonnait une fois/seconde pendant 4 jours et un courantomètre mécanique qui enregistrait
tous les 30 seconds pendant 8 mois.
Lors des missions BBMOMAR, nous avons aussi déployé 4 sismomètres courts-periods pour une étude de sismicité du volcan
Lucky Strike. Ces déploiements faisaient partie d'une autre expérience du programme MoMAR (MoMARDREAM et
BathyLuck, chef de projet Javier Escartin), mais c'était plus efficace de profiter des ingénieurs OBS déjà à bord pour notre
expérience. Aussi nous avons pu profiter de notre sismomètre large bande servait pour en faire la 5e sismomètre de ce réseau.
Nous avons récupéré les sismomètres en 2008 après un an de déploiement. Tous ont marché et ont enregistré le bruit du fond
locale ainsi que les tremblements de terre locaux et distants. Nous ne sommes pas encore au point de fournir des illustrations
des résultats.

The monitoring of hydrothermal systems over long periods of times is necessary to understand the processes that take place,
their feed backs, and their controls. Hydrothermal systems are responsible for a sizeable portion of the heat loss of the Earth,
and are involved in important material and chemical exchanges between the deep earth and the surface. We focus our research
on the Lucky Strke hydrothermal vent field, one of the biggest systems found to date and located along the slow-spreading midatlantic ridge. Here numerous vents are spread over an area of 1 km x 1 km, and include both high-temperature vents and zones
of diffuse flow.
We have initiated the instrumentation on the site to recover coincidental and complete time series, including pressure (tides),
seismicity, temperature of fluids, and current meters. This effort is combine with hig-resolution mapping of the area and photo
surveys to identify past and future changes in the distribution of hydrothermal outflows. This instrumental and monitoring effor
is complemented with numerical modeling. All research is coordinated within the MoMAR program.
The main goal is to obtain coincidental data from pressure gauges, seismometers, température sensors, and current meters.
This is complemented by high-resolution geophysical mapping (near-bottom multibeam bathymetry), imagery (electronic still
imagery and video), and sampling for geological, geochemical, and geomicrobiological studies of the Lucky Strike site.
Monitoring was initiated in 2007 with the installation of seismometer, and continued in 2008 with the installation of both
seismometers and pressure gauges. Technical problems prevented the deployment of temperaure sensors at the time. The full
implementation of the project is thus planned for 2009, with recovery of instrumentation and data in 2010.
Instrumentation : We will recover the instruments installed in 2008 in the summer of 2009. Coincidental time series of
seismicity, pressure, and température (partial deployment) will only be initiated in the Fall of 2009.
Mapping : We have created a georeferenced photomosaic of the hydrothermal system from OTUS imagery acquired with
VICTOR. This mosaic extends over an area of ~700x700 m and covers the main active vent areas. Image processing and
georeferencing has been carried out with techniques developed in collaborations with the University of Girona (see Escartin et
al., 2008). Multibeam bathymetry acquired with VICTOR is being processed at the present time, and results available for the
2009 Bathyluck’09 Cruise. Below we present a Small portion of this mosaic, covering an area of 60 m vertically and 45 m
horizontally, where the hydrothermal slab (fractured) and several zones of hydrothermal venting are visible, and correspond to
areas covered with white bacterial mats.
This cruise also included a film crew for a TV documentary.

1- Context
Hydrothermal circulation at mid-ocean ridges is a fundamental process that impacts the transfer of energy and
matter from the interior of the Earth to the crust, hydrosphere and biosphere. The unique faunal communities that
develop near these vents are sustained by chemosynthetic microorganisms that use the chemicals in the hot fluids
as a source of energy. Environmental instability resulting from active mid-ocean ridge processes can create changes
in the flux, composition and temperature of emitted hydrothermal fluids and thus influence the structure of
hydrothermal communities.
multidisciplinary observing system at Lucky Strike during one year. Lucky Strike is a large hydrothermal field
located in the center of one of the most volcanically active segment of the MAR. Monitoring this field offers a high
probability of capturing evidence for volcanic events, observing interactions between faulting, magmatism and
hydrothermal circulations and, evaluating their impacts on the ecosystem.
Two Sea Monitoring Nodes (SEAMON, Blandin, J., Rolin, J.F Sea Technology December 2005, Volume 46, No.
12.) will be acoustically linked to a surface buoy that will ensure satellite communication to a land base station.
The first node will be dedicated to large scale geophysical studies and the second, to edifice scale studies such as
ecology and chemical fluxes. The infrastructure should be deployed in 2010 during the MoMARSAT cruise (see
the Cruise proposal, D1).
The objective of this deliverable is to describe the observatory infrastructure, the interface specifications and to
update the list of sensors to be connected to the SEAMON nodes. The foreseen location of the 2 nodes and the
implementation plan are also presented.
2- Description of the operational system
The MoMAR-D experimental design combines autonomous instruments which will store data over the duration of
the mission (1 year), and instruments that will be connected to shore via the SEAMON system.
2-1 The SEAMON / BOREL technology
The SEAMON system includes a set of long-term, non-cabled sub-sea observatory components, initially developed
by Ifremer during the EU ASSEM project (2002-2004). These components have since been upgraded and made
more reliable. SEAMON is the generic name of the seabed stations serving a local set of sensors, whereas BOREL
(Bouée relais) is the surface data transmission relay. The SEAMON stations are rated for 4000 mwd operations.
Each node can provide 8 kWh, allowing for the sensors operation and for a daily data transmission of ca. 40 – 400
kbytes.
The main components of SEAMON are the following:
COSTOF (Communication and Storage Front-end). This electronic unit serves a set of local sensors by providing
them with data storage, communication channels and optionally energy. COSTOF communicates with the ROV via
CLSI (see below), and the BOREL buoy via acoustic modems. The COSTOF robustness and modularity rely on the
use of a low power field bus (CAN) linking a set of simple identical boards, each board devoted to one sensor. The
measurement sequencing is left to each sensor. This way, a COSTOF failure does not prevent data acquisition at
the sensor level. Conversely, data duplication at the COSTOF level is a safety factor in case of sensor damage.
SEAMON can duplicate this data storage for volume < than 2Gbytes per year.
CLSI (Contact-Less Serial Interface) is a small device made of two halves, allowing serial communication between
two units, without electrical connection. If one half is connected to a ROV, and the other half to the COSTOF,
communication can be established between the ROV and any connected sensor. It is very useful just after the ROV
has completed a sensor mechanical installation, to check or fine tune its functioning before the ROV leaves the
area.

MoMAR-D
The BOREL buoy (Fig.1) is the data transmission relay between the SEAMON
stations and the Iridium satellite constellation. It is moored within acoustic range
of the SEAMON stations and is composed of two identical independent data
transmission channels. Channel 2 can be activated from shore in case of a failure
of channel 1. Each data transmission channel is powered independently and
comprises an acoustic modem, control electronics and an Iridium modem. The
communication is bi-directional and BOREL supports three data transmission
modes: periodic (typical rate 6 hours), triggered by events detected on the seabed,
and triggered from shore. BOREL has now been used for two years in the
Mediterranean Sea, where it was moored at 2000 m depth. The Mediterranean
mooring will be modified for MoMAR-D to take into account the sea conditions
prevailing in the mid-Atlantic. Its position and the local sea/wind state will be
monitored throughout the experiment. The robustness of this mooring is clearly
one of the technical challenges of the MoMAR-D experiment.
Fig.1: The BOREL buoy
2-2 Acoustic data transmission
For five years now, successive SEAMON/BOREL systems have been using the same type of acoustic modems.
Their reliability has now reached a satisfying level, but their energy requirement per transmitted bit (a key
parameter for non-cabled observatories) can probably be significantly lowered. Ifremer is currently working on this
issue. This work started in 2007 with a selection of five modems available on the world market. Among the
selection criteria, the lowest energy necessary to transmit 1 bit at a given distance was sought. In 2008, three of
these five modems were tested at sea, between a sub-sea station at a depth of 2200 m, and the R/V L’Europe. This
test demonstrated that the latest modems require at least 15 times less energy to transmit one bit in those conditions,
than the ones used on SEAMON until now. Longer term tests of the two best modems are planned in 2009,
between the 2200 m-deep subsea station and a relay buoy. The MoMARSAT experiment will directly benefit from
these improvements.
Only a subset of data will be periodically transmitted to shore via the BOREL buoy. The subsampling step will be
designed specifically for each sensor. Simple subsampling operations can be perfomed by SEAMON such as
temporal subsampling, simple statistics, thresholding.
2-3 Configuration of the nodes
Two SEAMON nodes will be deployed in the Lucky Strike vent field (see location in §5). A Table of the connected
sensors, the volume of data transmitted and the energy required for transmission at each node is provides in § 4. A
sketch of the observatory configuration is provided Fig. 2.
• SEAMON-East will be primarily devoted to thematic experiments 3 (Chemical fluxes), 4 (Ecology) and 5
(Physical oceanography). It will connect a video camera, chemical sensors and the CTD/ADCP package.
This node will be moored at the base of the active hydrothermal edifice Tour Eiffel, near the location of the
autonomous TEMPO station deployed during the MoMARETO cruise.
• SEAMON-West will be primarily devoted to thematic experiments 1 (Seismicity and hydrothermal
activity) and 2 (Seafloor deformation). It will connect the pressure probe and one OBS. This second node
will be moored in the western part of the lava lake, near the present location of the pressure probe installed
since 2006.
2-4 Underwater connection devices
To ease the deployment, the OBS will be be connected to SEAMON underwater using a low cost connection
device (CdC,) specially developed and validated during the ASSEM project (Fig. 3).

2-5 Data storage
Each connected sensor will independently store data over the 12 months duration of the project. When possible
(volume < than 2Gbytes per year ), the data storage will be duplicated by SEAMON. The Ecology package
(TEMPO) and the pressure gauge already have tested operational SEAMON connections. Development will be
carried out for the connected OBS (IPGP), the NOCS chemical flow analyzer and the CTD/ADCP mooring. Other
sensors will be deployed as autonomous instruments, storing data that will be recovered at the end of the 1 year
experiment.

Biofouling is a major issue in the vent ecosystem. Biofilms form on every available surfaces and trap the mineral
particles emitted by the hot fluids. The method used successfully (Exomar, 2005 and MoMARETO, 2006) for
preventing bio-fouling on the lens of the TEMPO video camera and on an Aanderaa oxygen optode relies on
localized microchloration. This method does not modify the image, and the concentrations of chemicals released
are negligible.
3- Interface specification
The “Instrument integration specifications” is detailed in annex 1.
4- The sensors
The project relies on the mooring of various sensors to acquire time series related to the seismic activity of the
system, the floor deformation, the chemical fluxes, the dynamics of the fauna and the physical oceanography of the
area. Part of the sensors will be connected to the SEAMON nodes and will transmit a subset of data to the Borel
buoy and the DMAS on shore. The complete data set will be stored in the sensors and in SEAMON when possible
(see §2.5). The other sensors will be used in an autonomous mode.
The complete set of data will be downloaded at the end of the experiment when the sensors are recovered.
All the sensors will be synchronized at the beginning of the experiment. The drift will be measured after the
recovery of each sensor against the GPS clock.

5- Location of the nodes
The location of the nodes and buoy is presented in Fig. 4. The Borel buoy will be moored at acoustic range of the 2
nodes, on the volcano heights. The geophysical node (Seamon West) will be moored in the lava lake on a flat
surface. The photomosaic of the area obtained by Escartin et al. (2008, Gcubed, V9, N12) will be helpful to find the
convenient place. Finally, the ecological node (Seamon East) will be located at the base of the Tour Eiffel active
edifice, to continue the study started by the TEMPO module in 2006.

6- Planning
The Fig.5 describes the project planning. The instruments adaptation phase correspond to the modification of the
instruments prior to their connection to SEAMON. The SEAMON adaptation phase will allow the development of
specific drivers for each instrument. During the instruments integration to SEAMON, the sensors will be integrated
(mechanically and electrically) to SEAMON. The system test will be performed on shore using the complete
system: from the sensor to the DMAS.

Anti-corrosion precautions
We request that each instrument connected to a Seamon station be self protected against corrosion for a
duration of at least 18 months. In particular:
-A set of protective anodes shall be mounted on the instrument body and electrically linked to all metallic
parts of the instrument in contact with seawater.
-The metallic parts of the instrument in contact with seawater shall be isolated from any electrical potential
shared with the rest of the station (power and data lines) and from the instrument electronics.
-The Ifremer team in charge of the mechanical mounting will ensure that all external metallic parts of the
instrument are isolated from the station structure.
