Deep Life Community -‐ The Deep Carbon Observatory – 2014-‐2015 ALFRED P. SLOAN FOUNDATION www.sloan.org | proposal guidelines PROPOSAL COVER SHEET Project Information Principal Investigator Mitchell L. Sogin, Ph.D. 7 MBL Street, Woods Hole MA 02543 mitchellsogin@gmail.com 5085661468 Grantee Organization: Woods Hole Amount Requested: st Requested Start Date: January 1 , 2014 st Requested End Date: December 31 , 2015 Deep Life Community-‐ The Deep Carbon Observatory—2014-‐2015 Project Goal The Deep Life Community (DLC) seeks to map the abundance and diversity of subsurface marine and continental microorganisms in time and space as a function of their phylogenomic and biogeochemical properties, and to explore their roles and interactions with the deep carbon cycle. Objectives This proposal will strengthen our nascent research and coordination organization dedicated to achieving DLC’s decadal goals. It will extend molecular studies to a greater number of samples from high-‐value marine and continental sites in order to describe diversity, distribution and functional adaptations of deep life. It will explore life’s interplay with geological processes in the deep subsurface including studies of microbial activities and distributions in hydrogen-‐rich habitats, which favor abiogenic synthesis of methane and higher hydrocarbons. We will: a) Explore the limits of deep life using improved life detection capabilities, b) Develop and apply tracer approaches to track the flow of carbon into biomolecules and cells, and c) Measure the interrelationship between composition of carbonaceous materials and deep life. To achieve these objectives, the DLC must seek additional resources and engage the best deep-‐life researchers from around the globe. Proposed Activities The Census of Deep Life (CoDL) will support marker gene analyses for 1600 new samples or metagenomic analyses of as up to 100 samples. The DLC will cohost a workshop with the Deep Energy Community (DEC) on abiotic H2 generation and will collaborate with DEC on methane isotopologues in biologically produced methane spanning temperatures from 20°C to 120°C. The DLC will use stable-‐ and radioisotope probing to trace the utilization and assimilation of carbon compounds in subsurface environments. The DLC will support laboratory activities and expenses associated with the preparation of compelling research proposals, workshops with the International Ocean Discovery Program (IODP) and the International Continental Scientific Drilling Program (ICDP) for developing biological drilling initiatives, and co-‐funded meetings with the NASA Astrobiology Institute (NAI) or the Center for Dark Energy Biosphere Investigations (C-‐DEBI) to develop new collaborations. This proposal will support DCL-‐wide meetings in 2014 and 2015, and will support DCL-‐wide participation at the 2015 Deep Carbon Observatory (DCO) “all hands” meeting. Expected Products Expected products of these proposed activities include publications about deep subsurface microbes and microbial mediated processes on the cycling of carbon; online molecular data describing deep life diversity and processes; new research proposals to leverage Sloan funding; and DLC-‐dedicated field missions with participation from other DCO communities. Expected Outcomes This proposed activities will generate new insights about diversity, evolution, and processes that govern deep life and its role in the cycling of deep carbon. Finally, it will expand the constituency of the DLC and will enlighten the public about microbes deep underground.

Studies of terrestrial and marine sediments reveal subsurface microbial ecosystems that harbor ≥1029 organisms with total carbon content possibly equaling all surface life [1, 2]. These deep and dark biological reservoirs may extend to six km or more beneath the seafloor and continental surface. Instead of tapping into solar power, members of deep subsurface microbial communities harvest energy from geofuels or buried, refractory detrital matter, exploiting small disequilibria between chemical redox states in order to drive the synthesis of macromolecules and biological reproduction. These processes lead to large-scale transformations of inorganic and organic compounds with an attendant impact on the deep carbon cycle. Within the deep biosphere, some organisms survive and grow near the interface of the abiotic and biotic realms, where high pressures, elevated temperatures and energy limitations require the ability to tolerate and adapt to extreme conditions. How deep subsurface microbes differ from surface and near surface organisms remains unknown. Adaptations of deep life to high pressures and temperatures, limited energy resources, diffusion limited transport of nutrients and other environmental factors may require different rule sets that govern primary production, competition, succession, dispersal, and their mode of evolution. First order questions about organisms that inhabit this largely unexplored environment include: Who is there? How is deep life distributed and what is its biomass? How do they survive? How quickly do they reproduce and what provides a source of energy? What factors govern their dispersal patterns and how do they rapidly adapt to a changing environment? What is their impact on the deep carbon cycle? The Deep Life Community (DLC), which explores the evolutionary and functional diversity of Earth’s deep biosphere and its interactions with the carbon cycle, embraces three primary Decadal Goals: 1) Determine the processes that define the diversity and distribution of deep life 4 Deep Life Community - The Deep Carbon Observatory – 2014-2015 as it relates to the carbon cycle; 2) Determine the environmental limits of deep life; and 3) Determine the interactions between deep life and carbon cycling. Each of these goals addresses aspects of Quantities, Movements, Origins, and Forms (QMOF): Quantities (concentrations of cells that constitute deep life and its carbon content), Movements (Dispersal and Distribution of microbial life and its carbon substrates), Origins (Abiotic vs Biotic sources of substrates fueling deep life) and Forms (Different genotypes and phenotypes, as well as compositional and redox states of carbon) of deep life. Our research strategy will leverage DLC’s investment in conducting a global census over time and space for all three domains of life and viruses in both the marine and continental subsurface. Through omics we seek to explore mechanisms that shape microbial evolution and dispersal in the deep biosphere and to identify the ecological rules that shape community structures. Studies of the environmental limits of life employ a combination of laboratory and field experiments to determine physical and chemical extremes that are compatible with life. These measurements will inform modeling studies and potentially will provide clues about differences between the biotic/abiotic interface that may have played a role in the origins of life. Finally, Deep Life will explore patterns and mechanisms of bioticallymediated carbon transformations in the subsurface and the interaction of these processes with the surface world. As described below, the DLC has progressed towards exploring the diversity and distribution of life in marine and continental deep subsurface environments. Laboratory experiments have investigated pressure limits on microbial survival, and omic studies have provided insights about the role of microbes in the deep carbon cycle. Despite these achievements, the DLC faces daunting challenges that require funding beyond what the Sloan Foundation can provide. This proposal will continue building the DLC, provide resources for research coordination activities, and support activities that can lead to newly funded initiatives. 5 Deep Life Community - The Deep Carbon Observatory – 2014-2015 2 - DEEP LIFE COMMUNITY ORGANIZATION – PARTICIPANT QUALIFICATIONS. The 2010 DCO Deep Life Workshop on Catalina Island California convened by Mitchell Sogin, Katrina Edwards and Steve D’Hondt set DLC’s initial agenda. Microbiologists, biogeochemists, and geochemists outlined research goals in the white paper Deep Subsurface Microbiology and the Deep Carbon Observatory [3]. Major recommendations of the report included surveying the deep biosphere through a Census of Deep Life (CoDL), investigating deep life’s evolutionary history, exploring the global distribution of microbes in the deep biosphere, inventorying their metabolic character, identifying how they have adapted to high pressures and high temperatures, and determining the influence on microbes on the deep carbon cycle in both continental and marine subsurface habitats. Fredrick Colwell and Mitchell Sogin developed a CoDL proposal that the Alfred P. Sloan Foundation funded in late 2010 and the DCO recruited Isabelle Daniel and Mitchell Sogin to serve as Co-Chairs of the DLC. In June 2011, the steering committee for Deep Life met in Bremen to review DLC research proposals solicited by the DCO secretariat. The DLC identified the most important common themes in the proposals and charged Matt Schrenk and Isabelle Daniel with organizing the Deep Life I: Microbial Carbon Transformations in Rock-Hosted Deep Subsurface Habitats Project (RHC). This multi-investigator project (with 11 laboratories spanning 7 countries) seeks to describe and quantify the metabolic activities of microorganisms in the rock-hosted subsurface biosphere. The project includes observational studies of key understudied deep subsurface environments coupled with experimental investigations aimed at elucidating the physiological underpinnings of microbial adaptations to these environments. This research focused on the hypothesis that rock-hosted deep biosphere communities use abiotically-sourced carbon compounds and that unique high-pressure, hydrogen-enriched environments shape the deep biosphere communities. In early 2013, Kai-Uwe Hinrichs joined Mitchell Sogin as Co-Chair of the DLC. Isabelle Daniel remains on the DLC 6 Deep Life Community - The Deep Carbon Observatory – 2014-2015 steering committee but has also assumed the chair of the Deep Energy Community. The section CURRICULUM VITAE provides c.v’s of the advocates for this proposal including DLC Steering Committee members who have led major efforts in Deep Life research projects. 3 - DLC RESEARCH ACCOMPLISHMENTS – 2012-2013. The CoDL and RHC have synergies that have contributed to remarkable progress over 18 months. Seventeen research groups received important data from the initial phase of CoDL’s marker gene (rRNA) survey. A second phase enabled by reduced sequencing costs added sites to the census and offered opportunities for shotgun metagenome surveys. Eleven laboratories participated in the RHC project. APPENDIX A.4 provides a list of publications, manuscripts in review, and manuscripts in preparation. APPENDIX A.3 cites leveraging activities that have supported DLC science. 3.1 - PROGRESS BY THE CENSUS OF DEEP LIFE (CODL) (F. Colwell, M. Sogin) • Desulforudis audaxviator represents a “keystone species” in subsurface samples from South African gold mines, seafloor crustal materials, and Great Basin wells and springs. • A subglacial Icelandic microbiome lacks Archaea and consists of only five microaerophilic and anaerobic chemolithoautotrophs [4]. This unique subsurface microbial community does not receive input of energy from the surface (i.e., sunlight or photosynthetically-derived organic matter) and could serve as an analogue for life in the subsurface of other planets. • Firmicutes dominate deep methane hydrate zones in the sediments of the Indian Ocean including zones above, within and below strata that contained hydrates [5]. The absence of Archaea in these samples - and by inference, methanogens – agrees with prior reports that concentrations of methane producing microbes must be very low in hydrate-bearing sediments • Pilot scale geological sequestration of CO2 [6] will utilize deep basalt aquifers that host diverse bacterial and archaeal communities. Microbes at the depth of planned CO2 injection 7 Deep Life Community - The Deep Carbon Observatory – 2014-2015 are related to taxa that use hydrogen and single-carbon compounds. The metabolic activity of these communities could impact long-term stability of carbon sequestered underground. • High-resolution mineral colonization experiments in the sub-seafloor igneous crust reveal that mineralogy and mineral chemistry dictate the types and diversity of attached microbes (Smith et al. in review). Geological formations rich in olivine (e.g., slow-spreading ridges) serve as hotspots for biological activity in oceanic crust, where biogeochemical processes on crustal minerals rather than transported products of photosynthesis fuel microbial growth. 3.2 - PROGRESS BY DEEP LIFE I: MICROBIAL CARBON TRANSFORMATIONS IN ROCK-HOSTED DEEP SUBSURFACE HABITATS PROJECT (RHC)– (Matt Schrenk, Isabelle Daniel, T Kieft) • Molecular diversity studies, supported by measurements of H2, CH4 - rich and pH, of timeseries samples from active serpentinization environments of uplifted ultramafic oceanic crust at the Coast Range Ophiolite Microbial Observatory (CROMO) in northern California identified Betaproteobacteria and Clostridales as key taxa. Collaborations with the CoDL and DOE community sequencing program have identified pathways such as assimilation of small organic acids and carbon monoxide that putatively control the exchange of carbon and energy between the deep Earth and the surface environment. • Coupled molecular and 13 C tracer studies of microbial communities in diffuse hydrothermal fluids collected from the world’s deepest known hydrothermal vents at the Mid Cayman Rise (MCR) in the Caribbean Sea documented microbial and functional diversity for abundant taxa related to Methanococcales, Archaeoglobales, and Epsilonproteobacteria. Diffuse fluid samples from vents located on basaltic and ultramafic substrates between 2000 and 5000 m water depth hosted taxa typical of more well-known high temperature systems at the deeper site (Piccard) and taxa that may be involved in methane production at the shallower ultramafic rock site (Von Damm). These data will provide insight into links between the microbial 8 Deep Life Community - The Deep Carbon Observatory – 2014-2015 communities and their geochemical environment. Gene sequencing and stable isotope tracer experiments indicated that methanogenesis from formate occurs at the ultramafic hosted sites, and is absent from the deeper, higher temperature basalt hosted sites such as Piccard. • Fluorescently activated cell-sorting and taxonomic-screening of 10 samples from deep fractures in Precambrian Shield environments of South Africa, Finland, and Canada identified close relatives of Candidatus Desulforudis audaxviator, which dominated communities in earlier studies of South African gold mines. To understand the ecology, population genetics, and biogeography of these microbes in the deep subsurface, the JGI Community Sequencing Program, will generate draft genome sequences for 200 single-cell genomic preparations. • The RHC project has isolated and characterized 5-10 new strains of novel, thermophilic, piezophilic organisms from the MCR and the Precambrian Shield environments. One of the strains isolated from the MCR grows well at 120 MPa (corresponding to 12 km water depth!). Physiologic and genomic characterization of these isolates will provide insight into the adaptations of microorganisms to deep subsurface, high-pressure environments. • Biophysical and biochemical studies of Shewanella oneidensis adapted in the lab to 2.5 GPa (comparable to depths of ~75 km), identified two pressure domains. Beyond 500 MPa, the physiology of the P-adapted S. oneidensis appears to be very different. Quasi Elastic Neutron Scattering experiments to 200 MPa revealed that the mobility of water across cell membranes decreases slightly with pressure but is many orders of magnitude less than the decrease in metabolic activity measured over the same pressure range using X-ray spectroscopy. 4 - THE PROPOSED PROJECT: DEEP LIFE RESEARCH AND COORDINATION NETWORK. The Deep Life Community steering committee has developed a research agenda / networking plan that leverages advances from the CoDL and the RHC project, and outlines opportunities to engage initiatives beyond the current umbrella of the Deep Carbon Observatory. This plan 9 Deep Life Community - The Deep Carbon Observatory – 2014-2015 incorporates new elements that address key objectives in each of the three primary Decadal Goals (APPENDIX A.2). Beyond scheduled meetings and modest continued funding for the Census of Deep Life, the DLC must seek sources of funding from other foundations and agencies. Over the next two years, the DLC will strategically deploy limited resources to support community building (networking), workshops, logistical expenses of writing new proposals e.g. travel to other laboratories, small-scale laboratory and field experiments (including the collection of samples of opportunity and collaborative initiatives with other DCO communities), and the purchase of affordable equipment or accessories that would further the research agenda of the DLC. The collective goal is to advance deep life science through discovery based research and enablement through new successful research proposals. The appendix A.6.2 describes the mechanisms and guidelines for submitting ideas to the DLC steering committee and the criteria that we will use to render decisions about resource deployment. Unlike more traditional pilot project opportunities, decisions about support will largely hinge upon the potential impact on success of new funding proposals to other agencies or foundations. 4.1 - CENSUS OF DEEP LIFE – PHASE II-III – (A. Boetius, R. Colwell, S. D’Hondt, M. Sogin). The Census of Deep Life (CoDL), seeks to identify the diversity and distribution of microbial life in continental and marine deep subsurface environments. This project directly addresses deep life’s Decadal Goal I to develop a global 3-D census of diversity in continental and marine deep subsurface environments and to explore mechanisms that govern microbial evolution and dispersal in the deep biosphere. It contributes to Decadal Goal II by informing us about the limits of life and metabolic properties necessary to adapt to deep subsurface environments. CoDL activities integrate closely with the RHC project by providing a taxonomic framework for describing and comparing deep subsurface communities. With the introduction of shotgun metagenomics, the CoDL will address key functional questions about deep life. 10 Deep Life Community - The Deep Carbon Observatory – 2014-2015 During Phase I of the CoDL, 17 laboratories submitted samples for analysis. Phase II of the project accepted a second round of samples from 12 research groups (in progress) and Phase III (supported through this proposal) will support a larger number of samples but at significantly reduced costs. Samples for analysis will continue to include drill cores of rock and sediment, water pumped from newly drilled wells, seeps in mines, crustal fluids, in situ colonized media from CORKS as well as samples of opportunity from other DCO communities. CoDL’s general experimental strategy relies upon massively parallel DNA sequencing for 1) “marker gene” studies that inform us about the relative abundance and kinds of microbes in a sample, and 2) shotgun metagenomics investigations that capture information about the metabolic potential of microbial communities. Both extract information from microbial DNA from deep subsurface samples. Our original strategy employed pyrosequencing technology but the CoDL transitioned to the Illumina MiSeq platform, which can reduce sequencing costs/sample by ~100 fold. The Phase 3 CoDL project will accept many more samples with an investment of less than $100,000. The CoDL portal on the web site VAMPS (http://vamps.mbl.edu) will provide access to the data and a wide range of analytical capabilities including the ability to process data through the QIIME paradigm [7]. Cross project synthesis activities through formation of a collaborating working group will provide descriptions of distribution and dispersal patterns for microbes in the deep subsurface. For metagenomic analyses, the CoDL will take advantage of an Illumina HiSeq platform, which provides ~6 fold coverage for any 2-4 Mbp genome that accounts for >0.2% of the microbial genomes in a sample. This information has the potential to provide detailed genotypic descriptions of the metabolic and functional capabilities of typical communities from deep subsurface environments. By coupling estimates of community diversity from marker gene analyses with shotgun metagenomics, we will be able to titrate the amount of shot-gun 11 Deep Life Community - The Deep Carbon Observatory – 2014-2015 metagenomic sequencing required to infer the functional properties of microbial populations in deep subsurface communities. With appropriate sample preparation to isolate viral particles, this technology will support shotgun metagenomic analysis of viral populations. 4.2 - DEEP LIFE II: ROCK-HOSTED COMMUNITIES. Projects listed below are being generously supported during the current funding cycle. In the 2014-2015 funding period, we anticipate that the activities by the RHC will be increasingly supported by leveraged funds. The DLC will deploy additional resources as requested to complete tasks necessary for data synthesis and for securing funding from outside sources. 4.2.1 - METAGENOMICS AND DEEP CARBON CYCLING (M. Schrenk, T. Kieft). In just a few short years, the CoDL and RHC studies have dramatically improved our understanding of microbial diversity in deep subsurface environments, spanning both marine and terrestrial realms and advanced our understanding of the interplay between abiotic, geological processes operating at depth and deep life, capitalizing upon coincident advances made in the technology of gene sequencing. These studies have fed into complementary “–omics” approaches, including metagenomics, transcriptomics, and single cell genomes which have enabled a broad view of microbial metabolic potential, activity, and population genetics in subsurface environments. Focused efforts have made headway in the collection and preparation of samples from low biomass environments and assembly from short sequence reads. Coupled with leveraged resources, such as the DOE Joint Genome Institute Community Sequencing Program, these efforts have begun to pay dividends in terms of the accumulation of massive amounts of genomic data. Automated sequence annotation, using programs such as the MG-RAST server have permitted the initial high-throughput analysis of these datasets. However, the accurate annotation of these genes requires verification with reference organisms harboring sequences coding for bonafide functions. Further, a sequences-specific phylogenomic approach allows for analysis of 12 Deep Life Community - The Deep Carbon Observatory – 2014-2015 the evolutionary relatedness of these microbial communities. Alignments have been constructed for several genes expected to be critical for carbon cycling in the deep subsurface (e.g. methanogenesis, carbon fixation, formate assimilation) and will be expanded to include other genes related to carbon processing. These alignments will facilitate the rapid analysis of new metagenomics datasets, expected to be a part of the next phase of the CoDL, and for phylogenetic analyses relating deep life across habitats. Genomic information gathered by the RHC will address central goals in the DLC’s agenda but will require additional efforts in annotation and phylogenetic reconstruction. We anticipate several requests for modest support to resolve these questions. 4.2.2 - ABIOTIC H2, ABIOTIC ORGANIC C, AND ORIGINS OF LIFE. (M. Schrenk, T. Kieft, I. Daniel, D. Bartlett). In certain subsurface settings, deep life is independent of photosynthetically generated energy and instead relies on abiotic H2 derived from either rock-water reactions [8] or radiolysis of water [9], or on simple organic C compounds generated abiotically via FischerTropsch-type reactions [10]. Subsurface habitats harboring these chemosynthetic ecosystems fueled by abiogenic H2 have even been suggested as sites for the origins and early evolution of life [11]. The RHC project has facilitated a range of research projects that investigate the physiology and ecology of hydrogen-utilizing subsurface microorganisms, including those influenced by serpentinization (CROMO and Cayman Ridge) and radiolysis (Witwatersrand Basin, South Africa), and the DEC focuses on the abiogenic production of organic compounds. We will strengthen this framework through investigations that link the process of carbon assimilation in abiotic H2-generating environments with analysis of microbial genomes. The work will build upon the RHC’s and DLC’s expertise in stable isotope probing, isotope analysis of various carbon pools from bulk to cellular and molecular levels, and single-cell genomics and will link studies of carbon reservoirs and fluxes conducted by DE, e.g., at the CROMO site in 13 Deep Life Community - The Deep Carbon Observatory – 2014-2015 California, USA, and the Bay of Prony site in New Caledonia. We seek to identify microbes that utilize abiogenically produced H2 and carbon substrates, and to obtain genetic and biochemical information to reveal evolutionary relationships and metabolic pathways. Beyond explaining how microorganisms in the deep subsurface assimilate carbon, these analyses will provide a framework for inferring relationships between the biochemistry of extant systems and origins of life scenarios in the deep subsurface. 4.2.3 - INTEGRATION OF DATA SETS BETWEEN STUDIES (M. Schrenk, M. Sogin, I. Daniel). The RHC sub-projects will continue to integrate with each other and the CoML. The Census of Deep Life will anchor taxonomic descriptions and comparison of deep subsurface ecosystems. Measurements using similar protocols for stable isotope tracer measurements across each of the field sites, will allow comparison of the rates and types of operative metabolism. The sharing of samples and microbial cultures among research teams will facilitate comparative analyses into a larger synthesis that describes carbon cycling by the rock-hosted microbial biosphere. We seek to compare microbiomes across all different subsurface realms, including continental vs marine, rock hosted vs sedimentary, organic rich vs organic poor, hot vs cold. 4.3 - LINKING DEEP LIFE TO DEEP ENERGY COMMUNITY INVESTIGATIONS. During the past few years, an important synergy has developed between projects pursued in the Rock-Hosted Communities (RHC) project and the Deep Energy Community (DEC) of the DCO. The RHC project has made headway in understanding microbial activities and distributions in hydrogenrich subsurface habitats, which favor the abiogenic synthesis of methane and higher hydrocarbons. In parallel, the DEC has initiated a range of investigations, including fieldwork in both marine and terrestrial settings and laboratory experiments, to identify sources and signatures of methane and other hydrocarbons. The process of serpentinization, the aqueous alteration of ultramafic rocks characteristics of Earth’s upper mantle has become a centerpiece in both types 14 Deep Life Community - The Deep Carbon Observatory – 2014-2015 of investigations. Likewise, the joint interest in carbon transformations and microbial communities in subsurface zones associated with the biotic-abiotic interface unifies both DCO communities and will provide a breeding ground for future collaboration. Several areas of focus have emerged. Studies in both Deep Life and Deep Energy have strived to inventory microbial processes and their impact upon carbon biogeochemistry in subseafloor rocks from locations such as the Mid-Cayman Rise and the Mid Atlantic Ridge. Studies initiated through the CoDL and the DEC are examining microbes in shallow sea hydrothermal chimneys in New Caledonia venting volatile-rich, high pH fluids. Scientists in both communities took part in the Oman Drilling Workshop, co-sponsored by ICDP and DCO, in Palisades, NY in September 2012. Laboratory experiments in both communities are serving to constrain the geochemical processes and signatures associated with abiogenic hydrocarbon production, and how they are intertwined with the deep biosphere. These same processes may ultimately be operative at the depth limits to the biosphere in the uppermost mantle and lower crust, and in forearc basins associated with subduction zones. Serpentinization-associated processes may play important roles in influencing the exchange of carbon and energy between the deep Earth and the biosphere. Furthermore, these mineral catalytic systems are believed to have played a role in the origins and early evolution of life. Serpentinizing environments inhabited by microorganisms may contain biochemical relicts of ancient prebiotic processes. We propose to build upon these efforts with a series of strategic investments, e.g., in the form of collaborations between DLC and DEC, including: • Co-hosting a workshop with the DEC on the topic of abiotic H2 generation and the associated potential to support life. This workshop will highlight both geochemical and biochemical aspects of the process and its impact on the carbon cycle through time and be hosted at a site near a serpentinizing ophiolite (e.g. Portugal, Northern Italy). (I. Daniel, M. Schrenk) 15 Deep Life Community - The Deep Carbon Observatory – 2014-2015 • Collaboration on methane isotopologues (K.-U. Hinrichs; with B. Sherwood Lollar, DE) – DLC will collaborate with DEC on the examination of clumped isotopes in biologically produced methane covering a temperature range from 20°C to 120°C. A good fraction of this temperature range overlaps with temperatures at which methane may be formed abiotically in subsurface systems. Examination of the associated signals will be crucial for the development of methane’s clumped isotopes as an indicator of its formation pathway. • Cataloguing microbial abundance and diversity (M. Schrenk, R. Colwell, T. Kieft, D. Bartlett, I. Daniel) in sites that are currently being investigated by the DEC, but which lack a microbiological component (e.g. gas fluxes studies of serpentinizing ophiolites, carbonated seafloor rocks, active drilling projects, etc.). Cultivation efforts will allow physiological studies at high pressures in the laboratory. 4.4 - NEW FRONTIERS IN DEEP LIFE (K.-U. Hinrichs). The DLC has identified a number of key tasks of direct relevance to our ability to reach our decadal goals. For example, we must improve life detection capabilities, develop new tracer approaches to track the flow of carbon into biomolecules and cells, and advance our ability to measure the interrelationship between composition of carbonaceous materials and deep life. The DLC Steering community will encourage submission of ideas for modest short-term support that will address these and other relevant / meritorious efforts with high potential to attract new funding from other agencies and foundations. (see section A. 6.2.). • Investments in stable- and radioisotope probing experiments, for example in the context of the RHC project, to trace the utilization and assimilation of carbon compounds commonly found in subsurface environments (e.g. CO2, formate, acetate, methane) linked with single-cellgenomic approaches to query their genetic potential and diversity. 16 Deep Life Community - The Deep Carbon Observatory – 2014-2015 • Generation of biochemical profiles from novel microbial isolates obtained from subsurface ecosystems, including lipid biomarkers, sporulation-related molecules, and Raman spectroscopic signatures that can inform and expand upon geochemical studies [12]. • Improving life detection capabilities in order to differentiate between live and dead cells, to develop and implement molecular markers diagnostic of active cells, and to reduce detection limits of cellular and molecular life markers. Future initiatives targeting the biotic-abiotic interface (see below) will inherently depend on these improvements. • Advancing our quantitative and qualitative understanding of the relationship between deep life and cycling of carbon. For example, the impact of deep life on the fluxes and redox state of carbon entering subduction zones [13] as well as the influence of deep subseafloor life on oceanic carbon budgets are poorly constrained. Likewise, the biochemical mechanisms associated with the microbial utilization of kerogen, Earth’s largest organic carbon pool, are essentially unknown. We hypothesize that structural properties of kerogen strongly influence the release kinetics of metabolizable smaller carbon compounds and are thus intimately linked to the activity of deep heterotrophic life. The DLC will support field and experimental studies targeting the detection, biochemical mechanisms and kinetics of microbially-induced structural modification of organic matter in the subsurface using modern mass spectrometry, spectroscopy, NMR, rate assays, metabolomics and genomics approaches. As described above under 4 - THE PROPOSED PROJECT: DEEP LIFE RESEARCH AND COORDINATION NETWORK, initiating and developing these frontiers may require seed funding to capture preliminary data for new applications to foundations and agencies. Appendix A.6.2 STEERING COMMITTEE ACTIVITIES. Expanding Deep Life Support; for selection mechanism and criteria. 4.5 – STRATEGIC PARTNERSHIPS THAT BUILD THE DEEP LIFE COMMUNITY. The Integrated Ocean Drilling Program (IODP) and the International Continental Scientific Drilling Program 17 Deep Life Community - The Deep Carbon Observatory – 2014-2015 (ICDP) support expensive scientific field projects that drill into the subsurface. IODP and ICDP have sponsored drilling for biologically useful samples that led to important findings that appeared in high profile research papers. The path to funding drilling from these organizations is arduous and highly competitive. We envision multiple avenues for DCO to work with IODP and ICDP to foster further deep carbon-relevant studies that involve deep life. These range from small studies with short lead times to long-term development of a transformational combined marine/continental drilling projects that address DL Decadal Goals. Deep Life proposes to leverage IODP and ICDP funding in support of biological studies in three ways: • DLC support (up to $10K inclusive of travel, supplies e.g. drilling fluid tracers and lab expenses) for PIs and/or their students to join near term deep drilling projects (<1 year in the future) that have a high potential to generate biologically useful samples, but that currently have no participating biologists on board. This modest level of support will supplement existing dedicated funding opportunities on the national level for post-expedition research available in several countries (e.g., small science-directed grants from U.S. Science Support Program with the Consortium of Ocean Leadership) and could also allow support of DLC investigators to participate in non-IODP/non-ICDP deep drilling programs that access the subsurface (e.g., US Department of Energy related projects). • Workshops to develop new proposals. Deep Life will fund workshops either directly at ~$30k or with ~$15k to match IODP or ICDP funds, e.g. for so-called Magellan Workshops to develop deep biosphere-inspired drilling projects that often result in full drilling proposals to IODP or ICDP, or to initiate / strengthen the microbiological component of existing proposals previously designed from a geological perspective. These will be multidisciplinary but will have deep life and deep carbon as central themes. Smaller workshops will support participation of ~five DLC members to develop projects of opportunity in the framework of 18 Deep Life Community - The Deep Carbon Observatory – 2014-2015 IODP via so-called ancillary project letters (APL) that seek to take advantage of scheduled deep drilling expeditions with no obvious link to DL but which could be extended by a DLdedicated hole. We will also support joint workshops with the NASA Astrobiology Institute (NAI) and the Center for Dark Energy Biosphere Investigations (C-DEBI) to develop collaborative projects that span marine and continental subsurface systems. • We will also explore the concept of merging IODP and ICDP support for drilling an onshoreoffshore transect to address scientific questions that straddle continental marine boundaries. IODP and ICDP achieved this while coring the New Jersey Margin, [14] and scientific questions involving processing of carbon in the deep biosphere across marine/continental gradients could warrant such an ambitious drilling effort. As just one example, high-latitude sites where permafrost and methane hydrates sensitive to temperature change link the deep biosphere to the planet’s surface along a continental/marine transect [15]. The DLC will start this long-term (ca. 6-year) team-building, fund-raising effort by co-organizing a workshop and soliciting funding and participation from other DCO Communities, as well as IODP, ICDP, NAI, and C-DEBI to develop collaborative projects that span marine and continental subsurface systems. Products from the workshops include accelerated involvement of DLC researchers in ongoing expedition planning, alignment of expedition research questions with the DL Decadal goals, identification of essential scientific disciplines and key teams for addressing those questions, and a workable plan for funding a PI or small group of PIs (e.g., from NSF, the Moore Foundation, the Keck Foundation) to develop full proposals to IODP and ICDP and to advocate with these organizations and funding agencies for support. DLC will assign liaisons with IODP and ICDP who will maintain an active list of current projects from these two programs that could serve the DLC and vice versa. 19 Deep Life Community - The Deep Carbon Observatory – 2014-2015 • With participation of representatives from the DE and RF communities, the DLC will prepare and lead a deep ocean drilling proposal (submission of a pre-proposal is schedule for Oct 1, 2013) to utilize DV Chikyu for probing the presumed biotic/abiotic temperature interface in deeply buried, geothermally heated subseafloor sediments in the Shikoku Basin off Japan. At two sites that have been previously drilled during ODP Leg 190 (Sites 1173 and 1174), the critical temperature zone between 80 and 140°C could be probed over a several hundred meters at a total subseafloor depth of less than 1 km. Previous initial studies of deep life at these sites by John Parkes and colleagues [16, 17] have demonstrated overlapping zones of deep life and abiotic, thermal processes that supply substrates and thereby potentially stimulate microbial communities. Based on existing cellular count data [18] however, the subsurface strata in which sterilization is likely to occur has not been possible due to high detection limits on the order of around 105 cells/mL. This location provides an excellent opportunity to determine the temperature limit in a sedimentary subseafloor microbial ecosystem and characterize the zones where life goes extinct. A dedicated expedition with a science team dedicated to DL and DE objectives would benefit from the advances in deep life investigative strategies made during the last decade. Fundamental research goals could be accomplished at this location; these include “constraining the T-limit of life in the sedimenthosted subseafloor; studying the relationship of abiotic chemical reactions at high T and biology; the physical and chemical characterization of horizons where life becomes extinct. Constraining the deepest limits of life is one of the most fundamental questions for the DLC community (Decadal Goal 2). The discoveries resulting from this would be of great interest to geoscientists, life scientists and astrobiologists and the public. • Partnerships with private industry. Both the mining and oil and gas industries offer opportunities for exploring deep microbial life by providing access to sample cores, drilling 20 Deep Life Community - The Deep Carbon Observatory – 2014-2015 fluids, or resources for analysis. For example, S. D’Hondt and M. Sogin are working with ExxonMobil Upstream Research to develop an exploratory project to study microbial community structure in a wide range of subsurface and surface environments. The project will utilize sequencing technologies described for the CoDL to analyze samples from globally distributed reference sites collected by different IODP expeditions and oceanographic expeditions. ExxonMobil Upstream Research will provide $250,000 for a pilot project and if successful will significantly expand the project over the next decade. 4.6. - SUMMER SCHOOL DEEP MARINE BIOSPHERE. DL co-chair Kai-Uwe Hinrichs will organize the 2014 ECORD (European Consortium of Ocean Research Drilling” summer school “Subseafloor Biosphere: recent advances and future challenges” at MARUM, University of Bremen. This 8th annual ECORD summer school will provide a unique program of training for 30 international graduate students and postdocs working in the broader DLC. The program consists of one week of lectures by international experts, many of them directly associated with DLC, and a second week of “virtual ship” experience with hands-on laboratory work that includes methods such a microbial cell counts and sediment core descriptions, supervised by scientist and staff from the Bremen IODP core repository (leveraging: $32,000 in funds by ECORD and MARUM to support travel of international lecturers and the virtual ship experience. 4.7 - MBL INFORMATICS COURSE. M.L. Sogin will direct the course “Strategies and Techniques for Analyzing Microbial Population Structures”. This 10-day immersion course will focus on design and analysis of marker gene and shotgun metagenomic projects for advanced graduate students, postdoctoral fellows and established investigators who seek to leverage the power of massively-parallel DNA sequencing technologies for investigations of microbial communities from a range of environments that span the deep subsurface to the human microbiome. 21 Deep Life Community - The Deep Carbon Observatory – 2014-2015 4.8 - DATA SCIENCE. Mitch Sogin serves as the liaison to the Data Science Advisory Committee led by Peter Fox. The DLC stands ready to contribute meta data and information about samples and projects to the Data Science Group. The CoDL and associated genomic investigations require data capabilities that extend beyond the scope of the Data Science Group. Instead, the WEB site VAMPS (http://vamps.mbl.edu) provides an analytical platform for analysis and visualization of marker gene surveys. It offers a portal that links all metadata including detailed project descriptions to the large molecular datasets. It also provides functional ties to the QIIME analysis pipeline and soon will link into the Earth Microbiome Project through VAMPS and QIIME. Shotgun metagenomic data will be submitted by users for analysis on the MGRAST platform [19]. The DLC will follow a data release policy that requires release of data within 9 months of generation of immediate release of data that appears in published manuscripts. 4.9 – ENGAGEMENT. Steve D’Hondt serves as the Liaison to the Engagement team led by Sara Hickox, both at URI-GSO. He will convey information about scientific developments/successes, new collaborations, workshops, and DLC meetings to the Engagement team. Steve D’Hondt has led IODP expeditions and is co-PI on the C-DEBI Science and Technology Center. 5 - OUTPUT OF RESEARCH PROJECT • Expanded opportunities for students and postdocs to study deep life • Two intensive training courses (informatics and deep marine biosphere) • Expanding the international DL community to include the best deep life scientists • Development of novel methods for identifying biosignatures in the deep subsurface • Quantification of live vs. dead, active vs. inactive, and vegetative cells vs. spores • Document and characterize abiotically derived carbon assimilation in serpentinization environments in collaboration with the Deep Energy Directorate including methane isotopologue studies to discriminate biotic from abiotic methane in the deep subsurface • Document how deep subsurface life adapts and evolves through evolutionary genomics 22 Deep Life Community - The Deep Carbon Observatory – 2014-2015 • Inventory of organic C forms in select deep marine and continental sites • Identification of microbes metabolizing those organic C compounds • Extend the CoDL to include other sites and those under investigation by DCO communities. • Addition of a microbiological component to non-biologically oriented subsurface projects • New biology-driven IODP and ICDP deep scientific drilling projects • Will perform a cross project synthesis of life’s distribution in the deep subsurface • Publication of key scientific findings in open access journals 6 - BUDGET JUSTIFICATION AND LEVERAGING. In contrast to the DLC’s research activities enabled by generous funding from the Alfred P. Sloan Foundation, this proposal describes a strategy for securing resources necessary to realize Deep Life’s primary Decadal Goals within the next eight to ten years. It builds upon research success over the past two years and the growing interest in Deep Life. We describe a science plan that will require significantly greater resources – some of which are already in hand. The Deep Life has community has identified ~$26,000,000 to fund science that addresses some of our primary decadal goals (See Appendix A.3). The budget in this proposal will sustain CoDL activities, build the Deep Life community through a modest size annual meeting, fund Steering committee activities, support workshops and data synthesis groups, and participation in the 2015 DCO meeting. We have also reserved significant resources for to support travel, workshops, and small-scale science projects for Post Doctoral Students, Graduate Students and Investigators who seek to advance the decadal goals of the DLC. The BUDGET provides full details and Appendix A.6.2 STEERING COMMITTEE ACTIVITIES describes the rationale for allocating resources, the application mechanism, review criteria and the review process for the funding of DLC activities. 7 - PRIOR SLOAN SUPPORT: See - 3 – DLC RESEARCH ACCOMPLISHMENTS – 2012-2013. page 7 23 Deep Life Community - The Deep Carbon Observatory – 2014-2015 8 - BUDGET 9 - CURRICULUM VITAE Kai-Uwe Hinrichs Ph.D. – Co-PI.

A.2 - DECADAL GOALS 37 Deep Life Community - The Deep Carbon Observatory – 2014-2015 Overall Summary of Deep Life Deep Life exerts a vital influence on Earth's subsurface carbon fluxes and reservoirs. It exploits Earth's deep energy at the intersection between abiotic and biotic realms. The Deep Life Community will map the abundance and diversity of subsurface marine and continental microorganisms in time and space as a function of their phylogenomic and biogeochemical properties, and their interactions with deep carbon. By integrating in situ and in vitro assessments of biomolecules, cells, communities, process rates and subsurface habitats using advanced measurement, imaging, and cultivation technologies, we will describe the environmental limits to deep life, its survival, metabolism and reproduction. The resulting data will inform experiments and models that seek to measure Deep Life’s impact on the carbon cycle, to constrain biologically-mediated structural alteration of deep reservoirs of carbon and other elements, and to define the deep biosphere’s relation to the surface world. Decadal Goals: DEEP LIFE: The Deep Life Community will explore the evolutionary and functional diversity of Earth’s deep biosphere and its interaction with the carbon cycle. I. Determine the processes that define the diversity and distribution of deep life as it relates to the carbon cycle. Examples of research focus include: • • • Conduct a global 3-D census over time of biological diversity (Bacteria, Archaea, Eukarya, viruses) in continental and marine deep subsurface environments. Investigate whether specific mechanisms govern microbial evolution and dispersal in the deep biosphere. Determine what ecological rules explain deep microbial community structure, e.g. spatial and temporal scales of community turnover, the role of the rare biosphere, and the effects of limited dispersal. II. Determine the environmental limits of deep life. For example we will: • • • Probe and test life’s response to physical and chemical extremes using observation, experimentation in the laboratory and in the field, and modeling. Explore what genomes can tell us about the limits and possible origins of life. Establish a bio-energetic framework for understanding the limits and adaptation of life in the deep subsurface. III. Determine the interactions between deep life and carbon cycling on Earth. For example we will: • • • Determine the principal pathways of carbon transformations in the subsurface and quantify the rates of these reactions. Characterize transitions between abiotic and biotic realms. Quantify how these processes interact with the surface world.

The Co-Chairs Kai-Uwe Hinrichs and Mitchell L. Sogin have formed a partnership to co-lead the Deep Life Scientific Steering Committee (SSC). As part of our efforts to expand internationally, we have invited Fumio Inagaki of JAMSTEC to serve on the DLC SSC. Drs. Hinrichs and Sogin will schedule Scientific Steering Committee meetings (a minimum of one dedicated in-person DLC SSC meeting each year, quarterly video conferences, and inperson meetings linked to the 2014 and 2015 Deep Life Community Meeting and the 2015 DCO “all-hands” meetings). Either Hinrichs or Sogin or (when possible) both will represent the DLC at in person and teleconferencing DCO Executive Committee meetings. The entire Steering Committee will participate in the planning of DLC annual meetings, workshops, and organization of special sessions at national and international meetings and conferences. 47 Deep Life Community - The Deep Carbon Observatory – 2014-2015 Liaison activities and resource management. Sogin will serve as the liaison to the DCO Data Science Team and D’Hondt will serve as liaison to the DCO Engagement Team (See 4.7 DATA SCIENCE, p. 21, and 4.8 ENGAGEMENT, p. 22. The Co-Chairs will assume fiduciary responsibility for managing DLC resources from the Sloan Foundation in consultation with SSC members who will provide leadership in developing proposals that seek new resources for scientific exploration that addresses the DLC Decadal Goals. Expanding Deep Life Support. The DLC has articulated an ambitious science agenda that will require resources that extend well beyond funding provided by the Sloan Foundation. The collection of samples and their interrogation through cultivation, chemical characterization and genomic analysis requires major investments that cannot be satisfied through the funding of salaries for a few post doctoral and graduate students over the next two years. Instead the DLC must extract information from its existing complex datasets and develop techniques and strategies for taking deep life research to the next level. At the DLC May, 2013 meeting in Portland ORE, with extensive community input the DL steering committee settled upon a strategy that will enable generation of new information from which to leverage new research proposals. As described under 4 - THE PROPOSED PROJECT: DEEP LIFE RESEARCH AND COORDINATION NETWORK, the DLC has set aside resources that will enable activities – both scientific investigations and synthesis activities, that will serve a key role in developing new proposals. The budget has set aside >45% of our direct costs to support DLC activities that lay the groundwork for new proposals. Unlike grants from a funding agency or foundation, these resources will have a short spending period of <= 6 months during which they should address the following criteria: a) Requests for support must address unresolved questions related to deep life and its decadal goals; b) Requests must identify the potential for attracting additional funding 48 Deep Life Community - The Deep Carbon Observatory – 2014-2015 resources and the description must outline a plan for seeking new research support; c) the amount of support can range from $1000 to as large as ~$25,000 and can be submitted at any time between January 1, 2014 and July 1, 2015; d) The supported activity must conclude within a six-month time-frame. Other criteria that will contribute to an application’s success include: e) the potential for leveraging other funding; f) fostering collaborative science; g) supporting synthesis of knowledge across the different themes; h) support for projects too risky for funding agencies; j) funding projects of opportunity that require immediate resources; i) projects that will enhance international programs and collaborations. By way of example, two days before the final draft for this this proposal was completed, Tom Kieft and Mike Pullin of New Mexico Tech were approved for a Rapid Access (30-day) project at the Environmental Molecular Sciences Laboratory (EMSL) at DOE’s Pacific Northwest National Lab titled Characterization of dissolved organic carbon in deep crustal fracture water using solid state nuclear magnetic resonance analysis. The project will use solid state NMR (~200 hours instrument time) to structurally examine organic matter extracted from deep (0.7-3.5 km) fracture water in South Africa. The deep water samples were collected with partial support from the DCO DL RHC project; the collaboration with EMSL is a direct result of the May 2013 DCO DL meeting in Portland. Kieft will have the opportunity to submit an application for DL support that could lead to securing major funding (NSF, DOE, etc.) for expansion to other analytical approaches (GC-MS, GC-Fourier transform-ion cyclotron resonance MS, etc.) and other sites (continental and marine). This provides an example of how DLC resources can both leverage recent awards from agencies and foundations as well as provide resources to support the submission of new applications for expanded research capabilities. 49 Deep Life Community - The Deep Carbon Observatory – 2014-2015 The DLC will accept 3-4 page applications for such support without specific deadlines throughout 2013-2015. The Deep Life section on the DCO website (http://www.deepcarbon.net/content/deep-life) will disseminate this information and we will use e-mail lists to notify members of the DLC of this opportunity. In addition we will share announcements of these opportunities with allied research initiatives such as C-DEBI. The Steering Committee (exclusive of members who participate in authorship of the proposed activity under evaluation or who have an inherent conflict of interest) will review the merits of proposals and render recommendations for funding to the Co-Chairs during in person meetings or quarterly video-conferences. Decisions by the Steering committee for supporting an activity will consider its impact on one or more DCO DL Decadal Goals; building the DL – DCO community, the potential for leveraging other funding; their influence on fostering collaborative science and synthesis of knowledge across the different themes; proposed activities too risky for funding agencies; novel opportunities with immediate funding requirements; and activities that will enhance international programs and collaborations. 50
