ln the pa t year, Iike ail federal government
agenci and departmenrs, the Canadian Polar
Commi ion has had to confront the realities
of reduced budget in an effort ra rackl the
federal defi it.
The Commi ion accepts the principle
that deficit reduction i in the nationallnter­
e t. However, we maintain that a trang com­
mitment and pre ence in polar science is also
in the national inter t. It i vital ra develop­
ing and maintaining the northern environ­
ment, the health and well-being of northern
Canadian , and a viable northern economy.
Rather than impeding the develop­
ment of polar science, the current c1imate of
fiscal review and re-evaluati n afford the
o portunity ta re-examine our northem prior­
iti . If pr per.ly con idered, deficit reduction
may even erve ta complement and trength­
en our national efforts in polar cience.
ince irs establi hment in 1991, the
Commi i n ha advocated rhe need for much
greater co-ordination among the various fed­
eral government departmenrs and agencies

Bur while rhe promotion of science is
an importam part of the CPC' work, it i not
a sole priority. The Commi ion erves a a

ln acc pting the award from Mini ter of
Indian Affair and orthem Development,
the Hon. Ron Irwin, at a special ceremony
June 19 in Ottawa, Dr. Roots stressed the need
ta look ahead rather that recall

"We should not dwell on wharever we

Dr. Roots u ed the occasion to link the
future priorities for northem science ra key
developments in the region over the pa t half
century-political and economic maturiry,
combineJ with a new en e of elf- uffi ien y,
and the increa ing integration of the North

The Commi ion believe an inrerde­
partmenral p lar re earch council would he a
key 'tep toward the co-ordination of Canada's
efforts in polar cience. For the fir t time in

overall federal effort in the Norrh, we would
be able ra recognize and avoid duplication and
redundanr programs, we would re-establish
our priorities, and we would addre many of
the new cientifie and rechnological chal­
len es facing northern regions.
Thi" pring, the Commi ion released a
proposed federal polic'l' for polar science,
TOll'ard aPolicy for Canadian Polar Science and
Technology. It i the Commi ion firm belief
that thi policy, upled \Vith the recommen­

Information series.
Ozone
Oxygen makes up about Zl per cent of the air
we breathe.
Oxygen oeeur in mree forms in me
atmosphere: single oxygen atams (0), tela­
tively un table and found particularly at high
altitude; relatively stable oxygen moleeule
(OZ); and ozone (03)' more reactive than
oxygen and found in the upper atmosphere.
Comprising le than .0001 per cent of
the atmo'phere, ozone i a colourle ga with
a trang, pungent odour. It is formed in the
presence of high energy source such as light­
ning or ultraviolet radiation, and at ground
level.
The average amount of oz ne found
over the poles is abOlit twice as mueh as thar
found over me l'quator. The total zon found
over a particular location will also vary
aecording ta the time of day, season, and air
currents. ln Canada, the atmospherie ozone
can hall' a natural change of 25 per cent
between winter and summer.
The Atmosphere
The particles and gases above the surface of
the earth form the auno phere. The armo ­
phere is necC'Sary for alllife fonus and facili­
tares energy nows and matter eycling that
re ult in earm' climare.
The tropo phere is that part of me
atmo phere cio e t ta the surface of the earth.
It is characterized by a declining temperawre
wicll increa ed altitude. The trapo phete,
warmed by rhe heat radiated from the earth,
exrends [0 abour 17 km above the surface.
This moi t, turbulent air mas' i rhicke t
above the equator.
The strarosphere arises above rhe tro­
po phere and extend ta about 50 km above
the earrh. Here temperarures tend ta increa e
with altitude and the air is dry and statically
table. Almo t ail of the earth' atmo phere is
found in the fir t 50 km above the surface.
Only about 1 per cent extend· beyond the
trata phere.
About 80 per cent of the orone in the
atmo phere is found in the stratosphere at
about the Z5-km altitude level. When sun­
light reaches the stratosphere, it causes sorne
of the oxygen rnoleeule to break apart ioto
5
oxygen acom·. The intense form of unlight
that create· ozone is called ultraviolet radia­
tion. The single oxygen amms bind with other
oxygen molecules mform zone.
Chlorofluorocarbons
(CFCs)
Chloronuorocarbon , or CF ,are u ed in a
wide range of manufa([uring applications,
including refrigeranrs, air-conditi ning,
aero 01 , c1eanina fluid , and blowing agent
for foam. Fir t dcveloped in 1928 il' a replace­
ment for ammonia in refrigeracor', CFCs are
highly stable, non-taxic compounds that tend
not to rcact with other "ubstance or break
down easily under normal environmental
conditions. However, expo ure to ultraviolet
radiation plies the chemical bonds to free
highly reactive chi rin . Afree chlorine amm
can then com ine with one of the oxygen
awrns in zone; the chlorine atom 1V0uld be
fre again hould an individual oxygen atom
be pr nt W form an oxygen molecule.
lndustrial activities are r ponsible for a
ignificanr increase in chi rine in the atmas­
phere. The natural backg und level is estimat­
ed ar 0.6 par per billion by volume (ppbv). By
1991 thi had increased almast ix times, to
3.5 ppbv; ince then, it has continued CO
increase at arate of about 1.0 ppbv each decade.
Although CFC cau e about 80 per
cent 0 the current ozone depletion and are
increasing in the atmo phere at a rate of 5 per
cent co 6 per cent annually, other ub rances
alsc lead mozone depletion. These include:
• hal ns u ed in fire fighting {increa ing at a
rate of Il to 15 per cent annually in the
atmo phere and cau in o 5 per cem deple­
tion)i
• carbon tetrachl ride, u ed a a olvent and
as an ingrcdient for many organic chemi­
cal (increa ing at a rate of 1.5 per cent
annually in the atmo phere but cau ing
les' than 8 per cent depletion);
• hydrochlorofluorocarbon (HCFCs),
developed a a replacement for CFCs
(increa ing at a rate of 7 to 10 per cent
annually but cau ing le than 0.5 per cem

• methyl chlorofom1, used to cIean metal

phenomena appeared in October, the outh­
em pring, but ozone level retumed almo t ta
normal by the end of the ummer. The ozone
depletion had not been predicted by previous­
Iy developed model. Later, atellite imagery
and other data were u d to ubstantiate the
finding.
[n Augu t and eptember of 1987, a
high-altitude sampling of gase in the ozone
h le provided conclusive evidence that deple­
tion of ozone over Amarctica re ulted from
hi hly reactive chlorine originating rom
indu trial activity.
The Polar Vortex
A polar vortex is caused by swirling wind
high in the straco phere during rhe long and
coId winrers over Amarctica. The e wind
form a barrier to the movement of air acr
the vortex boundary. Ama of coId air builds
up in"ide the lar vortex where ozone 1
concemrated.
The manner in IVhich the chemical
reaction leading ra depletion of ozone pro­
ceeds i as follows: Cloud are formed from
warer and nitric acid inside the vortex in the
trato phere (Polar trata pheric Cloud or
P Cs). The more stable and colder the vor­
tex, the grearer the occurrence of PSC' which
lack up most of the nitrogen in the 10IVer
straw phere. Thi nitrogen is often in the
fonn of nitrate which hold the harmful chlo­
rine and bromine. Throu h a complex set of
chemical reactions, chlorine and bromine
molecules are relea ed From the ice in the
P Cs by unlight in the spring. The chlorine
and bromine react with ozone, "rarting achain
reaction that resul in m ive depletion of
the ozone in the early spring. Once the polar
vortex reak' clown and the PSCS melt, air
from around the vortex area begins ta mix
again, and ozone levels rise.
In 19 5, following adecade of tudy, ciemi es
reported the pre ence of an oz ne "hole", or
dra tic ozone reduction of about 30 ta 40 per
cent, over part of Antarctica. Thi revelation
stimulated further re earch and debate. The

A second AA E was undertaken in
1991-92 ro further inve tigare ozone 10 over
the Arctic and mid-latitudes in the northern
hemisphere. The data indicated a loss of
berween 15 per cent and 25 per cent of ail
ozone orne 18 km above the earth. The area
of mo t evere ozone depletion was cen r d on
eandinavia. AA E Il al provided sorne
valuable information on other proce es that
may lead ta ozone depleti n. The eruption of
Mount Pinatubo in the Philippines in June
1991 injected ronnes of aerosols, induding
ulphates, into the atm phere. These fine
partide provide a urface for the chemical
rea tions that re ult in the relea e of ozone­

Record-lowozone level were recorded
in early 1993 at moniroring tations acr
Canada, induding arctie ites at Alere,
Eureka, Resolute, Churchill, and Goose Bay.
Ozone levels for the early part of the years,
prior ro the break-up of the arctic polar vor­
tex, were 14 per cent lower than measure­
m nt made before 1980. A peak 10 of about
30 percent was found at 16 km abovc the
ground in the lower tratosphere. Thi' i com­
parable to what ha oeeurred over the
Antarctic and indudes data from moniroring
ite both in ide and out ide the aretic vortex.
Early evidence from Canadian ozone moniror­
ing tation for 1994 shows that ozone levels
and UV-B levels have rerurned ro do e ro nor­
mal. This indicates that recent trend may
have been enhanced by atmospherie debri
from the erupti n of Mount Pinatubo or that
other unknown atmo pheric and tran port

luJyin u the Effem of O:(\ne Depletion
What's New...
Research conducted by the British Antarctic SUf\'CY (BAS) l\leteorologid and Ozone
\ionitoring Unit indicates that the antarctic ozone hole is still dccpening. Springtimc \'alucs
recorded at the BAS's Halley Research Station ha\'e fallen to Icss than 40 per cent of those
seen in the 1960s. The research suggests, as weil, that the dccline is no longer restricted to
springtime but extends into Sl}mmer, increasing the le\'el of harmful ultra\'iolet radiation
reaching the surface of Antarctica and surrounding ocean~.
The BAS, which has monitored ozone le\'els in the south polar region for close to
four decades, first disco\'ercd the antarctic ozone hole in 198;. \Vriting in the August issue
of Natllre, BAS researcher Dr. Anna Joncs noted that international co-operation offers the
only real hope for reco\'ery of the atmosphere.
"Ir is only because of restrictions of the Montreal Protocol and its Amendments,
controlling chlorine and hromine emissions that we can expect the Antarctic ozone hole to
disappear," she obser\'es. "Enn though these controls arc coming into cHect, the o:one hole
is likely to appear for many decades."

Toward a Policy for

Northern
Contaminants
The Commi ion ha tres ed the need for
the federal govemment ta tate clearly a
national commitment and obligati n ta
polar science. The members of the
Commi ion believe mat, without uch an
undertaking, Canada' ArC[ic and
Antarctic research program will be unable
ta. u tain the 1 n 'tem1, high,quality
l'
ence CUITent problems demand.
ln the pring of 1995, the Commi ion
relea ed a paper idenrifying prioritie for the
developmenr of a national policy for polar ci­
ence and technology. Toward a Poliey for
Canadian Polar Science and Technology wa
developed with input from polar researcher ,
ab riginal oroanization, and governmenr
agencies across the country.
In the mon th ta come, the
Commission will be pre ing governmenr
departmenrs and agencie ta set ut clearly a
federal po ition n lar sei n e and establish
an inrerdepartmenral council for the co­
ordination of polar science activities acro s
federal Jeparrmenr and agencie. The
Commi 'ion could erve as a con ultative
body ta the council.
