McLaughlin) and the BGEP (Beaufort Gyre Exploration<br />

Project, led by Andrey Proshutinsky) to optimize use of<br />

available resources.<br />

In 2007 and 2008, C3O used two science-capable<br />

icebreakers of the Canadian Coast Guard whose current<br />

mission tracks encircle Canada (Fig. 2.2-8) to obtain a<br />

snapshot of large-scale ocean and ecosystem properties<br />

and thus establish a scientific basis for sustained<br />

monitoring of Canada’s subarctic and arctic seas in the<br />

wake of global warming. C3O collected fundamental<br />

data on temperature, salinity, nutrients, oxygen, the<br />

carbon system, virus, bacteria, phytoplankton, zooplankton,<br />

fish, benthos and whales, with the goal of establishing<br />

connections between the physical environment<br />

and the living nature. The following observations<br />

were made in the two-year period: 551 CTD/rosette<br />

stations; 324 underway CTD and expendable CTD stations;<br />

148 zooplankton net hauls; 64 biological stations<br />

(viral abundance, DNA/RNA, primary production); and<br />

approximately 24,000 km of underway sampling. The<br />

ultimate goal of C3O is to establish a ‘scientific fence’<br />

around Canada with observations that will allow both<br />

observers and modellers to gauge the progress and<br />

consequences of global change and thus provide policy<br />

makers and the Canadian public with information<br />

essential to governance, adaptation and resiliencebuilding<br />

in the Canadian North. Regular repetition<br />

through to 2050 would reveal the expected redistributions<br />

of oceanic boundaries and biomes (Carmack<br />

and McLaughlin; 2001; Grebmeier et al.; 2006) and give<br />

scientists and policy makers access to the time-scales<br />

of change that have the greatest social relevance and<br />

impact. Nevertheless, the value of C3O will not rest entirely<br />

with its own findings. With 26 separate study sites<br />

covering a broad range of disciplines, the ‘connectivity’<br />

of C3O with the results of other major IPY projects can<br />

be expected to be high. These expected yet unpredictable<br />

linkages between project results represent, in<br />

many ways, the unplanned ‘profit’ of IPY, developing a<br />

more thorough and a more complex understanding of<br />

the processes of arctic change than might be evident<br />

from any single project. One emerging example – from<br />

Fig. 2.2-8. The 26 sites<br />

and subjects that are<br />

presently monitored<br />

Canadian C3O<br />

program, designed to<br />

assess the progress<br />

of global change<br />

throughout Canada’s<br />

three oceans.<br />
