The
Canadian IPY - Issues and Approaches:
A view from western Canada |
The
Canadian International Polar Year was launched in 2007 with 80% of
the funding to be spent in the first two years of this 5-year program.
In many ways IPY is timely in that the Arctic is undergoing
unprecedented change in ice climate with as yet less clear
consequences for biology and geochemistry. In this talk I will
discuss some of the issues we face in a changing Arctic Ocean and
review the major oceanographic programs that have been funded in
western Canada. These studies, now underway, provide widely disparate
geographical approaches to the issue of change ranging from a greater
than 5000 mile transect across Canada's three oceans to freezing a
ship in for a full seasonal view of shelf polynya processes to
combining moorings and sections to work out how the Arctic Ocean sheds
its fresh water. Equally disparate is the approach to sampling and
the combination of atmospheric, oceanic and biogeochemical components.
IPY will produce a large harvest of data which will require a
commitment for many years down the road. |
