From a legal perspective, the study is to determine where the outer limit of Canada's continental shelf is, not only in the Arctic but on the other coasts as well. This process is very science driven. In relatively simple terms, the 200 nautical mile zone is the 200 nautical mile zone. You take a ruler—although that's oversimplifying it—and you go and measure it.
The outer limit of the continental shelf is determined by a combination of sedimentary thickness, foot of slope points, 60 nautical miles from the foot of slope points, 1% sedimentary thickness backwards, plus a number of constraint lines. It is a very science-driven process; hence, the project that's ongoing aims to acquire and interpret the scientific information in the Arctic and thereby enable us to submit our information to something called the Commission on the Limits of the Continental Shelf.
They are a science body set up under the law of the sea convention and will review, in time, the Canadian submission. They'll make recommendations, and then the Canadian government will look at these recommendations and do what it thinks is appropriate in light of the recommendations that have been given.
