Thank you.
I want to switch briefly to Professor McDorman.
Professor, in response to a question from my colleague on the other side, you mentioned the relatively minor dispute between Canada and the U.S. over the 200-mile zone. You're probably aware that the Government of Canada is undertaking a $40 million study over four years to determine the extent of the Canadian continental shelf.
Can you fill us in a little bit on why that's important and what's being done in that study, if you know about it?
