Canada favors resolution of Canada-US Beaufort Sea joint maritime boundary

Canada and the United States have long agreed to disagree about the location of their shared maritime boundary in the Arctic’s Beaufort Sea. The disputed area involves some 6,250 square nautical miles (21,436-square kilometres) north of the Alaska/Yukon border. Diplomats from both countries consistently describe the disagreement as “well-managed.”
On February 17, 2010, Catherine Loubier, a spokeswoman for Canada’s Department of Foreign Affairs and International Trade, told Canwest News Service that "Canada favours a resolution of the dispute. The issue has been well-managed by Canada and the U.S. and will be resolved on its own merits when both parties are ready to do so."  Speaking of the joint Canadian-U.S. continental shelf mapping cruises in summers 2008 and 2009* she observed: "The information collected so far suggests there may be a potential overlap of the Canadian and U.S. extended continental shelves in this area” and that the "extent of the overlap is not yet known. It may make sense to resolve the maritime boundary and any extended continental shelf overlaps at the same time."

Icebreaking into the Arctic

The USCGC HEALY embarked Barrow, Alaska, in August 2008 to map the US extended continental shelf, or ECS, in the Arctic Ocean (HLY 0805). Healy sailed again from 7 August to 16 September, 2009 (HLY 0905) to continue ECS mapping, joining with the Canadian icebreaker, the Louis S. St.-Laurent. The two vessels mapped together again in 2010 (see HLY1002) and 2011 (HLY1102).

As the only law professor on the science crew, I was along on HLY 0805 and 0905 to better understand
the science behind the legal process that the UN Convention on the Law of the Sea establishes for states making ECS submissions. As to why the US is mapping now, even though it has not yet acceded to the Convention, read on both here, and in the Law of the Sea notes below.

Thanks to
Vermont Law School and especially to Larry Mayer, Director of the University of New Hampshire's Center for Coastal and Ocean Mapping, for making my part in the trip possible.
Thanks, as well, to Adriane Colburn, for opening new windows on and for the deep.
