PopSci reported a few months ago on a map from Durham University researchers, showing the complicated web of conflicting arctic claims. At least six nations could own part of the arctic. Under the United Nations Convention on the Law of the Sea (what a mouthful), nations own the rights 200 meters out from the edge of their continental shelf—not the exposed coast, but the undersea lip of the continent. Unfortunately, there is no geophysical consensus on where those shelf edges are, hence this joint voyage.
The U.S. ship, the U.S. Coast Guard cutter Healy will use a multi-beam echo sounder to map the sea floor, sending out sound pulses, which return at different times depending on the depth. The Canadian ship, the Louis S. St. Laurent will follow doing complementary measurements of the sub-sea floor. The hope is that the whole of the arctic does not in fact belong to Russia, and that we, or Canada might own a piece of the pie as well. Go team.
