In Sept. 2010, Russia and Norway signed an agreement covering their portions of the continental shelf, specifically forming a mutual zone in the Barents Sea area.
The Russians have a 200 mile exclusive economic zone under the United Nations Convention on the Law of the Sea (1997), covering its Arctic Shelf. Canada, Norway and all maritime nations are signatories.
The coordinates given by K A are well within the Russian economic zone, and in that regard are meaningless. The Russians have rights to explore or lease within their 200 mile exclusive economic zone.

The Russians are claiming shelf rights well beyond the 200 mile boundary, but this is disputed; in any case this extended claim has no bearing on the area considered here. The UN CLOS has asked Russia to submit more data in support of their extended claim.
