Canada filed an addendum on Monday to extend its continental shelf in the Arctic, increasing significantly its overlaps with claims by Russia. The addition is to Canada’s 2019 partial submission that claimed approximately 1.2 million square kilometres of the Arctic Ocean seabed and subsoil. Canada's 2019 submissionThe Lomonosov Ridge is a kind of underwater mountain chain that extends across the seafloor of the Arctic Ocean and is something that Canada, Russia and Denmark all claim is an extension of their respective continental shelves. In June, Canada, Finland, Iceland, Denmark, Norway, Sweden and the United States said they’d resume limited council work in areas that did not include Russia. “During the preparation of this submission, regular consultations between Canada and the Russian Federation revealed overlaps in their respective continental shelves in the Arctic Ocean,” the addendum said.
