4//Inter Press Service News Agency, Italy--ARCTIC: CANADA AND DENMARK REVIVE SOVEREIGNTY CLAIMS (Canada and Denmark launched a joint expedition in early April to map the floor of the Arctic Ocean and help the two countries prove their claims of sovereignty over areas potentially rich in petroleum and natural gas. As the months-long winter darkness lifts in Canada's vast Arctic region, helicopters and airplanes are busy ferrying scientists and seismic survey equipment from the two countries for this project costing 50 to 60 million dollars. No one knows exactly where Canada ends. Its northern boundary has never been mapped because it's covered year round in a blanket of ice five to 10 metres thick. Although located in Northern Europe, Denmark still considers Greenland, the world's largest island and just a few dozen kilometres from Canada's Arctic islands, as Danish territory. … The Arctic is one of the last frontiers, representing about 25 percent of the last unexplored potential oil and gas reserves in the world, says Michael Byers, Canada research chair in Global Politics and International Law at the University of British Columbia, in western Canada.)
