second US-Canadian expedition to the Arctic started on Friday.Scientists conduct photo and video, as well as gather materials about the state of the sea and the continental
Currently, it borders and ownership of the shelf are most interested in the United States, Canada and Russia: each country has produced information that underpin its claim to the shelf and all its resources are on.The current mission will work in areas of the north of Alaska to the Mendeleev Ridge and east of the Canadian Arctic Archipelago, and will run until 16 September.
scientists of the two countries will participate in it.On the icebreaker Healy US Coast Guard and the Canadian Coast Guard ship Louis S. St-Laurent, participants will be 41 days to collect data on the seabed and the continental shelf, where, as expected, are the richest deposits of oil and gas.The expedition also will verify and clarify the navigation data, if necessary.
Subject continental shelf accessory has been actively discussed after Russian deep-sea expedition in 2007.The participants set out to prove that the underwater Lomonosov and Mendeleyev ridges are a continuation of the Siberian continental platform, which will allow Russia to claim the shelf.Then when submerged vehicles "Mir-1" and "Mir-2" at the North Pole on the ocean floor was raised Russian flag and taken soil samples and live organisms from a depth of 4 thousand 261 meters.
the summer of 2008, the US sent an expedition to the Arctic.According to the UN Convention on the Law of the Sea 1982, which involved Russia in 1997, the continental shelf includes the seabed and subsoil to the "outer edge of the continental margin" its minimum length of 200 nautical miles from the coast.
Coastal States have the sovereign right to explore and exploit natural resources on the continental shelf.Due to the complexity of determining the outer limits of the extended continental shelf is no country has established such limits.The question of the accessory shelf is not so much scientific value as energy.According to some estimates, conventional fuel reserves in the shelf area reach 5 billion tons.In addition to Russia of their rights to the shelf and may, in practice, getting ready to declare other countries, including Canada and the United States.
If Russia proves that the arctic underwater Lomonosov and Mendeleyev ridges, which extend to Greenland, are a geological extension of its continental shelf, it will qualify for an additional 1.2 million square kilometers in the Arctic and to develop huge oil and gas deposits on thetriangle Chukotka - Murmansk - North pole.
