Arctic Ocean over the Arctic Ocean (see Polar route). The Arctic Ocean occupies a roughly circular basin and covers an area of about , almost the size of Antarctica. The coastline is long. It is surrounded by the land masses of Eurasia, North America, Greenland, and by several islands. It is generally taken to include Baffin Bay, Barents Sea, Beaufort Sea, Chukchi Sea, East Siberian Sea, Greenland Sea, Hudson Bay, Hudson Strait, Kara Sea, Laptev Sea, White Sea and other tributary bodies of water. It is connected to the Pacific Ocean by the Bering Strait and to the Atlantic Ocean through the
Beaufort Sea Pipeline, but is limiting regular commercial production at Mackenzie River deposits. For example, the Amauligak Project was started soon after the discovery of the field. In September 1985, the tanker "Gulf Beaufort" has transported of crude oil to Japan, which was the first shipment of oil from the Arctic deposits. However, the project has stalled after that. In July 2017, the U.S. Bureau of Ocean Energy Management approved a plan to allow Eni, an Italian multinational oil and gas company, to drill four oil exploration wells on Spy Island, one of four artificial islands in the Beaufort Sea.
