Arctic resources race The Arctic consists of multiple sub-regions: Russian Arctic, Canadian Arctic, Greenland (Kalaallit Nunaat), Northern Alaska (USA), Svalbard(Norway), Iceland, Fennoscandia. In addition to these sub-regions, the Arctic Ocean and its multiple seas—Greenland Sea, Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea, Chuckchi Sea, Beaufort Sea,etc.-- make the arctic a vast region with a variety of natural resources. The U.S. Geological Survey estimates that undiscovered oil and gas reserves in the Arctic amount to 22% of the world's total, about 412 billion barrels of oil. A Brookings Institution summary reported: The first offshore oil platform in the Arctic was Prirazlomnaya in
Beaufort scale law relating wind velocity to Beaufort force. Wave heights in the scale are for conditions in the open ocean, not along the shore. The wind speeds in different units are not mathematically equivalent; e.g. 12–19 km/h is not equivalent to 8–12 mph, and both are not equivalent to 7–10 knots. The reason is that the Beaufort scale is not an exact nor an objective scale. It was based on visual and subjective observation of a ship and of the sea. The corresponding integral wind speeds were determined later, but the values in different units were never made equivalent. The scale
