The Arctic Basin (also North Polar Basin) is an oceanic basin in the Arctic Ocean, consisting of two main parts separated by the Lomonosov Ridge, a mid-ocean ridge between north Greenland and the New Siberian Islands.

It divides the Arctic Ocean into two major basins: the Eurasian Basin on the Eurasian side of the ridge and the Amerasian Basin on the North American side. It rises over 3000 meters above the floors of these basins and at its highest point is about 954 meters below sea level.

2025年1月17日 · The largest subbasin of the Arctic Ocean is the Canada Basin, which extends approximately 700 miles from the Beaufort Shelf to the Alpha Cordillera. The smooth basin floor slopes gently from east to west, where it is interrupted by regions of sea knolls.

Arctic Ocean In Atlantic Ocean: Extent This is because the Arctic basin—which stretches from the Bering Strait across the North Pole to Spitsbergen and Greenland—resembles a semienclosed basin (i.e., it is nearly surrounded by land, receives proportionately large volumes of river discharge and sediments, has an extensive continental margin ...

The Arctic Ocean is the smallest and shallowest of the world's five oceanic divisions. [1] ... The bathymetry of the ocean bottom is marked by fault block ridges, abyssal plains, ocean deeps, and basins. The average depth of the Arctic Ocean is 1,038 m (3,406 ft). [31]

2025年1月17日 · Arctic Ocean, smallest of the world’s oceans, centering approximately on the North Pole. The Arctic Ocean and its marginal seas are the least-known basins and bodies of water in the world ocean as a result of their remoteness, hostile weather, and perennial or seasonal ice cover.

2021年3月24日 · The Arctic Ocean is a circular basin, spanning 5.427 million square miles. It is almost 1.5 times the United States of America 's size, but slightly smaller than Russia. The Ocean is 18,210 feet deep at the deepest point (Mollow Hole), with an average depth of 3,406 feet below the sea surface.

The Arctic Ocean is the shallowest (mean depth 1361 m) and has significantly larger continental shelves than other oceans. The deep central Arctic Ocean Basin consists of four abyssal plains separated by submarine ridges. The abyssal plains make 12 %, while ridges make 16 % of the total area of the Arctic Ocean . Lomonosov Ridge divide the ...

The deep part of the Arctic Ocean consists of two major basins, the Eurasian and Amerasian Basins, which are physically separated by the Lomonosov Ridge with a mean depth of 1,600 m and a sill depth of 1,870 m.

The Arctic Ocean plays two roles in the global ocean circulation — it provides an oceanic pathway between the Pacific and the Atlantic oceans; and it also takes an Atlantic input, modifies it...
