The Eurasian Basin, is one of the two major basins into which the North Polar Basin of the Arctic Ocean is split by the Lomonosov Ridge, the other big basin is the Amerasian Basin. The Eurasian Basin may be seen as an extension of the North Atlantic Basin through Fram Strait. It is further split by the Nansen-Gakkel Ridge into the Nansen Basin and the Amundsen Basin. The latter basin is the deepest one of the Arctic Ocean and the geographic North Pole located there.
