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 is bordered by the continental shelves of Eurasia and North America.[1][2]
Fridtjof Nansen and Otto Sverdrup sailed the basin in the Fram from 1893 to 1896. Between 1922 and 1924, Roald Amundsen followed in the Maud.
