Lincoln Sea Lincoln Sea Lincoln Sea (; ) is a body of water in the Arctic Ocean, stretching from Cape Columbia, Canada, in the west to Cape Morris Jesup, Greenland, in the east. The northern limit is defined as the great circle line between those two headlands. It is covered with sea ice throughout the year, the thickest sea ice in the Arctic Ocean, which can be up to thick. Water depths range from to . Water and ice from Lincoln Sea empty into Robeson Channel, the northernmost part of Nares Strait, most of the time. The sea was named after Robert
East Siberian Sea the sea centre, reaching 31–32‰ at its northern outskirts. Salinity decreases in summer by some 5‰ due to the snow melting. It also decreases by some 5–7‰ from the sea bottom to the surface. There are constant currents at the sea surface directed from west to east. They are weak and thus can temporarily change direction due to the wind. The tides are semidiurnal (rising twice a day) with the amplitude between 5 and 25 cm. The tidal wave weakens toward the coast due to shallow waters. The sea level is maximal in summer, due to the river runoff, and
