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 ice cover transforms into drifting ice having the thickness of 2–3 m. The southern winter winds shift this ice northwards, making polynyas near the sea centre. There are no icebergs in the sea. Ice melting typically starts around May, first around the delta of the major Kolyma River. In absence of industry, sea water is rather clean. Minor contaminations are found near the Novosibirsk and Wrangel islands (up to 80 µg/L), due to occasional oil spills, and in Chaunskaya Bay due to the local thermal power station and activities at the major port Pevek.
