Transpolar Drift Stream
Transpolar Drift Stream – one of the major currents of the Arctic Ocean, transporting sea ice from Alaska to Spitsbergen and Greenland, originates in the Chukchi Sea. T.D.S. is formed, first of all, by river flows of Asia and Alaska, causing continuous discharge movement of water and ice, which is supported by inflow of Pacific waters infiltrating through the Bering Strait. This leads to formation of T.D.S., which crosses the Arctic Ocean and heads to the strait between Spitsbergen and Greenland in its western part. T.D.S. ensures directional ice drift used for arrangement of drifting polar stations.
