Northern Sea Route

The Northern Sea Route (NSR) (Russian: Се́верный морско́й путь, romanized: Severnyy morskoy put, shortened to Севморпуть, Sevmorput) is a shipping route about 5,600 kilometres (3,500 mi) long. The Northern Sea Route (NSR) is the shortest shipping route between the western part of Eurasia and the Asia-Pacific region.

Administratively, the Northern Sea Route begins at the boundary between the Barents and Kara Seas (the Kara Strait) and ends in the Bering Strait (Cape Dezhnev). The NSR straddles the seas of the Arctic Ocean (Kara, Laptev, East Siberian and Chukchi Seas).

The entire route lies in Arctic waters and within Russia's exclusive economic zone (EEZ), and is included in what has been called the Northeast Passage, analogous to Canada's Northwest Passage. The Northern Sea Route itself does not include the Barents Sea, and it therefore does not reach the Atlantic.

The Northern Sea Route currently serves the Arctic ports and major rivers of Siberia by importing fuel, equipment, food and exporting timber and minerals. Currently, six major seaports are located on the NSR route in the Arctic Zone of the Russian Federation: Sabetta, Dikson, Dudinka, Khatanga, Tiksi, and Pevek ports. Some parts of the route are only free of ice for two months per year, but melting Arctic ice caps are likely to increase traffic and the commercial viability of the Northern Sea Route. One study, for instance, projects "remarkable shifts in trade flows between Asia and Europe, diversion of trade within Europe, heavy shipping traffic in the Arctic and a substantial drop in Suez traffic. Projected shifts in trade also imply substantial pressure on an already threatened Arctic ecosystem". At the same time, research conducted by the Center for Marine Research showed that exceeding the maximum permissible concentrations in the atmospheric air, sea waters, and bottom sediments, which could indicate the impact of economic activities at this stage of development of the NSR was not recorded.
