The Norwegian Sea ((ノルウェー語:Norskehavet)) is a marginal sea in the North Atlantic Ocean, northwest of Norway. It is located between the North Sea (i.e. north of the United Kingdom) and the Greenland Sea and adjoins the North Atlantic Ocean to the west and the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the North, the Jan Mayen Ridge separates it from the Greenland Sea. Unlike many other seas, most of the bottom of the Norwegian Sea is not part of a continental shelf and therefore lies at a great depth of about two kilometres on average. Rich deposits of oil and natural gas are found under the sea bottom and are being explored commercially, in the areas with sea depths of up to about one kilometre. The coastal zones are rich in fish that visit the Norwegian Sea from the North Atlantic or from the Barents Sea (cod) for spawning. The warm North Atlantic Current ensures relatively stable and high water temperatures, so that unlike the Arctic seas, the Norwegian Sea is ice-free throughout the year. Recent research has concluded that the large volume of water in the Norwegian Sea with its large heat absorption capacity is more important as a source of Norway's mild winters than the Gulf Stream and its extensions.〔(Westerly storms warm Norway ).

A line joining the southernmost point of West Spitzbergen to North Cape of Bear Island, through this island to Cape Bull and thence on to North Cape in Norway (71°10'N 25°47'E). ::''On the Southeast.'' The West coast of Norway between North Cape and Cape Stadt (). ::''On the South.'' From a point on the West coast of Norway in Latitude 61°00' North along this parallel to Longitude 0°53' West thence a line to the NE extreme of Fuglö () and on to the East extreme of Gerpir () in Iceland. ::''On the West.'' The Southeastern limit of Greenland Sea (line joining the southernmost point of West Spitzbergen to the Northern point of Jan Mayen Island, down the West coast of that island to its Southern extreme, thence a Line to the Eastern extreme of Gerpir () in Iceland ). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Norwegian Sea」の詳細全文を読む スポンサード リンク
