The Kara Sea ((ロシア語:Ка́рское мо́ре), ''Karskoe More'') is part of the Arctic Ocean north of Siberia. It is separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and the Laptev Sea to the east by the Severnaya Zemlya archipelago. It is named for the Kara River (flowing into Baydaratskaya Bay), which is now relatively insignificant but which played an important role in the Russian conquest of northern Siberia.〔E.M. Pospelov, ''Geograficheskie nazvaniya mira'' (Moscow, 1998), p. 191.〕 The word "kara" is derived from ''kara'', which in several Turkic languages means "black" and also symbolizes "north". The Kara Sea's northern limit is marked geographically by a line running from Cape Kohlsaat in Graham Bell Island, Franz Josef Land, to Cape Molotov (Arctic Cape), the northernmost point of Komsomolets Island in Severnaya Zemlya. The Kara Sea is roughly 1,450 kilometres long and 970 kilometres wide with an area of around and a mean depth of . Compared to the Barents Sea, which receives relatively warm currents from the Atlantic, the Kara Sea is much colder, remaining frozen for over nine months a year. The Kara receives a large amount of fresh water from the Ob, Yenisei, Pyasina, and Taimyra rivers, so its salinity is variable. Its main ports are Novy Port and Dikson and it is important as a fishing ground although the sea is ice-bound for all but two months of the year. Significant discoveries of petroleum and natural gas, the East-Prinovozemelsky field, an extension of the West Siberian Oil Basin, have been made but have not yet been developed. In 2014, US government sanctions resulted in Exxon having until September 26 to discontinue its operations in the Kara Sea.〔(Sanksjoner kan avslutte boring i Karahavet )〕 ==Geography== 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「Kara Sea」の詳細全文を読む スポンサード リンク
