The Kara Sea (Russian: Ка́рское мо́ре, Karskoye 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. The word "kara" is derived from kara, which in several Turkic languages means "black" and also symbolizes "north".
