Мировой океан
The global, interconnected body of salt water is sometimes referred to as the "World Ocean" or global ocean. The concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to oceanography. The contemporary concept of the "World Ocean" was coined in the early 20th century by the Russian oceanographer Yuly Shokalsky to refer to the continuous ocean that covers and encircles most of Earth.
