Arctic Ocean The Arctic Ocean occupies a roughly circular basin and covers an area of about 14,056,000 km2 (5,427,000 sq mi), almost the size of Antarctica.[8][9] The coastline is 45,390 km (28,200 mi) long.[8][10] It is surrounded by the land masses of Eurasia, North America, Greenland, and by several islands.
Black Sea The Black Sea is a body of water and marginal sea of the Atlantic Ocean between Eastern Europe and Western Asia.[1] It is supplied by a number of major rivers, such as the Danube, Dnieper, Rioni, Southern Bug, and Dniester. The Black Sea has an area of 436,400 km2 (168,500 sq mi) (not including the Sea of Azov),[2] a maximum depth of 2,212 m (7,257 ft),[3] and a volume of 547,000 km3 (131,000 cu mi).[4] It is constrained by the Pontic Mountains to the south and by the Caucasus Mountains to the east, and features a wide shelf to the northwest. The longest east-west extent is about 1,175 km (730 mi).
