The Black Sea is also connected to the Sea of Azov by the Strait of Kerch. The Black Sea has an area of 436,400 km 2 (168,500 sq mi) (not including the Sea of Azov), a maximum depth of 2,212 m (7,257 ft), and a volume of 547,000 km 3 (131,000 cu mi).he Black Sea is a marginal sea and is the world's largest body of water with a meromictic basin. The deep waters do not mix with the upper layers of water that receive oxygen from the atmosphere. As a result, over 90% of the deeper Black Sea volume is anoxic water.
