The Black Sea is located between Southeastern Europe and Asia Minor. Nations bordering the body of water include Russia, Georgia, Turkey, Bulgaria, Romania and the Ukraine. The sea connects to the Mediterranean Sea via the Bosporus and the Sea of Marmara.
The Black Sea covers roughly 160,000 square miles and has a maximum depth of 7,364 feet. A number of rivers drain into the sea from the north. The most notable river is the Danube, which runs through parts of 10 countries. While the rivers dilute the water in the sea, a salinity level less than half of that of the ocean limits the marine life the Sea can support. Major cities located along the Black Sea include Istanbul, Odessa, Ukraine and Samsun, Turkey.
