Caspian Sea

The Caspian Sea lies to the east of the Caucasus Mountains and to the west of the vast steppe of Central Asia.

The Caspain Sea is the world’s largest inland body of water and the world's largest salt lake.

The Caspian Sea is bordered by five countries: Kazakhstan, Turkmenistan, Iran, Azerbaijan, and Russia.

The salinity of the Caspian Sea is about 12.8 parts per thousand on average, going from a mere 1 part per thousand near the Volga outlet to a high of 200 parts per thousand in the Kara-Bogaz-Gol, where intense evaporation occurs. In the open sea, distribution of salinity is markedly uniform; from the surface to the bottom it increases by only 0.1 to 0.2 part per thousand.

The Caspian Sea contains as many as 50 islands, most of them small. The largest are Chechen, Tyuleny, Morskoy, Kulaly, Zhiloy, and Ogurchin.
