Caspian Sea - salinity

The Caspian Sea has internal drainage, which means that it does not have an outlet to the World Ocean. All water entering the sea accumulates or evaporates. The sea surface salinity in the sea exhibits a gradient, with the semi-encludes bay of Kara-Bogaz-Gol having the most saline water. This bay was closed between 1980 and 1992.
