The Caspian Sea or Mazandaran Sea is a landlocked endorheic sea between Asia and Europe (European Russia). It is the world's largest inland body of water. It has a surface area of 371,000 kmē (143,000 sq. mi.), and a maximum depth of about 980m (3200 ft). Thus it has characteristics common to both seas and lakes. It is often listed as the world's largest lake, though it is not a freshwater one. The Caspian Sea is bordered by Russia (Dagestan, Kalmykia, Astrakhan Oblast), Republic of Azerbaijan, Iran/Persia (Guilan, Mazandaran and Golestan provinces), Turkmenistan (Balkan Province), and Kazakhstan, with the central Asian steppes to the north and east. On its eastern Turkmen shore is a large embayment, the Kara Bogaz Gol. The sea is connected to the Sea of Azov by the Manych Canal. The Caspian has characteristics common to both seas and lakes. It is often listed as the world's largest lake, though it is not a freshwater lake. The Volga River (about 80% of the inflow) and the Ural River discharge into the Caspian Sea, but it is endorheic, i.e. there is no natural outflow (other than by evaporation). Thus the Caspian ecosystem is a closed basin, with its own sea level history that is independent of the eustatic level of the world's oceans. The Caspian became landlocked about 5.5 million years ago. The level of the Caspian has fallen and risen, often rapidly, many times over the centuries. Some Russian historians claim that a medieval rising of the Caspian caused the coastal towns of Khazaria, such as Atil, to flood. Over the centuries, Caspian Sea levels have changed in synchronicity with the estimated discharge of the Volga, which in turn depends on rainfall levels in its vast catchment basin. Precipitation is related to variations in the amount of North Atlantic depressions that reach the interior, and they in turn are affected by cycles of the North Atlantic Oscillation. Thus levels in the Caspian sea relate to atmospheric conditions in the North Atlantic thousands of miles to the north and west
