Variations in sea level for the Caspian Sea (1840-2004)
The Caspian Sea has been endoreic – inwardly draining, without any outlet – since the Pliocene epoch (about 5 million years ago), prompting some specialists to treat it as the world’s largest lake. Studies of its geomorphology and hydrology have revealed alternating cycles of rising and falling water levels, raising many questions, scientific for some, more down-to-earth for those living on the shores.
