It is a landlocked endorheic body of water and lies between Asia and Europe. It has a maximum depth of about . It is called a sea because when the Romans discovered it they tasted the water and found it to be salty. It has a salinity of approximately 1.2 percent, about a third the salinity of sea water.
Buzachi Peninsula
This peninsula is a vast low-lying depression with salt marshes and salt lakes. Parts of it lie between 20 and 30 m below sea level, lower than the Caspian. The area provides an important habitat for thousands of Goitered Gazelles.
The area was mapped by Fedor Ivanovich Soimonov during the Caspian Expedition, which surveyed the Caspian Sea from 1719 to 1727.
