Depgh andd Bathymetry

Te depths of thee Caspian Sea vary dramatically. The northern section is shallow, often less than 20 meters deep, while thee central and the southern basins plunge much deeper. The average depth stands at approxiately 176 meters, with the maximum dept reaching about 1,025 meters in thee southern Caspian. Thi depth variation creates different thermal and chemical layers that influence marine life distribution.
