List of mediterranean seas by type

There are two types of mediterranean sea.

Concentration basin

A concentration basin has a higher salinity than the outer ocean due to evaporation, and its water exchange consists of inflow of the fresher oceanic water in the upper layer and outflow of the saltier mediterranean water in the lower layer of the connecting channel. * The Eurafrican Mediterranean Sea (a concentration basin as a whole, but the Adriatic Sea and the Black Sea are dilution basins (see below) owing to the
