Types of Mediterranean seas

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 Red Sea **The Persian Gulf **The Eurafrican Mediterranean Sea is also a concentration basin as a whole, but the Black Sea and the Adriatic Sea are dilution basins (see below) owing to the
