Mediterranean sea (oceanography)
A mediterranean sea (//) is, in oceanography, a mostly enclosed sea that has limited exchange of water with outer oceans and with water circulation dominated by salinity and temperature differences rather than winds or tides. The eponymous Mediterranean Sea, for example, is almost completely enclosed by Europe, Asia, and Africa.
List of mediterranean seas
The Mediterranean seas of the Atlantic Ocean
- The namesake Mediterranean Seas, including the Black Sea, the Sea of Azov, the Aegean Sea (including the Thracian Sea and the Sea of Crete), the Adriatic Sea, the Alboran Sea, the Ligurian Sea, the Balearic Sea, the Tyrrhenian Sea, the Ionian Sea, and the Sea of Marmara.
- The Arctic Ocean (or Arctic Mediterranean Sea, which many regard as an ocean)
- The American Mediterranean Sea: the combination of the Gulf of Mexico and the Caribbean Sea.
- The Baltic Sea
- Baffin Bay
The Mediterranean seas of the Indian Ocean
- The Persian Gulf
- The Red Sea
- The Australasian Mediterranean Sea (including the Banda, Sulu, Sulawesi and Java Seas)
Types of Mediterranean seas
There are two types of Mediterranean sea.
- 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.
- A dilution basin has a lower salinity due to freshwater gains such as rainfall and rivers, and its water exchange consists of outflow of the fresher Mediterranean water in the upper layer and inflow of the saltier oceanic water in the lower layer of the channel. Renewal of deep water may not be sufficient to supply oxygen to the bottom.
- The Hudson Bay is so shallow it functions like a huge estuary.
- Having shallow channels and deep basins, the Sea of Japan could form a Mediterranean sea, but the strong currents from the Pacific prevent it from having an independent water circulation.
- The Baltic Sea is a brackish inland sea, alleged to be the largest body of brackish water in the world (other possibilities include the Black Sea).[inconsistent][clarification needed] It occupies a basin formed by glacial erosion.

Mediterranean seas of the Indian Ocean are the Persian Gulf and the Red Sea, and the Australasian Mediterranean Sea, including the Banda, Sulu, Sulawesi and Java Seas, being connected with the Pacific Ocean.
