Mediterranean Sea

The Mediterranean Sea is a part of the Atlantic Ocean almost completely enclosed by land, on the north by Europe, on the south by Africa, and on the east by Asia. It covers an approximate area of 2.5 million km² (965 000 mi²). It is also called the Eurafrican Mediterranean Sea or the European Mediterranean Sea in oceanography to distinguish it from other mediterranean seas in the world.

Geology

The geology of the Mediterranean is complex, involving the break-up and then collision of the African and Eurasian plates, and the Messinian Salinity Crisis in the late Miocene when the Mediterranean dried up.

The Mediterranean Sea has an average depth of 1,500 m and the deepest recorded point is 5267 meters = about 3.27 miles in the Calypso Deep in the Ionian Sea. The coastline extends for 46,000 km. A shallow submarine ridge (the Strait of Sicily) between the island of Sicily and the coast of Tunisia divides the sea in two main subregions (which in turn are divided into subdivisions), the Western Mediterranean and the Eastern Mediterranean. The Western Mediterranean covers an area of about 0.85 million km² and the Eastern Mediterranean about 1.65 million km².

In the last few centuries, humankind has done much to alter Mediterranean geology. Structures have been built all along the coastlines, exacerbating and rerouting erosional patterns. Many pollution-producing boats travel the sea that unbalance the natural chemical ratios of the region. Beaches have been mismanaged, and the overuse of the sea's natural and marine resources continues to be a problem. This misuse speeds along and/or confounds natural processes. The actual geography has also been altered by the building of dams and canals.

The Mediterranean was once thought to be the remnant of the Tethys Ocean. It is now known to be a structurally younger ocean basin known as Neotethys. Neotethys formed during the Late Triassic and Early Jurassic rifting of the African and Eurasian plates.

There have been theories that the Mediterranean reflooded after Man reached the area, causing the Biblical Flood legend. However, the Strait of Gibraltar is too deep to have dried out in the Ice Age, and the Flood legend may recall the Black Sea re-flooding.
