Red Sea

Conshelf II in the Red Sea (Sudan)

The Red Sea (Arabic البحر الأحمر Baḥr al-Aḥmar, al-Baḥru l-’Aḥmar; Hebrew ים סוף Yam Suf; Latin Mare Erythr�um) is a gulf or basin of the Indian Ocean between Africa and Asia. The connection to the ocean is in the south through the Bab el Mandeb sound and the Gulf of Aden. In the north is the Sinai Peninsula, the Gulf of Aqaba and the Gulf of Suez (leading to the Suez Canal). The sea is roughly 1900 km long and at its widest is over 300 km. The sea floor has a maximum depth of 2,500 m in the central median trench and an average depth of 500 m, but it also has extensive shallow shelves, noted for their marine life and corals. The sea has a surface area of roughly 438,000 or 450,000 km�. The sea is the habitat of over 1000 invertebrate species and 200 soft and hard corals. The sea occupies a part of the Great Rift Valley.

Name

The name of the sea does not indicate a real red colour, as the seawater is actually blue when viewed afar, and transparent when held in hand. It may signify the seasonal blooms of the red-coloured cyanobacteria Trichodesmium erythraeum near the water surface. Some suggest that it refers to the mineral-rich red mountains nearby, which are indeed called "הרי אדום" ("Mounts of the Edomites" or "the Rubi mountains") in Hebrew language.

Physical Properties

Surface water temperatures remain relatively constant at 21-25�C and temperature and visibility remain good to around 200 m, but the sea is known for its strong winds and tricky local currents. The sea was created by the division of Africa from the Arabian peninsula, a movement which began around 30 million years ago. The sea is still widening and there are small volcanic features in the deeper parts, it is considered that the sea will become an ocean in time (as proposed in the model of Tuzo Wilson).
