. The Diversity of the Seas: a regional approach. WCMC Biodiversity Series 4. EAST AFRICA Comoros, Kenya, Madagascar, Mozambique, Reunion and dependencies (to France), Seychelles, Somalia, Tanzania, Mauritius, Mayotte (to France) LARGE MARINE ECOSYSTEMS The mainland sector of the East Africa Regional Seas area includes all of the Somali Coastal Current LME and much of the Agulhas Current LME. Somali Coastal Current. This LME, extending over some 50 million knr, is one of the world's largest. It is based on the Somali Current - a typical Western Boundary Current (a surface current along an eastern continental margin). The South Equatorial Current flows from east to west throughout the year; on approaching the east coast of Africa it divides into the north-flowing East Africa Coastal Current and the south- flowing Mozambique Current. During the southern monsoon (April-October), the northern sector of the East Africa Coastal Current (the Somali Current) continues to flow north at speeds up to 7 knots. This flow, combined with strong offshore winds generates major upwelling of cold waters along the northern Somali coast (the Ras Hafun upwelling). During the northern monsoon (November-March) the Somali Current reverses to flow southward. The phenomena of upwelling and seasonal current reversal are associated with high fishery productivity. Agulhas Current This major Western Boundary Current is a product of the Mozambique Current (see above) flowing south between Madagascar and mainland Africa, and the Madagascar Current, flowing south down the eastern coast of Madagascar. The Agulhas Current is fast and warm (rarely below 21 °C), and flows south throughout the year. It appears to be less productive than eg. the Somali Current system but has high fish diversity. South Africa is not within the Eastern Africa Regional Seas area, but its entire east coast is subject to the effects of the Agulhas Current.
