Somali Current 15 m/s) of the Southwest monsoon affecting the Somali Current induce intense vertical mixing, increasing the thickness of the mixed layer as well as overall surface nutrient enrichment leading to high productivity. After this season, with the onset of the Northeast (Winter) Monsoon, primary productivity decreases, though zooplankton density does so only slightly. Somali Current The Somali Current is an ocean boundary current that runs along the coast of Somalia and Oman in the Western Indian Ocean and is analogous to the Gulf Stream in the Atlantic Ocean. This current is heavily influenced by the monsoons and is the only
Benguela Current ecosystem. Source waters for the Benguela include cold upwelled waters from the depths of the Atlantic Ocean close inshore, joined further off-shore by nutrient poor water that has crossed the Southern Atlantic from South America as part of South Atlantic Gyre. Eddies from the warm South Indian Ocean Agulhas current along South Africa's east coast do round the Cape of Good Hope from time to time to join the Bengulela current. The Benguela current is 200 to 300 km wide and widens further as it flows north and northwest. Its western, seaward edge is well-defined, with many temporary and seasonal
