Abstract
Six EGEE/AMMA oceanographic cruises were carried out in the Gulf of Guinea during the early and late phases of the West African Monsoon, in 2005, 2006 and 2007. A few recent studies have used in situ data (hydrology, currents) obtained during these cruises along with satellite products in order to describe and analyze the upper ocean conditions during the AMMA Extended Period of Observations, and to better understand their seasonal to interannual variability. Sea surface temperatures, through the equatorial upwelling and the cold tongue, exhibited very different conditions in June-July of each year, and processes responsible for these differences have been researched, through potential relationships with the wind forcing and the zonal currents and undercurrents. The variability of the eastward Equatorial UnderCurrent at 10°W, that feeds the Gulf of Guinea with cold and salty thermocline waters, along with its fate in the east of the Gulf of Guinea, have been described and analyzed, evidencing its source for the mixed layer and westward recirculation north and south of the equator at the thermocline depth level.
