Objective The EGEE project (Gulf of Guinea climate and ocean circulation study, which is the oceanographic strand of the AMMA -African Monsoon Multidisciplinary Analyses program) general objective is to study variability in the upper layers of the Gulf of Guinea (GG). It emphasizes ocean-atmosphere interface exchanges, through joint use of in situ and satellite measurements and numerical model results, as well as sub-surface ocean circulation which greatly conditions the way surface layers evolve. To meet the program's aims the 6 EGEE cruises will be used to acquire in situ hydrological and current measurements in the upper layers of the ocean as well as meteorological measurements. They will also allow the maintenance of the PIRATA ATLAS buoy network which is also needed for studies on air-sea exchanges in the Gulf of Guinea. The overall project is AMMA (African Monsoon Multidisciplinary Analyses).
