Objective The project's general aim was to study variability in the upper layers of the Gulf of Guinea waters (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 fulfil the programme's objectives, 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 array which is also needed for studies on air-sea exchanges in the Gulf of Guinea. The overall project is AMMA (African Monsoon Multidisciplinary Analyses).
