Coastal Upwelling in the Northwestern Gulf of Guinea
Abstract:Previous investigators have concluded that upwelling occurs in the northwestern Gulf of Guinea during the late northern summer months. Some investigators have qualitatively related the seasonal upwelling to average conditions in the wind field. A distinction is made in this paper between “wind-driven” and “current-induced” upwelling, and the role of each is delineated as it relates to the oceanic conditions in the northwestern Gulf of Guinea. Wind-driven upwelling is found to be a seasonal supplement to the current-induced upwelling that is present most of the time. The ecological significance of the two types of upwelling and of advection in superthermocline waters is discussed and its relation is shown to biological data obtained on three cruises of the R/V Geronimo.
