  abstract = {{O}ceanographic in situ data collected in the {G}ulf of {G}uinea during six cruises carried out between 2005 and 2007 were analysed to study the influence of equatorial upwelling on the productivity of the region. {A}t 10°{W}, observations during boreal summer and autumn cruises captured seasonal upwelling influences. {I}n response to the shoaling pycnocline in {J}une 2005, higher concentrations of nitrate and chlorophyll fluorescence were recorded at the ocean surface in {J}une than in {S}eptember. {O}ur findings challenge the paradigm that westward advection from the nutrient-rich {A}frican coast is responsible for equatorial enrichment in the {G}ulf of {G}uinea. {V}ertical sections of the parameters under study in the summer of 2005 showed no westward advection from 3°{E} to 10°{W} within the equatorial band. {T}his emphasizes the important role of vertical processes in equatorial enrichment at 10°{W}. {A}n additional aspect of our study provides evidence of the impact on nutrient and chlorophyll distribution of offequatorial westward recirculation of equatorial undercurrent waters (observed between 2°and 3°{S}).},
