  abstract = {{S}atellite data (images of sea surface temperature and chlorophyll-a), ocean surface wind products, {L}agrangian observations (surface drifters) and other ancillary data (upwelling index) are used to describe the upwelling seasons off {NW} {A}frica during 2009-2013, with particular focus on the coasts of {S}enegal and {M}auritania. {T}he impact of the upwelling is characterised by a comparative analysis, carried out in terms of wind-induced upwelling and water/ecosystem response to this forcing, of five geographical sectors detected in the study area. {T}he wind forcing analysis shows the most favourable upwelling conditions in the period {D}ecember-{J}une in the southern sectors (south of 16 degrees {N}), and from {F}ebruary to {O}ctober in the northern sectors (north of 18 degrees {N}). {S}outhern sectors are strongly influenced by wind forcing, whereas to the north the upwelling also occurs during the months with low {E}kman transport values. {T}he analysis of the sea surface temperature and chlorophyll-a concentration confirms the existence of an upwelling season during winter-spring in the south, and emphasizes the different behaviours between the northern and southern sectors. {D}rifter tracks allow the addition of details about the flow of cold water offshore and alongshore. {I}n particular, they describe the westward transport of cold water, by means of energetic filaments rooted at specific locations along the coast, north of {C}ape {V}ert and the south-{SW} ward transport of the coastal water south of {C}ape {V}ert.},
