To that end, a comparative box analysis representing homogeneous sub-regions in the NW African upwelling system has been conducted. The sub-regions have been defined using the near-surface horizontal circulation patterns. In each box, we analysed the dynamics of primary productivity and nutrients with regard to advective and diffusive matter fluxes at the boundaries and local biological production and/or uptake. The nature and variability of the matter exported from the coastal margin to the adjacent open ocean were also subsequently depicted. This variability of the primary production may impact the distribution and abundance of fish populations, and their associated fisheries, on a large range of timescales. specialized AFRIQUE DU NORD AFRIQUE DE L'OUEST ATLANTIQUE 030 034 021 ICAWA : International Conference AWA, 5., Lanzarote (ESP), 2018/04/17-20 120 Brehmer Patrice ed. edt IRD Diogoul N. collab. clb IRD Zenk C. collab. clb IRD Vareilles M. de collab. clb IRD Keenlyside N. collab. clb IRD Nascimento J.M. collab. clb IRD Ramos V.
