Abstract

Thirty years of data were used to examine the influence of the Rhone River discharge on the spatio-temporal distribution of primary production in the Gulf of Lions. These patterns are characterised for four hydrological provinces: (i) the Gulf of Marseilles, a coastal oligotrophic system exhibiting a typical diatom-based bloom succession; (ii) the mouth and plume of the Rhone River, containing high levels of nutrients, constant levels of chlorophyll a, and a plankton assemblage dominated by nanoflagellates; (iii) the highly productive dilution area to the west of the Rhone, with a diatom spring bloom and smaller winter diatom blooms; (iv) the southern area encompassing the oligotrophic Liguro-Provençal Current, a frontal zone of constantly high primary production and a divergence area exhibiting a typical spring bloom situation. No evidence of eutrophication due to river input was seen. In situ and in vitro net community production data suggest the Gulf of Lions as a whole is a balanced ecosystem on an annual time scale, with the mean primary production lying between 78 and 142 g C m−2 a−1.
