  abstract = {{I}n this study, we report the distributions of total dissolvable cadmium and particulate cadmium from 27 stations in southern {M}oroccan coastal waters (22 degrees {N}-30 degrees {N}), which is part of the {N}orth-{W}est {A}frican upwelling system. {T}hese distributions were predominantly controlled by upwelling of the {N}orth {A}tlantic {C}entral {W}aters ({NACW}s) and uptake by primary production. {A}tmospheric inputs and phosphogypsum slurry inputs from the phosphate industry at {J}orf {L}asfar (33 degrees {N}), recently estimated as an important source of dissolved cadmium (240 t {C}d yr(-1)), are at best of minor importance for the studied waters. {O}ur study provides new insights into the mechanisms fractionating cadmium from phosphate. {I}n the upper 30 m, the anomalies observed in terms of {C}d:{P} ratios in both the particulate and total dissolvable fractions were related to an overall preferential uptake of phosphate. {W}e show that the type of phytoplanktonic assemblage (diatoms versus dinoflagellates) is also a determinant of the fractionation intensity. {I}n subsurface waters (30-60 m), a clear preferential release of {P} (versus {C}d) was observed indicating that remineralization in {O}xygen {M}inimum {Z}ones is a key process in sequestering {C}d.},
