  abstract = {{W}e used a coupled physical-biogeochemical model to investigate how the strong eddy activity typical of the {M}ozambique {C}hannel affects biological production. {A} numerical experiment was carried out, in which mesoscale dynamics were suppressed by cancelling the nonlinear terms for horizontal momentum in the {N}aviers-{S}tokes equation. {M}esoscale dynamics were found to be responsible for (1) increased offshore production in the {M}ozambique {C}hannel as a result of net eddy-induced offshore transport of nutrient-rich coastal waters; (2) decreased shelf production along the central {M}ozambican and south-west {M}adagascar coast caused by a reduction in nutrient availability related to the net eddy-induced lateral transport of nutrients; (3) increased coastal production along the northern {M}ozambican coast caused by eddy-induced nutrient supply. {T}he model results also showed an intensification and shallowing of the subsurface production, related to increased upper layer nutrient concentrations caused by eddy activity. {I}n addition, by driving the detachment of the {E}ast {M}adagascar {C}urrent at the southern tip of the island, inertial processes intensify the southern {M}adagascar upwelling and causes offshore diffusion of the upwelled waters. {T}hese results emphasize the complex role played by eddy activity and, more generally, inertial processes on marine ecosystems in this region.},
