  abstract = {{E}ddies and other mesoscale oceanic processes, such as fronts, can enhance biological production in the ocean, according to several open-ocean studies. {T}he effect is thought to be particularly pronounced in low-nutrient environments, where mesoscale processes increase the net upward flux of limiting nutrients. {H}owever, eddies have been suggested to suppress production in the highly productive eastern boundary upwelling systems. {H}ere, we examine the relationship between satellite-derived estimates of net primary production, of upwelling strength, and of eddy-kinetic energy-a measure of the intensity of mesoscale activity-in the four most productive eastern boundary upwelling systems. {W}e show that high levels of eddy activity tend to be associated with low levels of biological production, indicative of a suppressive effect. {S}imulations using eddy-resolving models of two of these upwelling systems support the suggestion that eddies suppress production, and show that the downward export of organic matter is also reduced. {A}ccording to these simulations, the reduction in production and export results from an eddy-induced transport of nutrients from the nearshore environment to the open ocean. {E}ddies might have a similar effect on marine productivity in other oceanic systems that are characterized by intense eddy activity, such as the {S}outhern {O}cean.},
