  abstract = {{T}he spatial and seasonal variability of nutrients and chlorophyll in the southern {H}umboldt {C}urrent {S}ystem were assessed using a high-resolution regional ocean circulation model ({ROMS}) coupled to a biogeochemical model ({P}elagic-{I}nteractions {S}cheme for carbon and {E}cosystem {S}tudies; {PISCES}). {T}he simulated nutrients and chlorophyll fields were validated using satellite and in situ observations at a continental shelf time-series station. {T}he annual cycles of modeled chlorophyll and nutrients were consistent with the highest values observed in spring and summer, which is in agreement with enhanced upwelling observations. {C}o-limitation of phytoplankton growth by nutrients and light was analyzed for diatoms, the dominant phytoplankton group in the simulations. {T}he results showed that co-limitation, near the coast, was governed in autumn and winter by light, and by silicate in spring and summer, whereas other nutrients were limiting offshore between {J}anuary and {A}pril. {N}utrient transport in the surface layer was analyzed. {V}ertical advection reflected areas with higher coastal upwelling, and was partly offset by horizontal processes related to eddy-induced transport from the nearshore to the open ocean. {V}ertical mixing was shown to play a key role in replenishing the surface layer with nutrients.},
