  abstract = {{A} remarkable chlorophyll-a concentration ({C}hl, a proxy of phytoplankton biomass) plume can be noticed on remotely sensed ocean color observations at the boundary separating the equatorial mesotrophic from the subtropical oligotrophic waters in the central {S}outh {P}acific {O}cean. {T}his prominent biological feature is known as the island mass effect of the {M}arquesas archipelago. {W}aters surrounding these islands present high macronutrient concentrations but an iron depletion. {I}n this study, the origin of {C}hl enhancement is investigated using a modeling approach. {F}our simulations based on identical physical and biogeochemical forcings but with different iron sources are conducted and analyzed. {O}nly simulations considering an iron input from the island sediments present similar patterns (despite being too weak) of vertical and horizontal {C}hl distributions as compared to biogeochemical-{A}rgo profiling float and satellite observations. {I}n addition, simulations with no other iron input than the boundary forcings reveal the relative importance of remote processes in modulating the seasonal pattern of {C}hl around the archipelago through horizontal advection of nutrient-rich waters from the equator toward the archipelago and vertical mixing uplifting deep nutrient-rich waters toward the upper lit layer.},
