  abstract = {{I}n this study, a high-resolution (approximate to 2.5 km) numerical model was set up to investigate the fine-scale activity within the region of the {M}arquesas archipelago. {T}his has never been performed before. {T}he robustness of the model results is assessed by comparison with remote sensing and in situ observations. {O}ur results highlight regions of warm waters leeward of the different islands with high eddy kinetic energy ({EKE}) on their sides. {T}he analysis of energy conversion terms reveals contributions to {EKE} variability by wind, baroclinic, and barotropic instabilities. {T}he use of a geometry-based eddy detection algorithm reveals the generation of cyclonic and anticyclonic eddies in the wake of the largest islands, with both an inshore and offshore effect. {M}aximum eddy activity occurs in austral winter following the seasonality of both wind stress and {EKE} intensity. {M}ost eddies have a radius between 20 and 30 km and are generally cyclonic rather than anticyclonic. {S}ignificant vertical velocities are observed in the proximity of the islands, associated with topographically induced flow separation. {E}ddy trapping inshore waters are advected offshore in the wake of the islands. {T}he overall influence of these fine-scale dynamics could explain the strong biological enhancement of the archipelago.},
