Última Mise en place d’une nouvelle méthodologie pour la mesure in situ des vitesses verticales océaniques grâce aux données de la campagne FUMSECK 2019 ArchiMer Comby, Caroline. Vertical velocities knowledge is essential to study fine-scale physical processes in the surface layers of the ocean and to understand biological production mechanisms. However, these vertical velocities are often neglected due to mainly two reasons: their order of magnitude (mm.s-1) lower than the one of the horizontal velocities (cm.s-1), and the challenge of this in situ measurement. The FUMSECK cruise, which took place in spring 2019, in the gulf of Genoa, collected in situ measurements of vertical velocities using various instruments, including Acoustic Doppler Current Profilers (ADCP). The analysis of these data, object of this report, required the elaboration of an original processing chain, first developed for the data of the 5th beam of a Sentinel...

In this study, a high-resolution (∼2.5 km) numerical model was set up to investigate the fine-scale activity within the region of the Marquesas archipelago. This has never been performed before. The robustness of the model results is assessed by comparison with remote sensing and in situ observations. Our results highlight regions of warm waters leeward of the different islands with high eddy kinetic energy (EKE) on their sides. The analysis of energy conversion terms reveals contributions to EKE variability by wind, baroclinic, and barotropic instabilities. The 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.
