During the cruise multiple near-real-time satellite-derived products provided by AVISO andCLS were used during the cruise to generate daily maps of SST, surface chlorophyll a concentrationand Lagrangian diagnostics allowing to identify fronts, eddies and filaments. This allowed to guidesuccessfully the in situ sampling strategy. This adaptive strategy reveals to be a success as 3contrasted region were sampled during the cruise. For post-cruise analyses we use specificallydesigned high resolution regional altimetric products produced by CLS (with support from CNES).Preliminary results show that the addition of the Ekman component considerably increase theagreement between the satellite product and the trajectories of SVP (Surface Velocity Program)floats. At submesoscale, Lagrangian diagnostics such as Finite Size Lyapunov exponents, calculatedwith altimatric products, allow to detect physical fronts which generally match with in-situ surfacetracer gradients. %G English %L hal-01400972 %U https://hal.science/hal-01400972 %~ CEA %~ INSU %~ MNHN %~ UNIV-BREST %~ UNIV-PARIS7 %~ X %~ ENS-PARIS %~ UPMC %~ UNIV-TLN %~ CNRS %~ UNIV-AMU %~ CNES %~ IFREMER %~ IUEM %~ X-DEP %~ THESES_IUEM %~ MIO %~ OSU-INSTITUT-PYTHEAS %~ GIP-BE %~ LOCEAN %~ UVSQ %~ PEPS %~ PSL %~ USPC %~ UNIV-PARIS-SACLAY %~ UVSQ-SACLAY %~ X-SACLAY %~ LOPS %~ UPMC_POLE_3 %~ CMM %~ SORBONNE-UNIVERSITE %~ SU-INF-2018 %~ SU-SCIENCES %~ FR-636 %~ UNIV-PARIS %~ UP-SCIENCES %~ ENS-PSL %~ MIO-OPLC %~ UVSQ-UPSACLAY %~ ALLIANCE-SU %~ IPSL_LOCEAN
