MeSOLaB is an operational platform for Argo floats trajectory forecasts and hindcasts. In addition to the trajectories computation, the platform allows to process several other diagnostics, such as data sampling along tracks (e.g. satellite surface chlorophyll, mixed layer depth). The trajectory simulations are based on a Lagrangian module applied to global velocity fields provided routinely by Mercator-Ocean. Velocity fields are obtained from the PSY4QV2R2 system with a resolution of 1/12° and a time period extending from J to J+7, and 4 drifting depth are available (100, 200, 400, 1000m).

the «Geoscience Innovation & Development» group, providing a full set of innovative tools to explore and
interact with the trajectories database.

From its last surfacing position, the float is programmed to drift at surface. A sensitive information for logistic and navigation purposes is to anticipate the area of recovery.

Future works :The BioArgoMed dataset will allow an extensive assessment of the Mesolab tool : its skills to support Argo/BioArgo network and float deployments with respect to specific Lagrangian diagnostics (dispersion from trajectories, phenology from density/chla profiles)
