National Strategy for Argo Global Network Profiling floats Deployments of Opportunity

To ensure the maintenance of the international Argo network of autonomous profiling float, France is committed to contribute to deploy a significant part of the global network (around 10%). The profiling floats of the Argo-France program are funded by Ifremer and SHOM, supported by the French “Ministère de l’Enseignement Supérieur, de la Recherche et de l’Innovation” funding via the “Très Grande Infrastructure de recherche” (TGIR), “Contrat de Plan État-Région” (CPER), PIA projects such as Equipex NAOS, and CNES. These purchases are part of the Coriolis inter-agency partnership.

Between 50 and 70 T/S type profiling floats (Temperature / Salinity), T / S / DO (Dissolved Oxygen), Deep (Deep) and BGC (Biogeochemical) are purchased each year. A special feature of the Argo-France program is that these profiling floats are then made available to the national scientific community via the annual call for project in the INSU’s LEFE/GMMC framework. Profiling floats that are not assigned to scientific teams as part of this call are deployed via opportunity campaigns.

The purpose of this document is to define the strategy of the Argo-France program to prioritize the deployment zones and the settings of these profiling floats called “deployments of opportunities”. These recommendations are established and motivated by the expertise and historical interest of the French community; and in line with the various international strategies and recommendations of the Argo program (AST, ADMT and Euro-Argo) or emerging projects. By nature, it is therefore intended to evolve over time.
