Argo is an international array of 3000 profiling floats that measure temperature and salinity throughout the deep global oceans, down to 2000 m. It is the single most important global in-situ observing system for the Copernicus Marine Service. The present technologic innovations make an evolution of Argo towards new observation missions possible now. In this context, three main objectives are assigned to this task: (1) The extension of the core Argo mission towards the deep ocean, towards biogeochemistry and the development of more cost-effective platforms by testing the implementation of new sensors (e.g. pCO2 optode) [D3.14] [Euro-Argo, UPMC, Ifremer, CNRS, GEOMAR] (2) The production of a consistent Argo and Bio-Argo validated dataset for the Atlantic Ocean [D3.15] with a specific focus on deep CTD and oxygen data [Euro-Argo, NERC-BODC, Ifremer] and chlorophyll a, backscattering and nitrate data [Euro-Argo, NERC-BODC, UPMC, ACRI-ST]. The scientist responsible for this task within Euro-Argo will be also the WP7 co-chair. (3) The development of actions related to the future sustainability of the Bio-Argo and Deep-Argo components of the Argo programme [D3.16; Euro-Argo] by developing international partnership and long-term agreements with the Euro-Argo members for the organization and funding of these new phases of Argo. Ifremer plans to develop an Autonomous System For Argo float Release (ASFAR) that will be able to deploy 4 floats at predetermined date. Included are costs for the ASFAR frame, for acoustic and for Argos transmitters. Additionally, a subcontract aims at integrating the data from the AtlantOS Argo floats within the Coriolis DAC/GDAC and at performing the delayed mode quality control of temperature, salinity and dissolved oxygen concentration data. As Argo floats transmit the observations to shore via satellite links, Euro-Argo will subcontract companies that operate these satellite transfers to retrieve the observation together with the technical information. In particular these companies ensure a 24H/7day service that is mandatory for such platforms.
