Ocean salinity from satellite-derived temperature in the Antarctic Ocean
Abstract The aim of the MINERVE project (Mesures à l’INterface Eau-aiR de la Variabilité des Échanges de CO 2 ) is to observe and understand the seasonal and interannual variability of the partial pressure of CO 2 ( p CO 2 ) in surface waters using hydrological and biogeochemical data in the Souther...
