Objective | The S.O. OISO (Indian Ocean observation service) aims to study the variability over time and space of air-sea exchanges of CO2 and the invasion of anthropogenic CO2 in the ocean in subtropical, sub-Antarctic and Southern Ocean zones. The OISO observations acquired aboard RV Marion-Dufresne (IPEV) since 1998 complement the measurements taken in other ocean sectors by French and foreign partners (http://www.ioccp.org/Underway/). These observations are crucial for assessing carbon budgets on a global scale (Kyoto protocol framework) and to parameterize, then validate, predictive climate models (IPCC framework). The OISO22 aimed to repeat the measurements of CO2 and associated parameters along the logistics track of RV Marion Dufresne. As well as continuous surface measurements, which can be used to assess the air-sea flux, measurements were acquired on the water column at 7 OISO stations located along the return trip between 56°S and Réunion Island, as well as 2 KEOPS stations in the bloom to the East and South of Kerguelen. Plankton foraminifera were also collected in order to assess their role in the biological CO2 pump (SOforCO2 project, led by R. Schiebel). The related programmes are: LEFE/CyBER (National), CLIVAR/WCRP, SOLAS/IMBER/IGBP and FP7/CARBOCHANGE (International). |
