Definition
- OISO program (Océan Indien Service d'Observation) was labelised INSU Observation Service in July 1997. Since 1997, this Observation Service is supported by three Institutes (INSU, IPEV and IPSL). This program sets up a network coupled oceanic and atmospheric observations on long time to identify and quantify oceanic CO2 sources and sinks variations , to understand air-sea CO2 exchanges from one season to another, from one year to another, to estimate the evolution of these exchanges in response to climatic changes and to identify carbon anthropic in the ocean and its evolution (bonds with the research programs). In addition to detailed study of CO2 oceanic cycle in Indian and southern south-western zone, the data collected at the time during OISO campaigns are usable to force and to validate oceanic models (e.g. IPSL/IM), the atmospheric models reverse and assimilable in the predictive approaches. The recognition of the responsible processes in CO2 oceanic cycle variations requires a multiannual follow-up and pluridécennal same area. For logistic reasons, choice of a long-term follow-up is fixed on the oceanic zones covered by the ways of Marion-Dufresne rotations in the Indian Ocean, ship chartered by IPEV.
