This dataset includes continuous sea surface measurements of pCO2, temperature, salinity and atmospheric pressure data during the R/V Marion-Dufresne cruise Clim-EPARSES (EXPOCODE 35MV20190405) in the Indian Ocean and Mozambique Channel from 2019-04-04 to 2019-04-30. The project Clim-EPARSES (PI, Aline Tribollet/LOCEAN-IPSL-IRD) aims at evaluating the impact of global change (warming, acidification) over the last decades on the coral reef ecosystems in the Eparses Islands (Scattered Islands). The project conducted in April 2019 onboard the R.V. Marion-Dufresne (TAAF) included underway sea surface observations of the ocean carbonate properties in the Mozambique Channel, around Eparses Islands and in the Indian Ocean.

This dataset includes surface underway, chemical, meteorological, optical and physical data collected during the R/V Marion Dufresne OISO-16 cruise in the Indian Ocean from 2008-01-05 to 2008-02-05. These data include BAROMETRIC PRESSURE, FLUORESCENCE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Barometric pressure sensor, Carbon dioxide (CO2) gas analyzer and Thin film type equilibrator for autonomous carbon dioxide (CO2) measurement.

This dataset consists of surface measurements of dissolved inorganic carbon (DIC), total alkalinity (TALK), temperature and salinity during the R/V Marion-Dufresne Ocean Indien Service d'Observations - 7 (OISO-07) cruise (EXPOCODE 35MV20010901) in the Atlantic Ocean from 2001-09-01 to 2001-09-12. The OISO program, initiated in 1998, collects measurements of partial pressure of carbon dioxide (pCO2) and associated parameters (temperature, salinity, DIC, TALK, nutrients, chlorophyll and 13C) along the repeated lines of R.V. Marion-Dufresne in the South-Western Indian and Southern Oceans; this coverage is a complement of the International Ocean Carbon Coordination Project (IOCCP). The OISO data are regularly included in international data synthesis projects as Surface Ocean CO2 Atlas (SOCAT) and Global Ocean Data Analysis Project (GLODAP). In August-September 2001, in the frame of the OISO project, the ship conducted cruises in the North Atlantic.

The OISO program (Océan Indien Service d'Observations), initiated in 1998, collects measurements of pCO2 and associated parameters (T, S, DIC, TALK, nutrients, Chl-a, 13C) along the repeated lines of R.V. Marion-Dufresne in the South-Western Indian and Southern Oceans; this coverage is a complement of the international CO2 observing system (IOCCP). The OISO data are regularly included in international data synthesis (SOCAT, GLODAP).
