Partial pressure of carbon dioxide, salinity, temperature, and barometric pressure collected from the surface underway observations from R/V Marion Dufresne during the OISO-1, OISO-2 and OISO-3 cruises in the Indian Ocean 1998-01-21 to 1998-12-28 (NCEI Accession 0081003)

NCEI Accession 0081003 includes surface underway, chemical, meteorological, optical and physical data collected from R/V Marion Dufresne during the OISO-1, OISO-2 and OISO-3 cruises in the Indian Ocean 1998-01-21 to 1998-12-28. The data include the partial pressure of carbon dioxide, salinity, temperature, and barometric pressure. 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. These data were collected by Nicolas Metzl of Sorbonne Université/CNRS/IRD/MNHN, Laboratoire d'océanographie et du climat: expérimentation et approches numériques (LOCEAN) as part of the OISO-1, OISO-2 and OISO-3 data set.
