Partial pressure (or fugacity) of carbon dioxide, salinity and other variables collected from underway - surface observations using Carbon dioxide (CO2) gas analyzer, Thin film type equilibrator for autonomous carbon dioxide (CO2) measurement and other instruments from the MARION DUFRESNE in the Indian Ocean from 2012-01-25 to 2012-03-07 (NCEI Accession 0116411)

This dataset includes biological, chemical, meteorological, physical and underway - surface data collected from MARION DUFRESNE in the Indian Ocean from 2012-01-25 to 2012-03-07 and retrieved during cruise 35MF20120125. These data include BAROMETRIC PRESSURE, FLUORESCENCE, Partial pressure (or fugacity) of carbon dioxide, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include 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 University (SU) as part of the OISO_21 dataset.
