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 2009-01-04 to 2009-02-09 (NCEI Accession 0108227)

This dataset includes biological, chemical, meteorological, physical and underway - surface data collected from MARION DUFRESNE in the Indian Ocean from 2009-01-04 to 2009-02-09 and retrieved during cruise 35MF20090104. These data include BAROMETRIC PRESSURE, CARBON DIOXIDE - AIR, 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-17 dataset.

The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
