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 In

NODC Accession 0116410 includes biological, chemical, meteorological, physical and underway - surface data collected from MARION DUFRESNE in the Indian Ocean from 2013-02-10 to 2013-03-09 and retrieved during cruise 35MF20130210. 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 Universite Pierre et Marie Curie; Institut Pierre Simon Laplace; Laboratoire D'Oceanographie et du Climat: Experimentations et Approches Numeriques as part of the OISO_22 data set.

The Global Volunteer Observing Ship (VOS) Program is coordinated by the UNESCO International Ocean Carbon Coordination Project (IOCCP). International groups from 14 countries have been outfitting research ships and commercial vessels with automated CO2 sampling equipment to analyze the carbon exchange between the ocean and atmosphere.
