This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Sonne cruises SO234 and SO235 in the Indian Ocean from 2014-07-10 to 2014-08-08. These data include measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature, mole fraction of CO2 measured in dry outside air, barometric pressure in the equilibrator headspace, barometric pressure, corrected to sea level, water temperature in equilibrator, sea surface temperature, sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.

These data were collected by Tobias Steinhoff of GEOMAR Helmholtz Centre for Ocean Research as part of the R/V Sonne research cruises in the Indian Ocean. The cruise Expedition codes (EXPOCODE) are 06BE20140710 and 06BE20140723.
