Partial pressure of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during the Ship of Opportunity (SOOP) M/V Las Cuevas cruises in the North Atlantic Ocean, Gulf of Mexico, Caribbean Sea and Mediterranean Sea in 2010 (NCEI Accession 0222124)

This dataset consists of the surface underway measurements of mole fraction of CO2 in the equilibrator headspace (dry) at equilibrator temperature (ppm), mole fraction of CO2 measured in dry outside air (ppm), mole fraction of CO2 in outside air associated with each water analysis, barometric pressure in the equilibrator headspace (hPa), barometric pressure, corrected to sea level (hPa), water temperature in equilibrator, sea surface temperature, sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity (uatm), fugacity of CO2 in air corresponding to the interpolated xCO2 at SST and 100% humidity (uatm), sea water fCO2 minus interpolated air fCO2 (uatm). The measurement were performed during the Ship of Opportunity (SOOP) M/V Las Cuevas cruises in the North Atlantic Ocean, Gulf of Mexico, Caribbean Sea and Mediterranean Sea from 2010-01-30 to 2011-01-04.
