Partial pressure of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during Ships of Opportunity (SOOP) M/V Le Commandant Charcot cruise lines in the Southern Ocean, South Atlantic Ocean, North Atlantic Ocean, Arctic Ocean in 2025 (NCEI Accession 0312635)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: February 28, 2026 | Last Modified: 2026-02-20T00:00:00.000+00:00
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. These values are interpolated between the bracketing averaged good xCO2_ATM analyses (ppm), barometric pressure in the equilibrator headspace (hPa), barometric pressure measured outside, corrected to sea level (hPa), water temperature in equilibrator (°C), sea surface temperature (°C), sea surface salinity, fugacity of CO2 in sea water at SST and 100% humidity (μatm), fugacity of CO2 in air corresponding to the interpolated xCO2 at SST and 100% humidity (μatm), sea water fCO2 minus interpolated air fCO2 (μatm). The measurement were performed during the during Ships of Opportunity (SOOP) M/V Le Commandant Charcot cruise lines in the Southern Ocean, South Atlantic Ocean, North Atlantic Ocean, Arctic Ocean in 2025.
