Partial pressure of carbon dioxide, temperature, salinity and other variables collected from the coastal surface underway observations from NOAA Ship Gordon Gunter in the Gulf of Mexico and North Atlantic Ocean in 2021 (NCEI Accession 0232539)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 08:57 PM | Dataset Last Updated: October 14, 2021 at 12:00 AM
This dataset includes surface underway 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, and difference between sea water fCO2 and interpolated air fCO2 measured during the NOAA Ship Gordon Gunter cruises in the Gulf of Mexico and North Atlantic Ocean in 2021. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
