Partial pressure of carbon dioxide, temperature, salinity and other variables collected from the coastal surface underway observations from NOAA Ship Henry B. Bigelow in the North Atlantic Ocean, US North-East Coast in 2021 (NCEI Accession 0235184)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2021-11-19T00:00:00.000+00:00
This dataset includes surface underway, chemical, meteorological and physical data collected from NOAA Ship Henry B. Bigelow in the North Atlantic Ocean, US North East Coast in 2021. These data include measurements of mole fraction of carbon dioxide (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 fugacity of CO2 (fCO2) and interpolated air fCO2. The instruments used to collect these data include carbon dioxide gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide measurement. In February 2011, the Ocean Carbon Group at NOAA's Atlantic Oceanographic and Meteorological Laboratory (AOML) installed an instrument to measure CO2 levels in surface water and air on NOAA Ship Henry B. Bigelow. The Bigelow primarily operates in the North Atlantic Ocean between North Carolina and Maine.
