Partial pressure of carbon dioxide (pCO2), temperature, salinity and other variables collected from surface underway and time series coastal observations from R.V Gulf Challenger in the North Atlantic Ocean, Gulf of Main in 2021 (NCEI Accession 0245678)

This dataset includes surface underway, chemical, meteorological, physical and time series coastal data collected during R/V Gulf Challenger cruises in the North Atlantic Ocean, Gulf of Main from 2021-01-14 to 2021-11-08. These data include air temperature, barometric pressure, partial pressure (or fugacity) of carbon dioxide (pCO2) in atmosphere, pCO2 in water, sea surface salinity, sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
