Dataset Overview | National Centers for Environmental Information (NCEI)

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 during 2019 (NCEI Accession 0198947)

Preview graphic

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 NOAA Ship Gordon Gunter cruises in the Gulf of Mexico and North Atlantic Ocean from 2019-05-08 to 2019-11-12. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer and shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
