2018 research cruises by the NOAA Ship Gordon Gunter collected surface underway measurements of carbon dioxide fugacity, mole fraction, and related oceanographic variables. Data includes sea surface temperature, salinity, and the calculated difference between sea water and atmospheric CO2 fugacity. Rik Wanninkhof and Denis Pierrot of NOAA's Atlantic Oceanographic and Meteorological Laboratory gathered this data using a CO2 gas analyzer and equilibrator.
Use Cases
- Calculate air-sea CO2 flux using fugacity of CO2 in sea water and interpolated air fCO2 difference.
- Analyze correlations between sea surface temperature, salinity, and CO2 fugacity in coastal waters.
- Model coastal carbon dynamics using mole fraction of CO2 in equilibrator headspace and barometric pressure data.
- Validate satellite-derived sea surface temperature and salinity products with in-situ measurements.
Strengths
- Data collected during dedicated NOAA research cruises ensuring controlled measurement conditions.
- Includes derived scientific variables like fugacity of CO2 and air-sea difference.
Limitations
- Sample size and spatial resolution are unknown from the description.
- Temporal coverage is limited to the 2018 cruise period.
