Measurements of mole fraction of CO2 in the equilibrator headspace, barometric pressure, sea surface temperature, and salinity collected during coastal cruises in 2017. The data were collected by Rik Wanninkhof and Denis Pierrot of NOAA's Atlantic Oceanographic and Meteorological Laboratory using carbon dioxide gas analyzers and shower head equilibrators. Observations were made from NOAA Ship Gordon Gunter in the North Atlantic Ocean, US North-East coast, and Gulf of Mexico.
Use Cases
- Calculate air-sea CO2 flux based on the difference between sea water fCO2 and interpolated air fCO2.
- Analyze spatial and temporal variability of coastal carbon chemistry based on sea surface temperature and salinity measurements.
- Validate regional ocean carbon models using in-situ surface underway observations of CO2 fugacity.
- Study the relationship between barometric pressure and CO2 mole fraction in marine environments.
Strengths
- Data includes multiple directly measured variables such as mole fraction of CO2, barometric pressure, sea surface temperature, and salinity.
- Measurements were collected by named principal investigators from a NOAA laboratory using specified instruments.
- Observations cover multiple distinct geographic regions: the North Atlantic Ocean, US North-East coast, and Gulf of Mexico.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
