Surface underway chemical and physical data collected during R/V Atlantic Explorer cruises in the North Atlantic Ocean in 2022. These data include sea surface temperature, salinity, mole fraction of carbon dioxide (xCO2) in water and atmosphere, and barometric pressure. Instruments used include GO Oceanics Equilibrator, Hart Thermometer, Setra Pressure sensor, and conductivity sensor.
Use Cases
- Model ocean carbon dioxide partial pressure (pCO2) based on xCO2 measurements.
- Analyze sea surface temperature and salinity relationships based on concurrent sensor data.
- Study barometric pressure effects on gas equilibration based on equilibrator pressure data.
- Calibrate carbon flux models based on simultaneous atmospheric and water xCO2 readings.
- Validate surface underway measurement techniques based on instrument specifications.
Strengths
- Data collected during multiple R/V Atlantic Explorer cruises in 2022.
- Includes simultaneous measurements of water and atmospheric carbon dioxide (xCO2).
- Multiple physical parameters measured: temperature, salinity, and pressure.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
