Surface underway measurements of carbon dioxide, temperature, salinity, and oxygen were collected during R/V Atlantic Explorer cruises in the North Atlantic Ocean. The data collection was conducted by NOAA_NCEI from January 21 to December 18, 2020. It includes chemical and physical parameters from coastal observations.
Use Cases
- Calculate air-sea CO2 flux using mole fraction of carbon dioxide (xCO2) in water and atmosphere alongside barometric pressure and sea surface temperature.
- Analyze seasonal variability in sea surface salinity and temperature across the 2020 cruise track in the North Atlantic Ocean.
- Correlate dissolved oxygen levels with sea surface temperature and salinity to study ocean biogeochemistry.
- Validate sensor performance by comparing equilibrator temperature and pressure readings with other concurrent measurements.
Strengths
- Data collection spans nearly a full year, from 2020-01-21 to 2020-12-18.
- Includes multiple concurrent physical and chemical parameters per observation (e.g., pCO2, temperature, salinity, oxygen).
- Specifies the instruments used, including GO Oceanics Equilibrator and conductivity sensor.
Limitations
- Sample size (row count) and spatial resolution of the underway track are unknown.
- Limited to a single year (2020) and region (North Atlantic Ocean), restricting long-term or global analysis.
- Data completeness and potential gaps during the cruise periods are not specified.
