Partial pressure of carbon dioxide, temperature, salinity and other variables collected fr

National Oceanic and Atmospheric Administration (NOAA) collected surface underway data from R/V Ryofu Maru III cruises in the Pacific Ocean from January to September 2019. The dataset includes measurements of partial pressure of carbon dioxide in water, barometric pressure, sea surface salinity, and sea surface temperature. Instruments used include a carbon dioxide gas analyzer and a shower head chamber equilibrator for autonomous CO2 measurement.

Use Cases

• Modeling ocean carbon uptake based on partial pressure of carbon dioxide measurements.
• Analyzing sea surface temperature and salinity correlations with CO2 levels.
• Studying spatial and temporal variability of surface ocean pCO2 in the Pacific Ocean.
• Calibrating or validating satellite-derived sea surface data with in-situ ship observations.

Strengths

• Data collected over a defined 9-month period from 2019-01-10 to 2019-09-22.
• Includes key variables for carbon cycle studies: pCO2, temperature, salinity, and barometric pressure.
• Provenance is clear, originating from NOAA's Ship of Opportunity Program (SOOP).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific ship track.
