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

NOAA's National Oceanic and Atmospheric Administration collected surface underway chemical, meteorological, and physical data from the R/V F.G. Walton Smith in 2023. The dataset includes air-sea difference of partial pressure of carbon dioxide (pCO2), pCO2 in atmosphere and water, barometric pressure, sea surface salinity, and temperature. These measurements are part of the Global Coastal Carbon Data Project, focusing on carbon cycle understanding on continental margins.

Use Cases

• Modeling coastal carbon dioxide fluxes based on air-sea pCO2 difference data.
• Analyzing correlations between sea surface salinity, temperature, and carbon dioxide levels.
• Studying seasonal or spatial variability of carbon parameters in the Gulf of Mexico and North Atlantic.
• Calibrating or validating satellite-derived ocean carbon measurements with in-situ underway data.

Strengths

• Data collected in 2023, providing recent observations.
• Includes multiple related variables (pCO2, salinity, temperature, barometric pressure) for integrated analysis.
• Part of the structured Global Coastal Carbon Data Project focusing on continental margins.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific cruise tracks in the Gulf of Mexico and North Atlantic.
