Coastal Carbon and Ocean Physics from Research Vessel Underway Systems

Surface underway measurements from the R/V Healy in the Arctic and North Pacific Oceans (2011-2012) and the USS Bold in the Gulf of Mexico (2007) provide data on the partial pressure of carbon dioxide, salinity, and sea surface temperature. The data were collected using carbon dioxide gas analyzers and shower head equilibrators as part of the Global Coastal Carbon Data Project. These coastal and open ocean measurements support the study of the carbon cycle on continental margins.

Use Cases

• Modeling air-sea carbon dioxide exchange based on underway pCO2 measurements.
• Analyzing correlations between sea surface temperature and carbon dioxide fugacity in coastal waters.
• Studying salinity gradients and their relationship with carbon parameters in the Gulf of Mexico and Arctic Ocean.
• Calibrating and validating satellite-derived sea surface temperature products with in-situ underway data.

Strengths

• Data spans multiple years (2007, 2011-2012) and diverse geographic regions including the Arctic Ocean and Gulf of Mexico.
• Collection used standardized instruments (CO2 gas analyzer, shower head equilibrator) common in ocean carbon research.
• Part of the structured Global Coastal Carbon Data Project, indicating curated data integration.

Limitations

• Column names and exact data structure are not provided in any source, limiting immediate usability.
• Conflicting 'last updated' dates (2007-08-24 vs. 2026-03-06) for the same NODC accession create uncertainty about metadata freshness.
• Row counts and dataset sizes are uniformly unknown across all platform entries.
