R/V Simon Stevin Coastal Carbon and Surface Ocean Measurements

NCEI Accession 0208603 contains surface underway data from the R/V Simon Stevin's 2019 cruises in the North Sea and English Channel. The dataset includes measurements of the partial pressure of carbon dioxide in both the atmosphere and water, alongside sea surface salinity, temperature, and barometric pressure. Data were collected using a CO2 gas analyzer and barometric pressure sensor.

Use Cases

• Calculating air-sea CO2 flux based on paired atmospheric and aquatic pCO2 measurements.
• Analyzing seasonal variability in coastal carbon parameters from January to July 2019.
• Correlating sea surface temperature and salinity with pCO2 levels in the North Sea.
• Validating regional ocean carbon models using in-situ surface underway data.

Strengths

• Data collection spans a defined six-month period from 2019-01-10 to 2019-07-29.
• Includes paired measurements for key carbon cycle variables (pCO2 in air and water).
• Dataset is hosted by NOAA and appears on multiple authoritative platforms (Data.gov, NASA Earthdata).

Limitations

• Column names and exact data structure are not provided in any source description.
• Sources conflict on the 'last updated' date (2019-07-29 vs. 2026-03-05).
• Dataset size (rows, file size) and specific license information are unknown.
