NCEI 0157381: Surface Ocean Carbon Dioxide Measurements from BARCELONA EXPRESS

NCEI Accession 0157381 contains surface underway chemical, meteorological, and physical data collected from the vessel BARCELONA EXPRESS across the North Atlantic Ocean, Gulf of Mexico, and Mediterranean Sea from February to October 2013. The dataset, produced by NOAA's Atlantic Oceanographic and Meteorological Laboratory, includes measurements of the partial pressure of carbon dioxide in air and water, salinity, sea surface temperature, and barometric pressure. These data were collected using a Carbon dioxide (CO2) gas analyzer and are associated with eight specific research cruise identifiers.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Monitoring ocean acidification trends in the Mediterranean Sea and Gulf of Mexico.
• Validating satellite-derived sea surface temperature and salinity products with in-situ measurements.
• Studying seasonal variability of surface ocean carbon parameters across multiple basins.

Strengths

• Data covers a wide geographic area spanning the North Atlantic Ocean, Gulf of Mexico, and multiple Mediterranean sub-basins.
• Includes measurements from eight distinct research cruises conducted over an eight-month period in 2013.
• Dataset is hosted on multiple authoritative platforms (NASA Earthdata, Data.gov), indicating established provenance.

Limitations

• Column names and the exact number of data rows are not provided in the available metadata.
• Conflicting 'last updated' dates exist between sources (2013-10-08 vs. 2026-03-05), creating uncertainty about metadata maintenance.
• License information is not specified.
