NCEI Accession 0157264: Celebrity Equinox Surface Underway Carbon Dioxide Measurements

From January 2, 2016, to January 2, 2017, this dataset contains surface underway measurements of carbon dioxide partial pressure and related variables collected aboard the vessel Celebrity Equinox. The data cover multiple seas and basins in the Atlantic Ocean and Mediterranean Sea, including the Caribbean Sea, Gulf of Mexico, and Strait of Gibraltar. Measurements include air-sea difference in carbon dioxide partial pressure, barometric pressure, salinity, and sea surface temperature, collected using a CO2 gas analyzer.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differences.
• Analyzing spatial patterns of sea surface temperature and salinity across multiple ocean basins.
• Validating satellite-derived ocean carbon measurements with in-situ surface underway data.
• Studying seasonal variability of surface ocean carbon parameters in the Caribbean Sea and Gulf of Mexico.

Strengths

• Covers a full year of continuous data collection from 2016-01-02 to 2017-01-02.
• Includes measurements from a wide geographic area spanning over 15 distinct seas and basins.
• Data appears on multiple authoritative platforms (Data.gov, NASA Earthdata), indicating curation and validation.

Limitations

• Key metadata such as row count, file size, and license are not provided by any source.
• Column names are listed as 'unknown', limiting precise understanding of the data structure.
• The last updated date conflicts between sources (2026-03-05 on Data.gov vs. 2017-01-02 on NASA Earthdata).
