Ocean Carbon and Surface Conditions from the Celebrity Equinox

NCEI Accession 0157224 contains surface underway measurements of carbon dioxide partial pressure, salinity, and sea surface temperature collected aboard the vessel Celebrity Equinox. Data collection spanned from February 23, 2015, to January 2, 2016, across multiple seas including the North Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and the Mediterranean Sea. The dataset likely contains time-series records of atmospheric and oceanic carbon dioxide levels, barometric pressure, and related physical variables.

Use Cases

• Calculating air-sea CO2 flux based on the difference between atmospheric and water partial pressure measurements.
• Analyzing spatial patterns of sea surface temperature and salinity across transoceanic routes.
• Validating ocean carbon cycle models with in-situ pCO2 data from a Volunteer Observing Ship.
• Studying seasonal variability of surface ocean chemistry in the Mediterranean Sea and North Atlantic.

Strengths

• Data covers a wide geographic area across the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and Mediterranean Sea.
• Collection period spans nearly a full year (2015-02-23 to 2016-01-02), allowing for seasonal analysis.
• Data originates from a recognized NOAA laboratory (AOML) and is documented under a specific NCEI accession number (0157224).

Limitations

• Key metadata such as row count, file size, specific column names, and license information are unavailable across all sources.
• The dataset's freshness is unclear; one platform shows a last updated date of 2026, while another shows 2016, indicating a potential metadata conflict.
• The description is truncated in multiple sources, suggesting incomplete documentation.
