NUKA ARCTICA 2010: Surface Ocean CO2 and Temperature Measurements

Surface underway data from the NUKA ARCTICA vessel covers the Davis Strait, Labrador Sea, North Atlantic Ocean, North Sea, and Baltic Sea passages from January to December 2010. The dataset includes measurements of the partial pressure (fugacity) of carbon dioxide in both the atmosphere and surface water, alongside sea surface temperature. Data were collected using a Carbon dioxide (CO2) gas analyzer as part of the VOS_Nuka_Arctica_2010 project.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure measurements in water and atmosphere.
• Analyzing seasonal variability of surface ocean carbon parameters along a shipping route.
• Validating regional ocean carbon models with in-situ underway observations.
• Investigating correlations between sea surface temperature and CO2 fugacity in subpolar waters.

Strengths

• Data collection spans a full annual cycle from 2010-01-08 to 2010-12-15.
• Specific instrument (Carbon dioxide gas analyzer) and principal investigators are documented.
• Dataset is curated and assigned a formal NCEI accession number (0157315) and cruise ID (26NA20100108).

Limitations

• Column names and exact row count are not provided in the available metadata.
• Conflicting 'last updated' dates (2010-12-15 vs. 2026-03-06) suggest potential metadata inconsistency across platforms.
• Data granularity (e.g., temporal resolution of underway measurements) is not specified.
