VOS_Nuka_Arctica_2013: Surface CO2 Fugacity and Temperature

Surface underway data from the vessel NUKA ARCTICA cover a 10-month period from February to December 2013. Measurements include the partial pressure of carbon dioxide in both the atmosphere and seawater, alongside sea surface temperature, collected across the North Atlantic Ocean and adjacent seas. The dataset was collected by researchers from the Bjerknes Centre for Climate Research and the University of Bergen using specialized gas analyzers and equilibrators.

Use Cases

• Calculating air-sea CO2 flux based on partial pressure differentials.
• Monitoring ocean acidification trends using in-situ pCO2 water measurements.
• Correlating sea surface temperature with carbon dioxide fugacity across different marine regions.
• Validating satellite-derived SST and carbon cycle models with ship-based underway data.

Strengths

• Provides continuous, high-frequency surface measurements across a wide geographic area spanning multiple seas.
• Data collection employs specific, named instruments: Carbon dioxide gas analyzer, shower head chamber equilibrator, and thermosalinographs.
• Dataset is associated with a specific research cruise (ID: 26NA20130201) and principal investigators.

Limitations

• Key metadata such as row count, file size, specific column names, and license are not provided by any source.
• Sources conflict on the last updated date, with one listing 2013-12-31 and another 2026-03-05, creating uncertainty about data currency.
• The dataset description is repeated verbatim across platforms, suggesting limited independent annotation or documentation.
