NCEI 0165355: CO2 Fugacity from Shipboard Measurements in the North Atlantic

NCEI Accession 0165355 contains surface underway data collected aboard the M/V Nuka Arctica in the North Atlantic Ocean from February to December 2016. The dataset includes measurements of carbon dioxide fugacity in seawater, mole fraction of CO2 in air and equilibrator headspace, sea surface temperature, and barometric pressure. Data were collected by researchers from the University of Bergen's Bjerknes Centre for Climate Research using a carbon dioxide gas analyzer and shower head chamber equilibrator.

Use Cases

• Calculating air-sea CO2 flux based on fugacity measurements and meteorological data.
• Monitoring seasonal variability of surface ocean carbon parameters along shipping routes.
• Validating and calibrating satellite-derived estimates of sea surface pCO2.
• Assessing ocean acidification trends in the North Atlantic region.

Strengths

• Data collection covers a nearly year-long time range from 2016-02-06 to 2016-12-27.
• Specific instrumentation is documented: carbon dioxide gas analyzer and shower head chamber equilibrator.
• Dataset is hosted by NOAA NCEI, a trusted national data repository.

Limitations

• Column names and exact data structure are not provided in the available metadata.
• Exact row count and file size are unknown, limiting assessment of dataset scale.
• Conflicting 'last updated' dates exist between platforms (2016-12-27 and 2026-03-05).
