Nuka Arctica SOOP: North Atlantic Ocean CO2 Fugacity and SST

Surface underway measurements from the M/V Nuka Arctica ship of opportunity cruises in the North Atlantic Ocean from December 29, 2016 to December 27, 2017. The dataset includes mole fraction of carbon dioxide in equilibrator headspace and dry air, barometric pressure, water temperature, sea surface temperature, and fugacity of CO2 in seawater. Data were collected using a CO2 gas analyzer and shower head chamber equilibrator by researchers from the University of Bergen's Bjerknes Centre for Climate Research.

Use Cases

• Calculating air-sea CO2 flux based on fugacity of CO2 in seawater and mole fraction in air
• Monitoring temporal variability of surface ocean carbon dioxide based on underway measurements
• Correlating sea surface temperature with carbon dioxide partial pressure
• Validating regional carbon cycle models using in-situ CO2 and meteorological data

Strengths

• Data covers a specific, continuous time range from 2016-12-29 to 2017-12-27
• Includes direct measurements from specialized instruments: CO2 gas analyzer and shower head chamber equilibrator
• Collected by named researchers from a recognized climate research institution (University of Bergen, Bjerknes Centre)

Limitations

• Column names and exact data structure are unknown across all platforms
• Row count, dataset size, and license information are not provided
• Last updated date conflicts between sources (2026-03-05 vs 2017-12-27)
