NOAA NCEI Accession 0209721 contains surface underway chemical, meteorological, and physical data from M/V Nuka Arctica cruises. The dataset includes measurements of carbon dioxide mole fraction, fugacity, sea surface temperature, and barometric pressure collected from January to December 2019. Data were gathered using a carbon dioxide gas analyzer and a shower head chamber equilibrator.
Use Cases
- Analyze temporal trends in fugacity of CO2 in sea water at SST across the 2019 cruise period.
- Model the relationship between sea surface temperature and mole fraction of carbon dioxide in the equilibrator headspace.
- Map the spatial distribution of carbon dioxide measurements in dry outside air across the North Atlantic Ocean.
- Correlate barometric pressure in the equilibrator headspace with water temperature in the equilibrator.
Strengths
- Data collection spans nearly a full year, from 2019-01-16 to 2019-12-17.
- Includes multiple co-located variables (CO2, temperature, pressure) for integrated analysis.
Limitations
- The exact number of data rows, columns, and file size are unknown.
- Data is limited to a single vessel's track in the North Atlantic, restricting spatial coverage.
Provenance
