North Atlantic Ocean Surface Carbon Dioxide and Temperature Measurements from 2020

North Atlantic Ocean surface underway data from January to April 2020 includes chemical, meteorological, and physical variables. The dataset contains measurements of carbon dioxide mole fractions, sea surface temperature, and barometric pressure collected during M/V Nuka Arctica ship of opportunity cruises. Data were collected by NOAA NCEI using a carbon dioxide gas analyzer and a shower head chamber equilibrator.

Use Cases

• Calculate sea water CO2 fugacity from equilibrator temperature and barometric pressure measurements.
• Analyze the relationship between sea surface temperature and mole fraction of CO2 in dry outside air.
• Model temporal trends in equilibrator headspace CO2 concentrations during the 2020 cruise period.
• Correlate barometric pressure in the equilibrator headspace with meteorological conditions.

Strengths

• Data covers a 3.5-month time range from 2020-01-01 to 2020-04-15.
• Includes multiple related chemical and physical variables for integrated analysis.
• Collected via established ship of opportunity program using specific instruments like a CO2 gas analyzer.

Limitations

• Sample size, row count, and specific column details are unknown.
• Geographic coverage is limited to the specific cruise tracks of the M/V Nuka Arctica in the North Atlantic.
• Data is from a single year and season, limiting long-term trend analysis.
