Surface underway chemical, meteorological, and physical data collected from the M/V Nuka Arctica ship of opportunity cruises in the North Atlantic Ocean. The dataset includes measurements of carbon dioxide mole fraction, fugacity, sea surface temperature, and barometric pressure. Data were collected by NOAA's National Centers for Environmental Information from January to November 2018.
Use Cases
- Calculate air-sea CO2 flux using fugacity of CO2 in sea water and mole fraction in outside air.
- Analyze seasonal trends in sea surface temperature and partial pressure of carbon dioxide across the North Atlantic.
- Calibrate satellite-derived sea surface temperature products with in-situ equilibrator temperature measurements.
- Study the relationship between barometric pressure and CO2 mole fraction in the equilibrator headspace.
Strengths
- Data collection spans a 10-month period from 2018-01-18 to 2018-11-30.
- Includes multiple directly measured variables like CO2 mole fraction, fugacity, and sea surface temperature.
- Collected via established instruments including a CO2 gas analyzer and shower head chamber equilibrator.
Limitations
- Sample size, row count, and geographic resolution within the North Atlantic are unknown.
- Data is from a single year (2018), limiting analysis of long-term trends.
- Unknown data density and potential gaps during the 10-month collection period.
