2020 data from January to November includes surface underway and time series coastal measurements of partial pressure of carbon dioxide, temperature, and salinity in the North Atlantic Ocean's Gulf of Maine. The dataset was collected during R/V Gulf Challenger cruises by NOAA's National Centers for Environmental Information. It contains chemical, meteorological, and physical variables such as air temperature, barometric pressure, and sea surface conditions.
Use Cases
- Calculate air-sea CO2 flux using pCO2 in atmosphere and pCO2 in water columns alongside sea surface temperature.
- Analyze seasonal trends in ocean acidification drivers from pCO2 in water and sea surface salinity time series.
- Model relationships between meteorological conditions like air temperature and barometric pressure and surface ocean carbon concentrations.
- Validate satellite-derived sea surface temperature and salinity products with in-situ measurements from the cruises.
Strengths
- Temporal coverage spans 10 months from 2020-01-04 to 2020-11-08.
- Includes directly measured carbon dioxide partial pressure in both air and water.
Limitations
- Sample size and spatial resolution are unknown from the provided metadata.
- Limited to a single year and region (Gulf of Maine), restricting long-term or global analysis.
