Surface underway and time series data collected from the R.V Gulf Challenger in the North Atlantic Ocean's Gulf of Maine. The dataset includes measurements of air temperature, barometric pressure, partial pressure of carbon dioxide in air and water, sea surface salinity, and sea surface temperature. Data were collected by NOAA's National Centers for Environmental Information from February to October 2019.
Use Cases
- Analyze the relationship between sea surface temperature and pCO2 in water to study seasonal carbon dynamics.
- Model air-sea CO2 flux using concurrent measurements of atmospheric pCO2 and sea surface pCO2.
- Correlate sea surface salinity with pCO2 in water to understand freshwater influence on coastal carbon chemistry.
- Investigate diurnal or seasonal cycles using the time series of air temperature and barometric pressure.
Strengths
- Data collection spans an 8-month period from February to October 2019.
- Includes concurrent measurements of atmospheric and aquatic carbon dioxide partial pressure.
Limitations
- Limited to a single year and specific geographic region (Gulf of Maine).
- Unknown sample size and temporal resolution of the time series.
