Surface underway and time series coastal observations capture partial pressure of carbon dioxide in air and water, alongside sea surface temperature and salinity. Data was collected aboard the R.V. Gulf Challenger in the North Atlantic Ocean's Gulf of Maine. The National Oceanic and Atmospheric Administration's National Centers for Environmental Information (NOAA NCEI) provides this dataset covering a six-month period from May to November 2018.
Use Cases
- Analyze the relationship between sea surface temperature and partial pressure of carbon dioxide in water to study solubility-driven CO2 uptake.
- Model air-sea CO2 flux using concurrent measurements of atmospheric and aquatic pCO2 alongside barometric pressure.
- Investigate seasonal trends in coastal carbonate chemistry from May to November using time series pCO2 and salinity data.
- Correlate atmospheric conditions, via air temperature and barometric pressure, with surface ocean pCO2 levels.
Strengths
- Data includes six distinct measured variables: air temperature, barometric pressure, atmospheric pCO2, aquatic pCO2, sea surface salinity, and sea surface temperature.
- Time series and underway surface data provides temporal and spatial coverage for a defined coastal region over a six-month period.
- Specific instrumentation is documented, including a carbon dioxide gas analyzer and a shower head chamber equilibrator.
Limitations
- The dataset is temporally limited to a single season (summer/fall) in 2018, preventing analysis of annual cycles.
- Spatial coverage is confined to the Gulf of Maine, limiting geographic generalizability.
- Key quantitative metadata like row count, sampling frequency, and data resolution are unknown.
