NCEI Accession 0173317 contains surface underway chemical, meteorological, and physical data collected during F.G. Walton Smith coastal cruises in 2017. Data include air-sea difference of partial pressure of carbon dioxide (pCO2), atmospheric pCO2, seawater pCO2, barometric pressure, sea surface salinity, and temperature. The data were collected by researchers from the Rosenstiel School of Marine and Atmospheric Science and NOAA's Atlantic Oceanographic and Meteorological Laboratory.
Use Cases
- Calculate air-sea CO2 flux using the air-sea difference of pCO2 and barometric pressure measurements.
- Analyze correlations between seawater pCO2 and concurrent sea surface salinity and temperature data.
- Model coastal carbon cycling by integrating pCO2 in water and pCO2 in atmosphere time-series data.
- Validate satellite-derived sea surface salinity products using in-situ thermosalinograph readings.
Strengths
- Data includes multiple directly measured carbon system variables like pCO2 in water and atmosphere.
- Measurements cover three distinct ocean regions: Gulf of Mexico, North Atlantic Ocean, and Caribbean Sea.
Limitations
- Temporal coverage is limited to a single year (2017), preventing long-term trend analysis.
- Sample size and spatial resolution are unknown, potentially limiting statistical robustness.
Provenance
- Source
- NOAA National Centers for Environmental Information (NCEI), part of the Global Coastal Carbon Data Project.

- Time Range
- 2017
- Freshness
- Data collection concluded in 2017; dataset represents a static snapshot.
