Six research cruises from January 2005 to May 2006 collected surface underway data in the US South East Coastal Waters and North Atlantic Ocean. The dataset includes measurements of partial pressure of carbon dioxide in water, sea surface temperature, salinity, and barometric pressure. Data were collected by Wei-Jun Cai of the University of Georgia using CO2 gas analyzers and equilibrators as part of the South Atlantic Bight study.
Use Cases
- Modeling air-sea CO2 flux using partial pressure of carbon dioxide in water and barometric pressure measurements.
- Analyzing the relationship between sea surface temperature and carbon dioxide solubility across five cross-shelf transects.
- Studying coastal carbon system variability by correlating sea surface salinity with partial pressure of carbon dioxide.
- Validating satellite-derived sea surface temperature products with in-situ thermosalinography records.
Strengths
- Data collected across six dedicated research cruises over a 17-month period.
- Spatial coverage includes five named cross-shelf transects from coastline to ~500m depth.
- Specific instruments documented, including Carbon dioxide gas analyzer and SeaBird thermosalinograph.
Limitations
- Limited temporal scope to 2005-2006, with no ongoing updates.
- Geographic scope is restricted to the US South East Coastal Waters and specific transects.
- December 2005 cruise had reduced spatial coverage, missing two transects and depths beyond 200m.
