Surface underway measurements of carbon dioxide partial pressure and related variables collected aboard the R/V ROGER REVELLE across the Indian and Pacific Oceans from February to September 2016. The data include air-sea difference of carbon dioxide, barometric pressure, salinity, and sea surface temperature, collected using a Carbon dioxide (CO2) gas analyzer. Researchers Rik Wanninkhof, Denis Pierrot, and Kevin Sullivan of NOAA's Atlantic Oceanographic and Meteorological Laboratory led the collection effort across seven distinct cruise legs.
Use Cases
- Modeling ocean carbon sink dynamics based on partial pressure of carbon dioxide measurements.
- Analyzing air-sea gas exchange rates based on the air-sea difference in carbon dioxide fugacity.
- Studying regional variability in sea surface chemistry based on salinity and temperature data across multiple ocean basins.
- Validating satellite-derived sea surface temperature and salinity products based on in-situ underway observations.
Strengths
- Data covers a wide geographic area spanning the Andaman Sea, Bay of Bengal, Indian Ocean, and North and South Pacific Ocean.
- Collection occurred over a 7-month period in 2016 across seven specific cruise legs, providing temporal granularity.
- Variables are directly relevant for carbon cycle studies, including the key metric of air-sea difference in carbon dioxide partial pressure.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
