From 2019-01-08 to 2019-12-07, surface underway data was collected by the National Oceanic and Atmospheric Administration aboard the R/V Keifu Maru II in the Pacific Ocean, East China Sea, and Sea of Japan. The data likely includes measurements of barometric pressure, partial pressure of carbon dioxide in the atmosphere and water, sea surface salinity, and sea surface temperature. Instruments used include a carbon dioxide gas analyzer and a shower head chamber equilibrator.
Use Cases
- Modeling ocean carbon uptake based on partial pressure of carbon dioxide - water measurements
- Analyzing sea surface temperature and salinity correlations with atmospheric CO2 levels
- Studying regional carbon dioxide variability in the East China Sea and Sea of Japan
- Calibrating autonomous CO2 measurement systems using data from shower head chamber equilibrators
Strengths
- Data collection spans nearly a full year, from January to December 2019
- Includes simultaneous measurements of atmospheric and aquatic partial pressure of carbon dioxide
- Geographic coverage includes the Pacific Ocean, East China Sea, and Sea of Japan
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic/temporal bias inherent to the specific vessel's cruise track
