East China Sea, North Pacific Ocean, Philippine Sea, and South Pacific Ocean surface observations collected from the KEIFU MARU vessel between 2001-01-20 and 2011-03-22. The data include barometric pressure, carbon dioxide levels in air, partial pressure of carbon dioxide, salinity, and sea surface temperature. Akira Nakadate and Shu Saito of the Japan Meteorological Agency collected these data as part of the VOS R/V Keifu Maru Lines data set.
Use Cases
- Modeling ocean carbon sink dynamics based on partial pressure of carbon dioxide measurements.
- Analyzing air-sea carbon dioxide flux based on surface water and atmospheric CO2 data.
- Studying regional variability in marine carbon chemistry based on data from the East China Sea and North Pacific Ocean.
- Investigating correlations between sea surface temperature and carbon dioxide solubility based on concurrent measurements.
Strengths
- Data collection spans over a decade, from 2001-01-20 to 2011-03-22.
- Observations cover multiple ocean basins: East China Sea, North Pacific Ocean, Philippine Sea, and South Pacific Ocean.
- Includes multiple related variables: barometric pressure, carbon dioxide in air and water, salinity, and sea surface temperature.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
