From June to December 2011, surface underway measurements of carbon dioxide partial pressure, salinity, and sea temperature were collected from the WAKATAKA MARU across the North Atlantic, North Pacific, and South Atlantic Oceans. The data were collected by researchers from the National Research Institute of Fisheries Science and Tohoku Regional Fisheries Research Laboratory using carbon dioxide gas analyzers and equilibrators. This dataset is associated with the VOS_Wakataka_Maru_2011 and VOS_Wakataka_Maru_WK1112 research cruises.
Use Cases
- Modeling air-sea carbon dioxide flux based on partial pressure measurements.
- Analyzing correlations between sea surface temperature and carbon dioxide fugacity.
- Studying regional variability in surface ocean carbon chemistry across major ocean basins.
- Validating satellite-derived sea surface salinity products with in-situ measurements.
Strengths
- Data collection spans three major ocean basins over a six-month period in 2011.
- Includes key variables for carbon cycle studies: carbon dioxide partial pressure, salinity, sea temperature, and barometric pressure.
- Instruments used are specified, including Carbon dioxide (CO2) gas analyzer and Micro-porous membrane equilibrator.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 2011-12-06; freshness should be verified for contemporary climate studies.
- Row count is unknown, which may limit suitability assessment for large-scale statistical modeling.
