From August 19 to 27, 1998, discrete water samples and profiles were collected from the SHUMPU MARU research vessel in the Philippine Sea. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, nutrients, and chlorofluorocarbons, collected by researchers from the Japan Meteorological Agency and Meteorological Research Institute as part of the PACIFICA project.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
- Studying nutrient cycling in the ocean interior based on nitrate, phosphate, and silicate data.
- Analyzing historical water mass properties based on temperature, salinity, and potential temperature (theta).
- Investigating anthropogenic tracer distribution based on chlorofluorocarbon-11 and -12 measurements.
Strengths
- Includes over 20 distinct chemical, biological, and physical parameters, such as dissolved inorganic carbon, alkalinity, and chlorophyll a.
- Data were collected during a dedicated research cruise (PACIFICA_49SU19980819) as part of an international synthesis project.
- Specific collection instruments are named, including CTD and Coulometer for DIC measurement.
Limitations
- Last updated 1998-08-27 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
