PACIFICA project data includes 22 chemical, biological, and physical variables like dissolved inorganic carbon, pH, and chlorophyll A, collected from the SHUMPU MARU research vessel. Measurements were taken in the Philippine Sea over a nine-day period in October 1998 using CTD, Coulometer, and bottle instruments. Koji Hayashi of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute led the data collection for this international ocean carbon synthesis effort.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyzing nutrient cycles and primary productivity based on nitrate, phosphate, silicate, and chlorophyll A data.
- Studying water mass properties and circulation using temperature, salinity, and potential temperature (theta) profiles.
- Investigating anthropogenic tracer distribution based on chlorofluorocarbon (CFC-11, CFC-12) concentrations.
Strengths
- Includes 22 distinct chemical, biological, and physical variables for a multi-parameter analysis.
- Data collection is precisely dated from 1998-10-07 to 1998-10-15 in the Philippine Sea.
- Originates from a recognized international collaborative project (PACIFICA) supported by PICES.
Limitations
- Last updated 1998-10-15 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
