PACIFICA project data includes dissolved inorganic carbon, alkalinity, chlorofluorocarbons, and nutrients collected from the RYOFU MARU research vessel. The dataset covers a cruise from September to November 1997 across the North and South Pacific Ocean. It was collected by researchers from the Japan Meteorological Agency and Meteorological Research Institute.
Use Cases
- Model ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyze historical chlorofluorocarbon (CFC-11, CFC-12) distributions as ocean tracers.
- Study marine nutrient cycles based on nitrate, phosphate, and silicate concentrations.
- Assess biological productivity indicators based on chlorophyll a and phaeopigment data.
- Calculate ocean density and stratification based on salinity, temperature, and sigma-theta profiles.
Strengths
- Includes over 20 distinct chemical, biological, and physical parameters for ocean interior analysis.
- Data originates from a specific research cruise (PACIFICA_49RY19970912) providing a coherent snapshot.
- Supported by the international PACIFICA project and the North Pacific Marine Science Organization (PICES).
Limitations
- Last updated 1997-11-07 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.
