The Philippine Sea contains discrete sample and profile data collected from the SHUMPU MARU vessel between June 28 and July 6, 2000. Kan Kimura of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute collected measurements for dissolved inorganic carbon, pH, alkalinity, nutrients, and chlorofluorocarbons. This dataset was part of the PACIFICA project, an international synthesis effort for Pacific Ocean interior carbon data supported by PICES.
Use Cases
- Modeling ocean acidification based on pH and alkalinity measurements
- Analyzing carbon sequestration potential based on dissolved inorganic carbon (DIC) and chlorofluorocarbon (CFC) data
- Studying nutrient cycles and phytoplankton productivity based on nitrate, phosphate, silicate, and chlorophyll a data
- Calibrating oceanographic models using concurrent physical parameters like salinity, temperature, and hydrostatic pressure
Strengths
- Data includes over 20 distinct chemical, biological, and physical parameters, enabling multi-variable analysis
- Measurements were collected during a specific cruise (PACIFICA_49SU20000628) using standardized instruments (CTD, Coulometer)
- Project affiliation with the international PACIFICA synthesis effort suggests a degree of quality control
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment for large-scale modeling
- Data freshness should be verified; the last metadata update is dated 2026-03-06
