Ocean Carbon and Chemistry Profiles from the Philippine Sea, October 2000

Discrete oceanographic measurements collected from the SHUMPU MARU research vessel in the Philippine Sea between October 11 and 19, 2000. The data include dissolved inorganic carbon, pH, alkalinity, nutrients, chlorophyll, and related physical parameters like temperature and salinity. These observations were made by researchers from the Japan Meteorological Agency and the Meteorological Research Institute as part of the international PACIFICA carbon synthesis project.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
• Studying marine nutrient cycles based on nitrate, phosphate, and silicate concentrations.
• Analyzing water mass properties and ocean circulation based on CTD-derived temperature, salinity, and pressure profiles.
• Investigating phytoplankton biomass distribution based on chlorophyll a and phaeopigment data.

Strengths

• Includes over 20 measured variables relevant to ocean carbon and biogeochemistry.
• Data collected during a defined research cruise (PACIFICA_49SU20001011) over a 9-day period in October 2000.
• Part of the international PACIFICA project, suggesting standardized collection protocols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single, short cruise, limiting temporal and spatial generalizability.
