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

From 2000-05-07 to 2000-05-15, 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, nutrients, chlorophyll, and chlorofluorocarbons, collected using CTD, Coulometer, and bottle instruments. These measurements were contributed by researchers from the Japan Meteorological Agency and the Meteorological Research Institute as part of the international PACIFICA data synthesis project.

Use Cases

• Modeling ocean acidification dynamics based on pH and alkalinity measurements.
• Studying marine biological productivity based on chlorophyll a and nutrient (nitrate, phosphate) concentrations.
• Tracing water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12) data.
• Investigating the oceanic carbon cycle based on dissolved inorganic and organic carbon measurements.

Strengths

• Data covers a specific 9-day cruise in May 2000, providing a temporal snapshot.
• Includes over 20 measured variables related to carbon, nutrients, and physical oceanography.
• Collected as part of the international PACIFICA project for data synthesis and quality assurance.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic and temporal bias inherent to a single cruise in the Philippine Sea.
