CLIVAR P10 2005: Ocean Carbon and Hydrographic Measurements from the Pacific

Chemical and physical oceanographic data collected from the MIRAI research vessel in the Bismarck Sea, North Pacific, and South Pacific from 2005-05-25 to 2005-07-02. The dataset includes 18 measured variables such as dissolved inorganic carbon, alkalinity, pH, CFCs, and nutrients, collected using instruments like CTDs, titrators, and spectrophotometers. Data were gathered by researchers from JAMSTEC and the Meteorological Research Institute as part of the CLIVAR Global Ocean Carbon and Repeat Hydrography Program.

Use Cases

• Modeling ocean carbon storage and transport based on dissolved inorganic carbon and alkalinity measurements.
• Analyzing ocean acidification trends based on pH and carbonate system parameters.
• Studying water mass age and circulation using chlorofluorocarbon (CFC-11, CFC-12, CFC-113) tracer data.
• Investigating marine nutrient cycles based on nitrate, phosphate, and silicate concentrations.

Strengths

• Data includes 18 distinct chemical and physical variables for a multi-parameter analysis.
• Measurements were taken during a dedicated research cruise (49NZ20050525) over a 39-day period in 2005.
• Data collection followed the standardized protocols of the international CLIVAR Repeat Hydrography Program.

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 is from a single cruise in 2005; temporal and spatial coverage is limited.
