PACIFICA project data collected from the RYOFU MARU vessel in the North Pacific Ocean during June 1998 includes dissolved inorganic carbon, alkalinity, pH, nutrients, and chlorofluorocarbons. Akira Nakadate of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute gathered these discrete sample and profile measurements using CTD and bottle instruments. The dataset supports international synthesis of ocean interior carbon parameters for climate studies.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient cycling in marine ecosystems based on nitrate, phosphate, and silicate concentrations
- Studying chlorofluorocarbon distribution as ocean tracers based on CFC-11 and CFC-12 data
- Calculating carbon sequestration potential based on alkalinity and dissolved organic carbon
- Correlating biological productivity with environmental factors based on chlorophyll a and phaeophytin levels
Strengths
- Includes 22 distinct chemical, biological, and physical parameters relevant to carbon cycling
- Data originates from a specific research cruise (PACIFICA_49RY19980609) with known principal investigators
- Supports an international collaborative project (PACIFICA) endorsed by PICES S-CC
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect temporal bias inherent to a single cruise in June-July 1998
