PACIFICA (PACIFic ocean Interior CArbon) collected discrete sample and profile data from the WAKATAKA MARU in the North Pacific Ocean from 1996-05-16 to 1996-05-25. The data include dissolved inorganic carbon, alkalinity, pH, salinity, temperature, nutrients, and chlorophyll A. These measurements were taken by researchers from JAMSTEC, NRIFS, and Tokyo University using CTD, Coulometer, and bottle instruments.
Use Cases
- Modeling ocean acidification impacts based on pH and dissolved inorganic carbon measurements.
- Studying nutrient cycling in marine ecosystems based on nitrate, nitrite, phosphate, and silicate concentrations.
- Analyzing relationships between physical and chemical ocean properties based on concurrent temperature, salinity, and alkalinity data.
- Investigating phytoplankton biomass based on chlorophyll A measurements.
Strengths
- Data covers a specific 10-day cruise in May 1996, providing a focused temporal snapshot.
- Includes multiple related chemical and physical parameters measured concurrently.
- Project was an international collaboration supported by PICES, suggesting coordinated data collection.
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 bias inherent to a single cruise track in the North Pacific Ocean.
