PACIFICA_49TA20011005 includes discrete sample and profile data collected from the TANKAI-MARU in the North Pacific Ocean from 2001-10-05 to 2001-10-10. Tsuneo Ono of the National Research Institute of Fisheries Science collected dissolved inorganic carbon, salinity, temperature, nitrate, phosphate, and silicate using CTD and Coulometer instruments. The PACIFICA project was an international synthesis effort for ocean interior carbon data in the Pacific, supported by PICES.
Use Cases
- Modeling dissolved inorganic carbon dynamics in the North Pacific based on DIC measurements.
- Analyzing relationships between water temperature and nutrient concentrations (nitrate, phosphate, silicate) from profile data.
- Studying hydrostatic pressure and salinity profiles for oceanographic research.
- Calibrating or validating ocean carbon cycle models using discrete sample chemistry data.
Strengths
- Data collected over a specific 5-day cruise in October 2001.
- Includes multiple key ocean chemistry parameters: DIC, nutrients, salinity, and temperature.
- Part of the international PACIFICA project for data synthesis.
Limitations
- Row count and dataset size are unknown.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to a single cruise in the North Pacific.
