North Pacific Ocean chemical and physical data collected from the HOKKO MARU vessel between 2003-06-09 and 2003-06-17. The dataset includes dissolved inorganic carbon, nitrate, phosphate, silicate, salinity, and temperature measurements from discrete samples and CTD profiles. Tsuneo Ono of the National Research Institute of Fisheries Science collected these data as part of the PACIFICA international ocean carbon synthesis project.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon measurements
- Analyzing nutrient distributions based on nitrate, phosphate, and silicate concentrations
- Studying ocean temperature and salinity profiles from CTD data
- Investigating biogeochemical relationships in the North Pacific Ocean interior
Strengths
- Data collected during a dedicated research cruise (HK0306/PACIFICA_49H520030609)
- Includes multiple key ocean chemistry variables (DIC, nitrate, phosphate, silicate, salinity, temperature)
- Part of an international collaborative synthesis project (PACIFICA) supported by PICES
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 geographic bias inherent to a single cruise in the North Pacific Ocean
