From July 5 to July 14, 2002, this dataset contains chemical and physical profile data collected from the TANKAI-MARU vessel in the North Pacific Ocean. It includes measurements of dissolved inorganic carbon, nitrate, phosphate, silicate, salinity, and water temperature, gathered using CTD and bottle instruments. The data were collected by Tsuneo Ono of the National Research Institute of Fisheries Science as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon measurements
- Analyzing nutrient distributions in the North Pacific based on nitrate, phosphate, and silicate concentrations
- Studying the relationship between water temperature and salinity profiles from CTD data
- Investigating ocean acidification trends based on carbonate system parameters
Strengths
- Data covers a specific 10-day cruise period from July 5 to July 14, 2002
- Includes multiple key oceanographic parameters: dissolved inorganic carbon, nitrate, phosphate, silicate, salinity, and temperature
- Data collected as part of an international collaborative 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
