North Pacific Ocean chemical and physical profile data collected aboard the TANKAI-MARU from April 18-20, 1998. The dataset includes dissolved inorganic carbon, salinity, temperature, nitrate, phosphate, and silicate measurements. Data were gathered by Tsuneo Ono of the National Research Institute of Fisheries Science as part of the international PACIFICA project.
Use Cases
- Analyze dissolved inorganic carbon concentrations against salinity and water temperature to study carbon sequestration.
- Model relationships between nitrate+nitrite content, phosphate, and silicate levels using profile data.
- Correlate hydrostatic pressure readings with chemical measurements to understand vertical ocean gradients.
- Use the time-series from the 3-day cruise to examine short-term variability in North Pacific carbon parameters.
Strengths
- Includes 7 key oceanographic variables: dissolved inorganic carbon, salinity, temperature, nitrate, phosphate, silicate, and pressure.
- Data collected during a dedicated scientific cruise (PACIFICA_49TA19980418) using CTD and Coulometer instruments.
Limitations
- Extremely limited temporal coverage from a single 3-day cruise in 1998.
- Geographic scope is restricted to the specific cruise track of the TANKAI-MARU in the North Pacific.
- Sample size and row count are unknown, potentially representing a small snapshot.
Provenance
