North Pacific Ocean data includes dissolved inorganic carbon, temperature, salinity, and nutrient concentrations from discrete water samples and CTD profiles. The dataset was collected aboard the HOKKO MARU from May 9 to 16, 1996 by Shuichi Watanabe of Hokkaido University as part of the PACIFICA project. It contains measurements for seven key oceanographic variables.
Use Cases
- Analyze correlations between dissolved_inorganic_carbon and water_temperature to study carbon solubility.
- Model vertical profiles of nitrate_nitrite_content and phosphate using hydrostatic_pressure as the depth proxy.
- Assess silicate distribution relative to salinity and temperature for water mass characterization.
- Calibrate ocean carbon models with in-situ dissolved_inorganic_carbon measurements from a specific cruise.
Strengths
- Includes seven key ocean interior variables: dissolved inorganic carbon, temperature, salinity, and four nutrients.
- Data collected during a dedicated research cruise (HK9605) ensuring methodological consistency.
- Part of the international PACIFICA data synthesis project for the Pacific Ocean.
Limitations
- Temporal coverage is limited to an 8-day period in May 1996.
- Geographic scope is confined to the specific cruise track of the HOKKO MARU in the North Pacific Ocean.
- Sample size and row count are unknown, potentially limiting statistical power.
