Dissolved inorganic carbon, temperature, salinity and other variables collected from discr

Discrete sample and profile data collected from the HOKKO MARU research vessel in the North Pacific Ocean from 2001-01-13 to 2001-01-18. The data include dissolved inorganic carbon, hydrostatic pressure, nitrate+nitrite, phosphate, salinity, silicate, and water temperature, measured using CTD, Coulometer, and bottle instruments. These data were collected by researchers from Hokkaido National Fisheries Institute and the National Research Institute of Fisheries Science as part of the PACIFICA international collaborative project for synthesizing Pacific Ocean interior carbon data.

Use Cases

• Modeling ocean carbon uptake and storage based on dissolved inorganic carbon measurements.
• Analyzing nutrient distributions (nitrate, phosphate, silicate) in the North Pacific Ocean.
• Studying physical oceanographic properties based on concurrent CTD-derived temperature, salinity, and pressure profiles.
• Calibrating and validating regional or global ocean biogeochemical models based on discrete, high-quality profile data.

Strengths

• Data originates from a defined research cruise (HK0101/PACIFICA_49H520010113) with specific collection dates.
• Measurements include multiple key ocean carbon cycle and physical parameters from discrete samples and profiles.
• Data collection is associated with the PACIFICA international synthesis project, suggesting a standardized context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single, short-duration cruise in 2001.
