PACIFICA: Ocean Carbon and Chemistry Profiles from the North Pacific, 2007

PACIFICA_49H520070508 data includes dissolved inorganic carbon, temperature, salinity, and nutrient measurements collected from the HOKKO MARU research vessel in the North Pacific Ocean from May 8 to 14, 2007. Tsuneo Ono of the National Research Institute of Fisheries Science collected the data using CTD, Coulometer, and bottle instruments during cruise HK0705. The dataset was part of the PACIFICA international project for synthesizing Pacific Ocean interior carbon data, supported by PICES.

Use Cases

• Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon measurements.
• Analyzing relationships between water temperature, salinity, and nutrient concentrations from profile data.
• Studying spatial distributions of nitrate, phosphate, and silicate in the North Pacific Ocean.

Strengths

• Data collected during a dedicated research cruise (HK0705) with specific instruments (CTD, Coulometer).
• Part of the international PACIFICA project for data synthesis, suggesting standardized collection.
• Includes multiple related chemical and physical variables (DIC, nutrients, temperature, salinity).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Temporal coverage is limited to a single week in May 2007.
