PACIFICA: Ocean Carbon and Chemistry Profiles from the North Pacific, July 2003

July 2003 data collected from the HOKKO MARU research vessel in the North Pacific Ocean during cruise HK0307. The dataset includes dissolved inorganic carbon, temperature, salinity, nitrate, phosphate, and silicate measurements from discrete water samples and CTD profiles. These data were collected by Tsuneo Ono of the National Research Institute of Fisheries Science as part of the PACIFICA international synthesis project.

Use Cases

• Modeling ocean carbon storage and acidification based on dissolved inorganic carbon measurements.
• Analyzing nutrient distributions and their relationship to water masses based on nitrate, phosphate, and silicate data.
• Studying physical and chemical oceanographic profiles based on concurrent temperature, salinity, and pressure data.
• Calibrating or validating regional biogeochemical models based on high-quality, discrete sample data.

Strengths

• Data covers a specific 11-day period from 2003-07-01 to 2003-07 11, providing a temporal snapshot.
• Includes seven key oceanographic variables: dissolved inorganic carbon, pressure, nitrate+nitrite, phosphate, salinity, silicate, and temperature.
• Data originates from a defined international project (PACIFICA) supported by PICES, suggesting a standardized collection protocol.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Data is from a single, short cruise, limiting temporal and spatial generalizability.
