North Pacific Ocean Carbon Chemistry Profiles from OSHORO MARU, June 2002

PACIFICA project data collected from the North Pacific Ocean between June 6 and 19, 2002, during cruise OS02-01. The dataset includes dissolved inorganic carbon, alkalinity, pH, salinity, temperature, and nutrient measurements from discrete samples and CTD profiles. Yutaka W. Watanabe of Hokkaido University collected the data as part of an international synthesis effort supported by PICES.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing nutrient cycling in the North Pacific based on nitrate, phosphate, and silicate data.
• Calibrating ocean carbon models based on hydrographic profiles of temperature, salinity, and pressure.
• Studying carbonate system dynamics based on paired alkalinity and dissolved inorganic carbon observations.

Strengths

• Data covers a specific 14-day research cruise in June 2002, providing a temporal snapshot.
• Includes 12 key oceanographic variables, including carbonate system and nutrient parameters.
• Data is part of the PACIFICA international synthesis project for the Pacific Ocean.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single cruise in 2002; temporal and spatial coverage is limited.
