North Pacific Ocean Carbon Chemistry Profiles from Cruise MR97-K02, 1997

Discrete sample and profile data collected from the MIRAI research vessel in the North Pacific Ocean from 1997-11-11 to 1997-12-04. The dataset includes measurements for dissolved inorganic carbon, pH, alkalinity, salinity, temperature, and nutrients like nitrate and phosphate. Data were collected by researchers from JAMSTEC and the Meteorological Research Institute as part of the PACIFICA international synthesis project.

Use Cases

• Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
• Analyzing nutrient cycling relationships based on nitrate, phosphate, and silicate data.
• Calibrating biogeochemical models using concurrent hydrographic data like temperature, salinity, and pressure.
• Studying carbon system parameters for the Pacific Ocean interior as part of the PACIFICA synthesis project.

Strengths

• Data includes 12 key chemical and physical parameters relevant to ocean carbon studies.
• Specific temporal coverage from November 11 to December 4, 1997.
• Data collected as part of a defined international collaborative project (PACIFICA).

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 1997, which may limit temporal generalizability.
