North Pacific Ocean Carbon Chemistry Profiles from Cruise MR00-K01, 2000

PACIFICA_49NZ20000105 includes chemical and physical profile data collected from the MIRAI research vessel in the North Pacific Ocean from 2000-01-05 to 2000-02-06. The data contain measurements for dissolved inorganic carbon, alkalinity, pH, nutrients, and physical variables like temperature and salinity. These 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 dissolved inorganic carbon and pH measurements.
• Analyzing nutrient cycling relationships based on nitrate, phosphate, and silicate data.
• Studying water mass properties and mixing based on concurrent temperature, salinity, and oxygen profiles.
• Calibrating biogeochemical models with in-situ alkalinity and carbon system parameter data.

Strengths

• Data includes multiple key carbon system parameters (DIC, alkalinity, pH) measured concurrently.
• Measurements are part of the PACIFICA international synthesis project for the Pacific Ocean.
• Data collection period is precisely defined from 2000-01-05 to 2000-02-06.

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 2000, limiting temporal and spatial generalizability.
