PACIFICA project data from the MIRAI research vessel includes discrete measurements of dissolved inorganic carbon, alkalinity, pH, and nutrients. The dataset likely contains chemical and physical profiles collected via CTD and bottle sampling in the North Pacific Ocean during November and December 1997. Data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient cycles in the North Pacific based on nitrate, phosphate, and silicate data.
- Studying ocean acidification trends based on pH and carbonate system parameters.
- Correlating physical ocean properties with chemical distributions based on temperature, salinity, and hydrostatic pressure profiles.
Strengths
- Data includes multiple key ocean carbon and nutrient parameters such as dissolved inorganic carbon, alkalinity, and pH.
- Measurements were collected during a dedicated research cruise (MR97-K02) using instruments like CTD and Coulometer.
- Dataset is part of the international PACIFICA synthesis project for the Pacific Ocean.
Limitations
- Last updated 1997-12-04 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
