From January 7 to February 16, 2002, this dataset contains discrete sample and profile observations of dissolved inorganic carbon, nutrients, chlorophyll, and physical oceanographic variables collected aboard the MIRAI research vessel in the North and South Pacific Oceans. The data were collected by researchers from JAMSTEC and the Meteorological Research Institute using CTD, Coulometer, and bottle instruments. It was compiled as part of the international PACIFICA project for synthesizing ocean interior carbon data in the Pacific Ocean.
Use Cases
- Modeling ocean acidification based on dissolved inorganic carbon (DIC) and pH measurements.
- Analyzing nutrient cycling based on ammonium, nitrate, nitrite, phosphate, and silicate data.
- Studying phytoplankton biomass distribution based on chlorophyll a and phaeopigment concentrations.
- Correlating physical ocean properties with chemical parameters based on temperature, salinity, and hydrostatic pressure.
- Validating ocean carbon models for the Pacific interior based on the PACIFICA project synthesis data.
Strengths
- Includes multiple related parameter types: biological, chemical, optical, and physical oceanographic data.
- Data collected over a specific cruise period from January 7 to February 16, 2002.
- Associated with a defined international collaborative project (PACIFICA) and specific cruise IDs (MR02-K01, PACIFICA_49NZ20020107).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect temporal bias inherent to a single cruise in 2002.
