Discrete sample and profile observations of dissolved inorganic carbon, pH, temperature, salinity, and related variables collected from the MIRAI research vessel in the North and South Pacific Ocean between December 27, 2000 and February 8, 2001. The data were collected by Takeshi Kawano of JAMSTEC and Masao Ishii of the Meteorological Research Institute using CTD, Coulometer, and bottle instruments. This dataset is part of the PACIFICA project, an international synthesis effort for ocean interior carbon data in the Pacific Ocean.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing biogeochemical relationships based on nitrate, phosphate, silicate, and ammonium concentrations.
- Studying phytoplankton biomass distribution based on chlorophyll a and phaeopigment data.
- Investigating water column structure and properties based on CTD-derived salinity, temperature, and hydrostatic pressure profiles.
Strengths
- Includes 17 measured variables covering key ocean carbon and chemistry parameters.
- Data collected during a specific cruise (MR00-K08/PACIFICA_49NZ20001227) over a defined period (2000-12-27 to 2001-02-08).
- Project is part of an international collaborative synthesis effort (PACIFICA) supported by PICES.
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 geographic and temporal bias inherent to a single research cruise.
