PACIFICA project data collected from the MIRAI research vessel in the Bering Sea and North Pacific Ocean between October and November 2002. These discrete sample and profile observations include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, and nutrient concentrations. The data were collected by Makio Honda and Susumu Honjo of JAMSTEC using CTD, Coulometer, and bottle instruments.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient dynamics in the North Pacific based on nitrate, phosphate, and silicate data
- Studying ocean acidification trends based on pH and carbonate system parameters
- Calibrating biogeochemical models using concurrent physical data like temperature, salinity, and hydrostatic pressure
Strengths
- Data covers a specific research cruise (MR02-K05 Leg 2) with a clear time range (2002-10-11 to 2002-11-06)
- Includes multiple related chemical and physical parameters (12 variables listed) for integrated analysis
- Collected by named principal investigators from a recognized marine science institution (JAMSTEC)
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 2002, limiting temporal scope for long-term trend analysis
