PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project synthesizing ocean interior carbon data. This dataset contains discrete chemical and physical measurements from the MIRAI research vessel in the North and South Pacific Ocean between November and December 2004. Data were collected by researchers from JAMSTEC using CTD, Coulometer, and bottle instruments.
Use Cases
- Modeling dissolved inorganic carbon transport based on DIC and alkalinity measurements
- Analyzing ocean acidification trends based on pH and alkalinity data
- Studying nutrient distributions in the Pacific Ocean based on nitrate, phosphate, and silicate concentrations
- Investigating water column structure based on CTD-derived temperature, salinity, and pressure profiles
- Calculating ocean carbon budgets based on combined DIC, oxygen, and nutrient data
Strengths
- Data collected during a dedicated international synthesis project (PACIFICA)
- Includes multiple related chemical parameters (DIC, pH, alkalinity, nutrients, oxygen)
- Spatial coverage spans both the North and South Pacific Ocean
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 2004
