PACIFICA was an international project synthesizing ocean interior carbon data. This dataset includes discrete measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, and physical parameters collected via CTD and bottle sampling during a 1998 cruise. The data were collected by researchers from the Japan Agency for Marine-Earth Science and Technology (Jamstec) aboard the MIRAI.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Analyzing nutrient cycling in the North Pacific based on ammonium, nitrate, phosphate, and silicate data.
- Studying the relationship between physical oceanography and carbon chemistry based on concurrent salinity, temperature, and hydrostatic pressure profiles.
- Calibrating biogeochemical models using discrete sample data for alkalinity and dissolved oxygen.
Strengths
- Includes 12 key chemical and physical variables relevant to ocean carbon research.
- Data collected during a specific research cruise (MR98-K01) over a defined period from 1998-10-30 to 1998-12-15.
- Project was supported by an international scientific organization (PICES, Section of Carbon and Climate).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Last updated 1998-12-15; freshness should be verified for contemporary applications.
- Row count is unknown, which may limit suitability assessment for large-scale modeling.
