PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for data synthesis of ocean interior carbon and related parameters. This dataset includes discrete sample and profile observations collected from the KEIFU MARU in the North Pacific Ocean and Philippine Sea from 2002-10-31 to 2002-11-11. The data were collected by Naoyuki Ishikawa of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute using CTD, Coulometer, and bottle instruments.
Use Cases
- Modeling ocean carbon sequestration based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient cycles based on nitrate, phosphate, and silicate concentrations
- Studying ocean acidification trends based on pH and dissolved inorganic carbon data
- Investigating chlorofluorocarbon (CFC) tracer distribution for ocean circulation studies
- Calibrating biogeochemical models using profile data for temperature, salinity, and dissolved oxygen
Strengths
- Data covers a specific cruise (PACIFICA_49FA20021031) with a defined temporal range from 2002-10-31 to 2002-11-11
- Includes a wide range of chemical, biological, and physical parameters such as alkalinity, chlorophyll a, CFCs, and nutrients
- Project was supported by the North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC)
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 cruise in 2002
