PACIFICA_49RY19980703 includes 22 variables such as dissolved inorganic carbon, alkalinity, pH, and chlorofluorocarbons collected from the RYOFU MARU during July 1998. The data were gathered using CTD and bottle instruments across the North Pacific Ocean, Philippine Sea, and South Pacific Ocean. It was collected by researchers from the Japan Meteorological Agency and Meteorological Research Institute as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing historical chlorofluorocarbon (CFC-11, CFC-12) distributions as ocean tracers.
- Studying nutrient cycles and marine productivity based on nitrate, phosphate, and silicate data.
- Investigating ocean acidification trends based on pH and carbonate system parameters.
- Calibrating biogeochemical models using concurrent measurements of temperature, salinity, and dissolved oxygen.
Strengths
- Includes 22 distinct chemical, biological, and physical parameters for a multi-faceted analysis.
- Data collected over a focused time range (1998-07-03 to 1998-07-31) during a dedicated research cruise.
- Spatial coverage spans three major ocean basins: North Pacific Ocean, Philippine Sea, and South Pacific Ocean.
Limitations
- Last updated 1998-07-31; freshness should be verified for contemporary applications.
- Row count and column-level documentation are unknown, which may limit suitability assessment.
- Data may reflect geographic and temporal bias inherent to a single cruise in July 1998.
