The East China Sea, North Pacific Ocean, and Philippine Sea are covered by this dataset of ocean interior carbon and related parameters collected during a 1997 cruise. It includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, chlorofluorocarbons, and chlorophyll. The data were collected by researchers from the Japan Meteorological Agency and Meteorological Research Institute as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean acidification trends based on dissolved inorganic carbon and pH measurements.
- Analyzing nutrient cycling in marine ecosystems based on nitrate, phosphate, and silicate data.
- Studying historical chlorofluorocarbon (CFC) distributions based on CFC-11 and CFC-12 measurements.
- Investigating phytoplankton biomass based on chlorophyll a and phaeophytin concentrations.
- Calculating carbon system parameters based on alkalinity and dissolved inorganic carbon data.
Strengths
- Data covers a specific month-long cruise from June 23 to July 22, 1997.
- Includes over 20 measured variables related to ocean carbon chemistry and biology.
- Data were collected as part of an international collaborative project (PACIFICA).
Limitations
- Last updated 1997-07-22 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
