PACIFICA_49RY19970623 includes biological, chemical, and physical profile data collected from the RYOFU MARU in the East China Sea, North Pacific Ocean, and Philippine Sea from 1997-06-23 to 1997-07-22. Naoshi Kubo of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute collected these data using CTD and bottle instruments. The dataset contains measurements for dissolved inorganic carbon, pH, alkalinity, nutrients, chlorophyll, and chlorofluorocarbons.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyzing nutrient cycling and phytoplankton productivity based on nitrate, phosphate, and chlorophyll a data.
- Studying historical chlorofluorocarbon distributions based on CFC-11 and CFC-12 measurements.
- Investigating water column structure and oceanographic properties based on CTD-derived temperature, salinity, and pressure profiles.
Strengths
- Data covers a specific cruise spanning one month across three distinct ocean regions.
- Includes over 20 measured variables related to ocean carbon, nutrients, and physical properties.
- Data were collected as part of the international PACIFICA synthesis project supported by PICES.
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 1997.
