PACIFICA_49RY20040704 includes biological, chemical, and physical data collected from the Ryofu Maru II research vessel in the North Pacific Ocean, Philippine Sea, and South Pacific Ocean from July 4 to July 21, 2004. Kazuhiro Nemoto of the Japan Meteorological Agency and Masao Ishii of the Meteorological Research Institute collected these data using CTD, Coulometer, and bottle instruments. The dataset contains measurements for dissolved inorganic carbon, pH, alkalinity, nutrients, chlorofluorocarbons, and other oceanographic parameters.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements
- Analyzing nutrient cycling in the Pacific Ocean based on nitrate, phosphate, and silicate concentrations
- Studying chlorofluorocarbon distribution as ocean tracers based on CFC-11 and CFC-12 data
- Investigating marine primary productivity based on chlorophyll a and phaeophytin levels
- Calculating carbon isotope ratios in seawater based on delta carbon-13 measurements
Strengths
- Data covers a specific 18-day cruise in July 2004, providing a temporally focused snapshot
- Includes over 20 distinct chemical, biological, and physical parameters, suggesting a multi-variable profile
- Data collected by named researchers from the Japan Meteorological Agency and Meteorological Research Institute
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 bias inherent to the specific cruise track
