Discrete oceanographic measurements include dissolved inorganic carbon, chlorofluorocarbons, dissolved oxygen, nutrients, temperature, and salinity. Data were collected by T. Amaoka of Hokkaido University during the WOCE_P08N cruise aboard the KAIYO-MARU from June to July 1996. This dataset is part of the larger World Ocean Circulation Experiment, which sampled approximately 23,000 stations between 1990 and 1998.
Use Cases
- Modeling dissolved inorganic carbon concentration as a function of potential temperature, salinity, and nitrate levels.
- Analyzing correlations between chlorofluorocarbon-11 (CFC-11), chlorofluorocarbon-12 (CFC-12), and dissolved oxygen to trace water mass age.
- Investigating nutrient cycles by examining silicate, phosphate, and nitrate relationships across hydrostatic pressure gradients.
- Studying ocean thermal structure using water temperature and potential temperature (theta) profiles from CTD casts.
Strengths
- Includes 11 measured variables covering carbon, tracers, nutrients, and physical properties.
- Data collected as part of a standardized global program (WOCE) covering 23,000 stations from 94 cruises.
Limitations
- Limited temporal coverage to a single cruise over 26 days in 1996.
- Geographic scope is restricted to the East China Sea and Philippine Sea.
- Sample size (number of stations or rows) for this specific accession is not provided.
