Chemical and physical oceanographic data collected from the KAIYO-MARU vessel in the North Pacific Ocean and Philippine Sea during June-July 1996. The dataset includes measurements of dissolved inorganic carbon, alkalinity, pH, nutrients, and temperature, collected using CTD and bottle instruments as part of the World Ocean Circulation Experiment (WOCE). The data were collected by Noriya Yoshioka of the Japan Marine Science and Technology Center.
Use Cases
- Modeling ocean carbon uptake and storage based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing nutrient distributions and ocean biogeochemistry based on nitrate, phosphate, and silicate data.
- Studying ocean circulation and water mass properties using potential temperature and salinity profiles.
- Calibrating or validating historical climate models using the 1996 time-stamped ocean chemistry observations.
- Investigating tracer distributions and ocean mixing using helium and tritium isotope data.
Strengths
- Data is part of the World Ocean Circulation Experiment (WOCE), a major international climate research program.
- Includes multiple core ocean chemistry variables (e.g., DIC, alkalinity, nutrients) measured simultaneously.
- Covers a specific research cruise (WOCE_P08S) with a clear temporal range from 1996-06-17 to 1996-07-02.
Limitations
- Last updated 1996-07-02 00:00:00; freshness should be verified.
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file size are unknown, which may limit suitability assessment.
