From August 7 to October 3, 1996, discrete sample and profile data were collected aboard the HAKUREI MARU in the North Pacific Ocean. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, dissolved oxygen, and nutrients. These measurements were collected by researchers from the National Institute for Resources and Environment as part of the PACIFICA international collaborative project.
Use Cases
- Modeling ocean carbon uptake based on dissolved inorganic carbon and alkalinity measurements
- Analyzing nutrient cycling patterns based on nitrate, phosphate, and silicate concentrations
- Studying ocean acidification trends based on pH and carbonate system parameters
- Investigating biological productivity based on chlorophyll a measurements
Strengths
- Data covers a specific two-month cruise in 1996, providing a temporal snapshot
- Includes multiple related chemical and physical parameters for a holistic view
- Part of the PACIFICA international collaborative project for data synthesis
Limitations
- Last updated 1996-10-03 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
