Discrete sample and profile data collected from the HAKUREI MARU in the North and South Pacific Ocean from 1993-08-07 to 1993-10-05. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, dissolved oxygen, and nutrients. These data were collected by researchers from Hokkaido University and the National Institute for Resources and Environment as part of the PACIFICA project.
Use Cases
- Modeling ocean carbon uptake and acidification based on dissolved inorganic carbon and pH measurements.
- Analyzing nutrient distributions and their relationship to biological activity based on nitrate, phosphate, and silicate data.
- Studying water mass properties and ocean circulation using concurrent temperature, salinity, and pressure profiles.
Strengths
- Data includes multiple co-located chemical and physical parameters (e.g., DIC, pH, nutrients, temperature, salinity) for integrated analysis.
- Data collection is associated with a defined international project (PACIFICA) and specific research cruise (NH93-2/PACIFICA_49HG19930807).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is from a single cruise in 1993, limiting temporal analysis.
