Discrete sample and profile observations collected from the HAKUREI MARU in the North and South Pacific Ocean from April to June 1993. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, chlorophyll A, dissolved oxygen, and nutrient concentrations. These data were collected by Yutaka W. Watanabe and Masashi Arita of 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 cycling and phytoplankton productivity based on nitrate, phosphate, silicate, and chlorophyll A data.
- Studying physical oceanographic properties and their correlation with chemical parameters based on temperature, salinity, and hydrostatic pressure profiles.
Strengths
- Data covers a specific two-month cruise in 1993, providing a focused temporal snapshot.
- Includes multiple related chemical, biological, and physical parameters for integrated analysis.
- Part of the international PACIFICA project for data synthesis of ocean interior carbon.
Limitations
- Last updated 1993-06-11 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.
