South Pacific Ocean data collected from the HAKUREI MARU between April 12 and June 10, 1996. The dataset includes dissolved inorganic carbon, pH, alkalinity, temperature, salinity, chlorophyll a, dissolved oxygen, and nutrient concentrations. It was collected by researchers from the Geological Survey of Japan and National Institute for Resources and Environment as part of the PACIFICA project.
Use Cases
- Modeling oceanic carbon sequestration based on dissolved inorganic carbon and alkalinity measurements.
- Analyzing marine ecosystem health based on chlorophyll a and nutrient concentration data.
- Studying ocean acidification trends based on pH and carbonate system parameters.
- Calibrating oceanographic models using concurrent temperature, salinity, and hydrostatic pressure profiles.
Strengths
- Data covers a specific two-month cruise in the South Pacific Ocean from 1996-04-12 to 1996-06-10.
- Includes multiple related chemical, biological, and physical parameters measured concurrently.
- Data originates from a recognized international collaborative project (PACIFICA) supported by PICES.
Limitations
- Last updated 1996-06-10; 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.
