From August to October 1994, discrete sample and profile data were collected from the HAKUREI MARU research vessel in the North and South Pacific Ocean. The data include dissolved inorganic carbon, pH, alkalinity, temperature, salinity, chlorophyll A, and nutrient concentrations. It was collected by researchers from the Geological Survey of Japan and the National Institute for Resources and Environment as part of the PACIFICA international synthesis project.
Use Cases
- Modeling ocean acidification trends based on pH and dissolved inorganic carbon measurements.
- Studying marine primary productivity based on chlorophyll A and nutrient concentration data.
- Analyzing water mass properties and circulation based on temperature, salinity, and hydrostatic pressure profiles.
- Calibrating satellite-derived ocean color data with in-situ chlorophyll A measurements.
Strengths
- Data covers a specific two-month cruise in 1994, providing a temporal snapshot.
- Includes multiple related chemical and physical parameters (e.g., DIC, pH, alkalinity, nutrients, temperature, salinity) for integrated analysis.
- Collected as part of the PACIFICA international collaborative project for data synthesis.
Limitations
- Last updated 1994-10-06 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.
