The Coral Sea, North Pacific Ocean, South Pacific Ocean, and Tasman Sea are covered by this dataset of discrete ocean measurements collected from the HAKUREI MARU between April 14 and June 12, 1995. It includes variables such as dissolved inorganic carbon, alkalinity, pH, salinity, temperature, nutrients, and chlorophyll A, collected using CTD and bottle instruments. The data were collected by researchers from the Geological Survey of Japan and 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.
- Analyzing nutrient cycling in ocean ecosystems based on nitrate, phosphate, and silicate data.
- Studying the relationship between physical oceanography and biological productivity based on temperature, salinity, and chlorophyll A.
- Calibrating regional carbon budget models based on alkalinity and dissolved inorganic carbon profiles.
Strengths
- Data covers a multi-region cruise across the Coral Sea, North Pacific Ocean, South Pacific Ocean, and Tasman Sea.
- Includes a suite of 12 key chemical, biological, and physical oceanographic variables.
- Data collection is part of the PACIFICA international collaborative project for Pacific Ocean interior carbon synthesis.
Limitations
- Last updated 1995-06-12 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.
