The Australian Ocean Data Network provides hydrogeochemical data on groundwater in the upper Hunter River valley of New South Wales. The description details chemical processes like silicate dissolution and ion exchange, focusing on regional recharge zones and aquifers in Triassic, Carboniferous, and Permian rocks. The dataset was last updated on 2026-04-16.
Use Cases
- Modeling groundwater-rock interactions based on described silicate and carbonate dissolution/precipitation reactions.
- Assessing groundwater salinity sources based on the described legacy of Permian marine salts and sulphide oxidation.
- Mapping mineral stability fields in aquifers based on the described kaolinite and Ca-montmorillonite equilibrium.
- Analyzing solute distribution patterns based on the described log-normal and bimodal distributions of key ions.
Strengths
- Detailed description of hydrogeochemical processes and geological formations influencing groundwater chemistry.
- Focus on a specific, well-defined geographical region: the upper Hunter River valley in New South Wales.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data is provided as HTML and PDF files, which may require extraction for analysis.
