South-eastern Australian saline lakes provide data on ostracod species occurrences linked to ionic water composition. The dataset likely contains records of ostracod faunas set against physiologically important ionic ratios, such as Na+/H+ and alkalinity/Cl-, within a marine-meteoric framework. Data was published by Geoscience Australia and last updated on 2026-03 25.
Use Cases
- Modeling species distribution based on ionic ratios like Na+/H+ and Na+/Ca2+ mentioned in the description.
- Analyzing the relationship between ostracod occurrence and the alkalinity/Cl- activity ratio boundary described.
- Investigating the influence of halite recycling and solute evolution pathways on aquatic organism communities.
- Correlating geochemical processes with biodiversity for other salt-water organisms like zooplankton and diatoms.
Strengths
- Data is grounded in the Eugster-Jones-Hardie models of solute evolution, providing a theoretical geochemical framework.
- Links biological occurrences to specific, measurable ionic ratios and activity boundaries, such as an alkalinity/Cl- ratio of ~-2.3.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
