Ostracod Species Occurrences in South-eastern Australian Saline Lakes

Ostracod occurrence data from south-eastern Australian saline lakes, analyzed within a marine-meteoric chemical framework. The dataset relates species composition to ionic ratios and geochemical pathways defined by Eugster-Jones-Hardie models. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling species distribution based on ionic ratios like Na+/H+ and alkalinity/Cl-
• Analyzing ostracod tolerance ranges to specific geochemical solute pathways
• Investigating the biological impact of halite recycling processes on lake fauna
• Comparing ostracod community changes across chemical boundaries defined by mixing models

Strengths

• Data is framed within established Eugster-Jones-Hardie geochemical models, providing a theoretical context.
• Findings link specific ionic ratios, such as an Alkalinity/Cl- activity ratio of ~-2.3, to major biological divisions in the fauna.
• Analysis extends relevance to other aquatic organisms like zooplankton and diatoms, suggesting broader applicability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
