Pleistocene Sea-Level Changes in Southeast South Australia, 690,000-Year Record

A 690,000-year geological record from southeast South Australia documents shoreline progradation and sea-level changes. The dataset, from a drilling program by Geoscience Australia, reveals a regressive sequence of beach, marine, and aeolian sands. It suggests at least 20 major high sea-level stands during this period.

Use Cases

• Modeling past sea-level changes based on the described sedimentary sequence.
• Studying coastal progradation rates using the 100 km shoreline shift mentioned.
• Correlating regional uplift and volcanic activity with sedimentary facies described.
• Reconstructing paleoenvironments from the bay, estuarine, lagoonal, and lacustrine facies transitions.

Strengths

• Covers a specific 690,000-year time period for analysis.
• Documents a 100 km seaward shoreline progradation between Naracoorte and Robe.
• Identifies at least 20 major high sea-level stands within the sequence.

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 PDF/HTML documents, not a structured tabular format.
