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

A recent drilling program in southeast South Australia provides new insight into the late Cainozoic sequence. The data suggests at least 20 major high sea-level stands over the past 690,000 years, resulting in a 100 km seaward shoreline progradation between Naracoorte and Robe. The sequence is described by the Australian Ocean Data Network and includes sandy and fine-grained facies deposited under various marine and terrestrial conditions.

Use Cases

• Modeling Pleistocene sea-level fluctuations based on the described regressive sequence.
• Analyzing sedimentary facies transitions from beach sands to aeolian and interdunal deposits.
• Correlating regional uplift and volcanic activity with coastal progradation patterns.
• Reconstructing paleoenvironments from bay, estuarine, lagoonal, and lacustrine sediment descriptions.

Strengths

• Describes a 690,000-year geological sequence with a defined 100 km shoreline progradation.
• Identifies at least 20 major high sea-level stands during the Pleistocene period.
• Provides detailed facies descriptions including beach sands, aeolian sands, and interdunal deposits.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is presented in PDF/HTML formats, which may require extraction for computational analysis.
