Late Cainozoic Sequence of Southeast South Australia and Pleistocene Sea-Level Changes

Southeast South Australia's geological record from a recent drilling program provides insight into late Cainozoic sequences. The data likely contains details on sedimentary facies and sea-level changes over a period of 690,000 years or less. It was published by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling shoreline progradation based on the described 100 km seaward shift over 690,000 years.
• Correlating sedimentary facies (beach, aeolian, interdunal) with sea-level stands mentioned in the description.
• Reconstructing Pleistocene paleoenvironments based on described transitions from bay/estuarine to lagoonal and lacustrine conditions.
• Analyzing the relationship between regional uplift, volcanic activity, and eustatic sea-level changes as described.

Strengths

• Description provides a specific temporal context of 690,000 years or less.
• Identifies a clear geographic scope between Naracoorte and Robe in South Australia.
• Suggests evidence for at least 20 major high sea-level stands during the studied period.

Limitations

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