Stranded Beach Dune Chronology for Sea-Level Studies in South Australia

A sequence of stranded coastal barriers in south-east South Australia preserves a record of sea-level variations over the past 800,000 years. The dataset likely contains single-aliquot regenerative-dose optically stimulated luminescence (SAR-OSL) ages for quartz extracts from these dunes, comparing them to an existing chronology. It is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Validate and refine luminescence dating techniques based on the comparison of SAR-OSL ages with an independent chronology.
• Reconstruct past sea-level variations over the last 800,000 years based on the dated sequence of stranded coastal barriers.
• Calibrate geological models of coastal dune formation based on the reported age ranges for the Robe II (60 ka) and Robe III (100 ka) dune ranges.
• Assess the accuracy of the SAR-OSL procedure over an extended age range of 0-250 ka as described in the study.

Strengths

• Data covers a significant temporal range relevant to Quaternary studies, referencing a record spanning the past 800,000 years.
• The description indicates methodological validation, with SAR-OSL ages agreeing with expected ages within 1-sigma errors for dunes younger than 240 ka.
• Ages are tied to specific, named geological features (e.g., Robe II range, Robe III range, West Naracoorte range).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary file format is HTML, which may not be optimal for direct data analysis.
