South-east South Australia's stranded coastal barrier sequence preserves a record of sea-level variations over the past 800,000 years. This dataset presents new single-aliquot regenerative-dose optically stimulated luminescence (SAR-OSL) ages for quartz extracts from these dunes, testing the method's accuracy over a 0-250 ka range against an existing chronology. The data, associated with the Australian Ocean Data Network, was last updated in April 2026.
Use Cases
- Calibrating quartz SAR-OSL dating methods based on comparisons with an independent chronology.
- Reconstructing sea-level history over the past 800,000 years based on the dated coastal barrier sequence.
- Analyzing the accuracy of luminescence dating for dunes older than 240 ka based on reported error limits.
- Studying the geomorphological evolution of the Robe and Naracoorte ranges based on the monotonic age progression.
Strengths
- Dataset is tied to a well-studied coastal sequence that preserves a record spanning approximately 800,000 years.
- Ages are compared against an independent chronology, allowing for method validation.
- Specific age results are provided for features like the Robe II range (60 ka) and Robe III (100 ka).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- The primary data format is HTML, which may require parsing to extract structured data.
