Over the past 800 ka, a sequence of stranded coastal barriers in south-east South Australia preserves a record of sea-level variations. This dataset likely contains quartz SAR-OSL ages determined on quartz extracts from these dunes, comparing them with an existing chronology. The data is presented by the Australian Ocean Data Network.
Use Cases
- Validate luminescence dating methods based on comparisons with independent chronology.
- Analyze sea-level variations over the past 800 ka based on the preserved record in stranded coastal barriers.
- Study the extended age range of 0-250 ka for quartz SAR-OSL dating accuracy.
- Compare the Robe II (60 ka) and Robe III (100 ka) dune ranges based on the reported ages.
- Assess the monotonic increase in OSL ages from the Robe II range to the West Naracoorte range.
Strengths
- The dataset is based on a record spanning the past 800 ka.
- It includes comparisons of SAR-OSL ages with an independent chronology.
- The description provides specific age ranges for the Robe II (60 ka) and Robe III (100 ka) dunes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data may reflect geographic bias inherent to data_gov_au.
