A 690,000-year geological sequence from southeast South Australia documents shoreline changes between Naracoorte and Robe. The data, from a recent drilling program, includes sandy and fine-grained facies deposited in beach, marine, aeolian, and lagoonal environments. It is provided by the Australian Ocean Data Network and suggests at least 20 major high sea-level stands during the period.
Use Cases
- Modeling past sea-level changes based on the described regressive sequence and high sea-level stands.
- Analyzing sediment facies transitions based on described beach, marine, aeolian, and lagoonal deposits.
- Studying regional tectonic uplift based on its relationship to volcanic activity near Mount Gambier-Mount Burr.
Strengths
- Covers a specific 690,000-year time period for detailed paleoclimate study.
- Documents a 100 km seaward progradation of the shoreline, providing a clear spatial scale.
- Identifies at least 20 major high sea-level stands, offering a quantifiable record of change.
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, focusing on a single Australian region.
