A recent drilling program in southeast South Australia provides insight into the late Cainozoic sequence. The sequence documents a 100 km seaward shoreline progradation between Naracoorte and Robe over a period of 690,000 years or less. The data, sourced from the Australian Ocean Data Network, suggests at least 20 major high sea-level stands during this period.
Use Cases
- Modeling shoreline progradation rates based on the described 100 km seaward shift over 690,000 years.
- Analyzing sedimentary facies transitions from beach sands to aeolian sands and interdunal deposits.
- Correlating high sea-level stands with volcanic activity in the Mount Gambier-Mount Burr area mentioned in the description.
Strengths
- The description provides a specific temporal scale of 690,000 years.
- It details a concrete spatial event: a 100 km shoreline progradation between Naracoorte and Robe.
- It identifies at least 20 major high sea-level stands during the period.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The primary data formats are PDF and HTML, which may not be readily machine-readable for analysis.
