The Rates of Shoreline Progradation dataset provides a chronostratigraphic record of beach ridge formation at Beachmere, southeastern Queensland, Australia. It contains optical ages for seven beach ridges, documenting changes in shoreline accretion and relative sea level over the last 1,700 years. The dataset is hosted by the Australian Ocean Data Network.
Use Cases
- Model shoreline progradation rates based on optical ages of beach ridges.
- Analyze changes in relative sea level over the last 1,700 years.
- Study the impact of sediment supply changes, such as those associated with European settlement, on coastal accretion.
Strengths
- Provides optical ages for seven distinct beach ridges.
- Covers a temporal range of 1,700 years.
- Includes quantified progradation rates, such as ~0.16 m yr-1 and ~0.40 m yr-1.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
