The Australian Ocean Data Network hosts a dataset detailing shoreline changes at Beachmere, southeastern Queensland, Australia, over the last 1,700 years. It is based on the morphology and optical dating of seven beach ridges, providing a record of shoreline accretion rates and relative sea-level changes. The data was last updated on 2026-06-16.
Use Cases
- Modeling shoreline progradation rates based on optically dated beach ridge sequences.
- Analyzing changes in relative sea level over the last 1,700 years based on ridge elevation data.
- Investigating the impact of increased sediment supply, potentially linked to European settlement, on rapid shoreline accretion.
- Assessing the transition from a progradational to an erosional coastal regime based on the age of the modern beach ridge.
Strengths
- Provides a high-resolution chronological record spanning 1,700 years.
- Quantifies specific progradation rates, such as ~0.16 m/yr and ~0.40 m/yr for different periods.
- Identifies a distinct geomorphic change marked by a ~200 m wide intertidal flat between ridges.
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 a single site (Beachmere).
