Beachmere in southeastern Queensland, Australia provides a record of shoreline changes over the last 1,700 years. The dataset is based on the morphology and chronostratigraphy of seven beach ridges, with optical dating used to determine their ages. It was published by the Australian Ocean Data Network and last updated in June 2026.
Use Cases
- Modeling historical shoreline progradation rates based on optical ages of beach ridges.
- Analyzing changes in relative sea level over the last 1,700 years based on ridge stratigraphy.
- Investigating the impact of increased sediment supply, potentially from European settlement, on coastal accretion patterns.
- Comparing phases of regular ridge formation with periods of rapid, closely spaced ridge emplacement.
Strengths
- Covers a specific 1,700-year time span at a single site.
- Provides quantified progradation rates, such as ~0.16 m yr-1 and ~0.40 m yr-1.
- Identifies a distinct change in ridge spacing and morphology between older and younger ridges.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Column-level documentation is absent; field semantics must be inferred after download.
- Data may reflect geographic bias inherent to data_gov_au, being limited to one location in Queensland.
