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 chronostratigraphy of seven beach ridges, with optical dating providing ages and inferred sea-level positions. The data record changes in shoreline accretion rates and sediment supply, including potential impacts from European settlement.
Use Cases
- Modeling shoreline progradation rates based on optically dated beach ridge sequences.
- Reconstructing relative sea-level changes over the last 1,700 years based on ridge morphology and dating.
- Analyzing changes in sediment supply and coastal accretion phases, potentially linked to human settlement.
- Comparing historical coastal erosion and accretion regimes based on the chronology of the modern beach and preceding ridges.
Strengths
- Provides a chronological record spanning approximately 1,700 years.
- Includes specific progradation rates, such as ~0.16 m yr-1 and ~0.40 m yr-1, derived from optical dating.
- Documents a clear morphological change in ridge spacing and amplitude between older and younger 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 data_gov_au, being specific to a single site in southeastern Queensland.
