Beach ridges at Keppel Bay, central Queensland, Australia, preserve a record of sediment accumulation from the historical period back to middle Holocene times. The dataset likely contains optically stimulated luminescence (OSL) ages indicating deposition periods approximately 1500, 1000, 450, and 230 years before present, and estimates of sediment mass stored in the strandplain. It was aggregated by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Modeling sediment accumulation rates based on beach ridge accretion units and OSL ages.
- Analyzing the impact of cyclone-induced floods on coastal progradation based on the described flood recurrence interval.
- Investigating changes in sediment provenance based on trace-element composition linked to catchment soil types.
- Correlating coastal sedimentation records with broader late Holocene climate phases in eastern Australia.
Strengths
- OSL ages provide temporal markers for deposition periods approximately 1500, 1000, 450, and 230 years BP.
- Description includes a specific estimate that the strandplain traps the equivalent of 79% of the estimated long-term average annual bedload.
- Analysis links sediment provenance changes to historical land-use changes like vegetation clearing.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
