A 1500-year chronology of coastal sediment accumulation is preserved in beach deposits at Keppel Bay, Queensland, Australia. The dataset likely contains measurements of ridge morphology, sediment texture, and geochemistry, built using optically stimulated luminescence (OSL) dating. It was contributed by the Australian Ocean Data Network and last updated in April 2026.
Use Cases
- Modeling shoreline accumulation rates based on the ridge succession chronology
- Identifying catchment sediment source areas based on sediment texture and geochemistry
- Analyzing minor falls in relative sea level based on the beach ridge morphology
Strengths
- A 1500-year temporal record provides a long-term perspective on coastal change.
- The dataset integrates multiple analysis methods: ridge morphology, sediment texture, and geochemistry.
- The chronology is built using the optically stimulated luminescence (OSL) dating method.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- The description states interpretations are preliminary.
