Keppel Bay Coastal Sediment Accumulation Record Spanning 1500 Years

A 1500-year record of coastal sediment accumulation preserved in beach deposits at Keppel Bay, Queensland, Australia. The dataset includes analyses of ridge morphology, sediment texture, and geochemistry, with a chronology built using optically stimulated luminescence (OSL) dating. It was published by the Australian Ocean Data Network and last updated in 2026.

Use Cases

• Modeling shoreline accumulation rates based on the detailed chronology of the ridge succession.
• Analyzing changes in sediment source areas based on the sediment texture and geochemistry data.
• Investigating minor falls in relative sea level suggested by the preliminary interpretations.

Strengths

• Covers a 1500-year temporal record of coastal processes.
• Includes multiple data types: ridge morphology, sediment texture, and geochemistry.
• Chronology is built using the optically stimulated luminescence (OSL) dating method.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The interpretations are described as preliminary.
