Keppel Bay Coastal Sediment Record Spanning 1500 Years

Keppel Bay, on the central coast of Queensland, Australia, is the location for this study of beach-ridge morphology, sediment texture, and geochemistry. The dataset provides a detailed chronology built using optically stimulated luminescence (OSL) dating, covering approximately 1500 years. It was contributed by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Modeling historical shoreline accumulation rates based on the dated ridge succession.
• Analyzing changes in sediment source areas based on sediment texture and geochemistry data.
• Investigating minor relative sea-level falls over the 1500-year period suggested by the study.

Strengths

• Covers a 1500-year temporal record of coastal change.
• Includes multiple data dimensions: morphology, sediment texture, and geochemistry.
• Uses a detailed OSL dating method for chronology building.

Limitations

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