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 builds a detailed chronology for the ridge succession using optically stimulated luminescence (OSL) dating. The data, published by Geoscience Australia, suggests changes in shoreline accumulation rates, sediment sources, and minor relative sea-level falls.

Use Cases

• Modeling long-term coastal sediment accumulation rates based on the OSL-derived chronology.
• Analyzing changes in sediment source areas over time based on geochemical and textural data.
• Investigating past relative sea-level changes inferred from the beach-ridge morphology and stratigraphy.

Strengths

• Chronology spans a 1500-year period, providing a long-term environmental record.
• Analysis integrates multiple data types: ridge morphology, sediment texture, and geochemistry.
• Data is sourced from Geoscience Australia, a national geological survey.

Limitations

• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The authors note that their interpretations are preliminary.
