Keppel Bay Coastal Sediment Record Spanning 1500 Years

Keppel Bay, on the central coast of Queensland, Australia, contains a 1500-year record of coastal sediment accumulation preserved in beach deposits. The dataset, provided by Geoscience Australia, includes analyses of ridge morphology, sediment texture, and geochemistry, with a chronology built using optically stimulated luminescence (OSL) dating. The results suggest changes in shoreline accumulation rates, sediment sources, and minor relative sea-level falls.

Use Cases

• Modeling long-term coastal change based on sediment accumulation rates.
• Analyzing shifts in sediment provenance based on geochemical data.
• Reconstructing relative sea-level history based on ridge morphology and chronology.

Strengths

• Covers a 1500-year temporal record.
• Includes multiple analysis types: morphology, texture, and geochemistry.
• Uses optically stimulated luminescence (OSL) dating for chronology.

Limitations

• Row count and data scale are unknown.
• Column-level documentation is absent; field semantics must be inferred after download.
• Interpretations are described as preliminary.
