1500-Year Record of Coastal Sediment Accumulation at Keppel Bay, Australia

A 1500-year chronology of shoreline changes is constructed from beach-ridge deposits at Keppel Bay, Queensland. The dataset includes analyses of ridge morphology, sediment texture, and geochemistry, with dating performed using optically stimulated luminescence (OSL). It was produced by Geoscience Australia Data, with results suggesting changes in sediment accumulation rates and catchment sources.

Use Cases

• Reconstructing past shoreline positions based on the chronology of beach-ridge succession.
• Analyzing changes in sediment accumulation rates over time as suggested by the OSL dating results.
• Investigating shifts in catchment sediment source areas using the geochemical data mentioned.
• Studying minor relative sea-level falls inferred from the ridge morphology and sediment record.

Strengths

• Provides a detailed 1500-year chronology for coastal change.
• Integrates multiple analysis methods: morphology, sediment texture, and geochemistry.
• Uses optically stimulated luminescence (OSL) dating, a standard geochronological technique.

Limitations

• Row count and data 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.
