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

A 1500-year chronology of beach-ridge morphology, sediment texture, and geochemistry from Keppel Bay, Queensland. The dataset was built using optically stimulated luminescence (OSL) dating and is provided by Geoscience Australia Data, last updated in March 2026. Preliminary results suggest changes in shoreline accumulation rates, sediment sources, and minor relative sea-level falls.

Use Cases

• Modeling long-term coastal change based on the 1500-year chronology of shoreline accumulation.
• Analyzing sediment provenance and catchment source areas based on sediment texture and geochemistry data.
• Investigating relative sea-level changes based on the interpreted minor falls recorded in the ridge succession.

Strengths

• Covers a 1500-year temporal record of coastal processes.
• Includes multiple data dimensions: ridge morphology, sediment texture, and geochemistry.
• Uses a detailed chronology built with optically stimulated luminescence (OSL) dating.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the single study site at Keppel Bay.
