Coastal Sediment Accumulation Record for Keppel Bay, Queensland, 1500 Years

A 1500-year record of coastal sediment accumulation preserved in beach deposits at Keppel Bay, Queensland, Australia. The dataset was published by the Australian Ocean Data Network and last updated in June 2026. It examines ridge morphology, sediment texture, and geochemistry, with a chronology built using optically stimulated luminescence (OSL) dating.

Use Cases

• Modeling long-term shoreline change rates based on the sediment accumulation chronology.
• Analyzing shifts in sediment source areas based on geochemistry and texture data.
• Investigating relative sea-level changes based on the interpreted minor falls in sea level.
• Studying coastal geomorphology and beach-ridge plain development.

Strengths

• Covers a 1500-year temporal record, providing long-term context.
• Includes multiple data dimensions: morphology, texture, and geochemistry.
• Uses optically stimulated luminescence (OSL) dating for chronology.

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 interpretations are preliminary.
