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

A 1500-year record of coastal sediment accumulation preserved in beach deposits at Keppel Bay, Queensland, Australia. The dataset, hosted by the Australian Ocean Data Network, examines 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 shoreline change based on sediment accumulation rates.
• Analyzing shifts in sediment provenance based on geochemical data.
• Investigating relative sea-level history based on beach ridge morphology and chronology.

Strengths

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

Limitations

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