Keppel Bay Seabed Sediment Classes Based on Grainsize and Stress

A study assessed sediment distribution in Keppel Bay, a macrotidal environment connecting the Fitzroy River catchment to the Great Barrier Reef shelf. The research used sediment sampling and acoustic seabed mapping to classify the seabed into five distinct classes based on grainsize, chemical composition, and modelled seabed shear stress. The dataset is provided by Geoscience Australia Data and was last updated on 2026-03-25.

Use Cases

• Classifying seabed sediment types based on grainsize and chemical composition mentioned in the description.
• Modeling seabed shear stress and sediment transport based on wave and tidal current influences.
• Mapping the interface between a large river catchment and a continental shelf environment.
• Validating acoustic seabed mapping tools with physical sediment samples.

Strengths

• Seabed classified into five distinct sediment classes using statistical techniques.
• Data combines physical sediment sampling with acoustic (sonar) seabed mapping.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
