Keppel Bay Seabed Sediment Classes Based on Grainsize and Acoustic Mapping

A study of sediment distribution in Keppel Bay, a macrotidal environment at the interface of the Fitzroy River catchment and the Great Barrier Reef shelf. Researchers classified seabed sediments into five distinct classes using statistical techniques on grainsize, chemical composition, and modelled seabed shear stress data. The dataset is hosted by the Australian Ocean Data Network and was last updated in April 2026.

Use Cases

• Classifying seabed sediment types based on grainsize and chemical composition.
• Modeling seabed shear stress from waves and tidal currents.
• Mapping the interface between a large river catchment and a continental shelf.
• Analyzing sediment depositional characteristics in a macrotidal bay.

Strengths

• Seabed classification into five distinct sediment classes.
• Data combines physical sampling with acoustic seabed mapping tools.
• Analysis includes modelled seabed shear stress from waves and currents.

Limitations

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