Keppel Bay Seabed Sediment Classes and Geomorphology

Keppel Bay in Central Queensland, Australia, represents a macrotidal interface between the Fitzroy River catchment and the Great Barrier Reef shelf. The dataset contains a classification of seabed sediments into five distinct classes, derived from sediment sampling and acoustic seabed mapping. The study was contributed 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 and sediment transport based on wave and tidal current data.
• Mapping the geomorphology of a macrotidal bay environment for coastal management.
• Analyzing the interface between a large river catchment and a continental shelf.

Strengths

• Seabed sediments are classified into five distinct classes using statistical techniques.
• Data combines multiple collection methods: sediment sampling and acoustic seabed mapping.
• Focuses on a defined macrotidal environment at the Fitzroy River and Great Barrier Reef interface.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in HTML and PDF formats, which may require extraction for analysis.
