Keppel Bay Seabed Sediment Classes from Acoustic Mapping and Sampling

Australian Ocean Data Network hosts a dataset on the geomorphology and sediment transport in Keppel Bay, Central Queensland. The data was created by classifying seabed sediments into five distinct classes using sediment sampling and acoustic seabed mapping tools. The classification is based on sediment grainsize, chemical composition, and modelled seabed shear stress from waves and tidal currents.

Use Cases

• Classifying seabed sediment types based on grainsize and composition data.
• Modeling seabed shear stress and sediment transport based on wave and tidal current data.
• Mapping the distribution of sediments and depositional characteristics in a bay environment.
• Studying the interface between a large river catchment and a continental shelf.

Strengths

• Seabed sediments are classified into five distinct, statistically-derived classes.
• Data collection combined physical sediment sampling with acoustic (sonar) seabed mapping tools.
• Analysis incorporates multiple variables: grainsize, chemical composition, and modelled seabed shear stress.

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.
• Primary file formats are PDF and HTML, which may require extraction or conversion for analysis.
