A geospatial dataset classifies the seabed sediments of Keppel Bay, Central Queensland, into five distinct classes. The classification is based on sediment grainsize, chemical composition, and modeled seabed shear stress from waves and tidal currents. The data was produced by Geoscience Australia using sediment sampling and acoustic seabed mapping tools.
Use Cases
- Modeling sediment transport pathways based on classified seabed sediment types.
- Analyzing the influence of waves and tidal currents on seabed composition based on shear stress models.
- Mapping the interface between a large river catchment and a continental shelf based on sediment distribution.
- Classifying seabed habitats using statistical techniques applied to grainsize and chemical data.
Strengths
- Data is derived from a combination of physical sediment sampling and acoustic seabed mapping tools.
- Statistical techniques were used to classify the seabed into five distinct sediment classes.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
