Seabed Mud Content Raster Across Australian Continental EEZ

Spatially continuous data of seabed mud content expressed as a weight percentage from 0 to 100%. The dataset covers the Australian continental Exclusive Economic Zone at a 0.01 decimal degree resolution raster format and was produced by the Australian Ocean Data Network, superseding previous predictions in 2011.

Use Cases

• Model sediment transport patterns using the mud content percentage raster layer.
• Assess seabed habitat suitability for benthic organisms based on mud fraction values.
• Validate regional-scale hydrodynamic models with the continuous sediment composition data.
• Identify areas of potential sediment accumulation or erosion by analyzing spatial mud content gradients.

Strengths

• Continuous spatial coverage across the Australian continental EEZ.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Data provided in a standardized 0.01 decimal degree resolution raster format.

Limitations

• Accuracy varies based on underlying data density and seabed complexity.
• Contains artefacts due to insufficient samples in some regions.
• Not recommended for local-scale analysis where sample density is low.
