Seabed Mud Content for the Australian Continental EEZ, 2011

Spatially continuous raster data of seabed mud content expressed as a weight percentage from 0 to 100%, covering the Australian continental Exclusive Economic Zone at a 0.01 decimal degree resolution. This dataset supersedes previous predictions with improved accuracy and is provided by the Australian Ocean Data Network. It was last updated in June 2026.

Use Cases

• Modeling sediment transport and deposition based on mud content percentage.
• Assessing seabed habitat suitability for benthic organisms based on sediment composition.
• Planning offshore infrastructure projects based on seabed sediment properties.
• Creating baseline environmental maps for marine spatial planning based on the continuous raster data.

Strengths

• Spatially continuous coverage of the Australian continental EEZ, including Tasmania.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Provides data at a 0.01 decimal degree resolution.

Limitations

• Contains artefacts in regions with insufficient underlying sample data.
• May not be appropriate for local-scale analysis where sample density is low.
• Column-level documentation is absent; field semantics must be inferred after download.
