Seabed Mud Content Across the Australian Continental EEZ, 2011

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

Use Cases

• Modeling seabed sediment distribution based on mud content percentage.
• Assessing habitat suitability for benthic organisms based on sediment grain size.
• Planning marine infrastructure projects based on seabed composition.
• Calibrating regional oceanographic models based on seabed substrate data.

Strengths

• Provides a continuous raster layer at 0.01 decimal degree resolution.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Covers the Australian continental EEZ, including Tasmania.

Limitations

• Contains artefacts in regions with insufficient underlying sample density.
• 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.
