Seabed Mud Content Across Australia's Continental EEZ, 2011

Spatially continuous data of seabed mud content expressed as a weight percentage from 0 to 100% in 0.01 decimal degree resolution raster format. The dataset covers the Australian continental EEZ, including Tasmania, and supersedes previous predictions with demonstrated improvements in accuracy. It was published by Geoscience Australia Data and last updated on March 25, -2026.

Use Cases

• Modeling seabed habitat suitability based on sediment mud content.
• Creating regional-scale marine geology maps based on continuous raster data.
• Assessing sediment transport and deposition patterns based on mud percentage distribution.
• Planning offshore infrastructure projects based on seabed sediment properties.

Strengths

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

Limitations

• Accuracy varies based on underlying data density and seabed complexity; artefacts occur in regions with insufficient samples.
• The dataset may not be appropriate for use at local scales where sample density is insufficient.
• Column-level documentation is absent; field semantics must be inferred after download.
