Seabed Mud Content Across the Australian Continental EEZ

Australian continental Exclusive Economic Zone (EEZ) and surrounding Tasmania is covered by a raster dataset predicting seabed mud content as a weight percentage (0-100%). The data has a 0.01 decimal degree resolution and supersedes previous predictions with demonstrated improvements in accuracy. It is intended for national and regional scale analysis but may contain artefacts in areas with insufficient sample density.

Use Cases

• Modeling benthic habitats based on sediment grain size distribution.
• Regional environmental impact assessments for offshore development projects.
• Calibrating and validating broader oceanographic or geological models.
• Planning future seabed sampling campaigns to address data-sparse regions.

Strengths

• Supersedes previous predictions with demonstrated improvements in accuracy.
• Provides spatially continuous coverage at a 0.01 decimal degree resolution.
• Explicitly defines geographic scope (Australian continental EEZ) and exclusions.

Limitations

• Contains artefacts due to insufficient sample density in some regions, limiting local-scale use.
• Metadata on row count, file size, license, and specific author is unavailable.
• Does not include Australia's offshore territories like Macquarie Island or the Antarctic jurisdiction.
