Seabed Gravel Content for the Australian Continental EEZ, 2011

The Australian continental Exclusive Economic Zone, including waters around Tasmania, is covered by this spatially continuous raster dataset. It provides seabed gravel content, expressed as a weight percentage from 0 to 100%, at a 0.01 decimal degree resolution. This dataset supersedes previous predictions with improved accuracy and was made available by the Australian Ocean Data Network.

Use Cases

• Modeling seabed habitat suitability based on sediment gravel content.
• Conducting regional resource assessments for marine aggregates based on gravel distribution.
• Planning marine infrastructure projects based on seabed substrate characteristics.
• Analyzing sediment transport patterns at a continental scale.

Strengths

• Spatially continuous coverage of the Australian continental EEZ at 0.01 decimal degree resolution.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Provides a specific measurement (weight percentage) ranging from 0 to 100%.

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.
