The Australian continental Exclusive Economic Zone, including waters around Tasmania, is covered by a spatially continuous raster dataset predicting seabed gravel content. The dataset supersedes previous predictions with improved accuracy, though accuracy varies based on underlying data density and seabed complexity. It was published by the Australian Ocean Data Network and is intended for national and regional scale use.
Use Cases
- Modeling seabed sediment distribution based on gravel weight percentage predictions.
- Assessing regional seabed composition for marine habitat studies based on the 0.01 decimal degree resolution raster.
- Planning marine infrastructure projects based on sediment data covering the continental EEZ.
- Updating national-scale sediment maps based on the dataset which supersedes previous predictions.
Strengths
- Dataset supersedes previous predictions with demonstrated improvements in accuracy.
- Provides spatially continuous data at 0.01 decimal degree resolution.
- Covers the Australian continental EEZ, including seabed surrounding Tasmania.
Limitations
- Accuracy varies and artefacts occur due to insufficient samples in some regions.
- Not appropriate for local-scale use in areas with insufficient sample density.
- Column-level documentation is absent; field semantics must be inferred after download.
