A raster dataset provides spatially continuous seabed sand content expressed as a weight percentage from 0 to 100%. It covers the Australian continental Exclusive Economic Zone, including Tasmania, at a 0.01 decimal degree resolution. The dataset supersedes previous predictions with improved accuracy, though artifacts occur in regions with insufficient samples.
Use Cases
- Model seabed sediment composition based on sand weight percentage data.
- Analyze marine habitat suitability based on sediment type distribution.
- Assess seabed complexity and data accuracy variations across the EEZ.
- Plan marine sampling campaigns in areas flagged for insufficient data density.
Strengths
- Spatially continuous coverage of the Australian continental EEZ.
- Supersedes previous predictions with demonstrated improvements in accuracy.
- Provides data at a 0.01 decimal degree resolution raster format.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Accuracy varies and artifacts occur in regions with insufficient underlying samples.
- The dataset may not be appropriate for use at local scales in low-sample-density areas.
