Australian Continental EEZ Seabed Sand Content Raster, 2011

Seabed sand content data for the Australian continental Exclusive Economic Zone is provided as a spatially continuous raster at 0.01 decimal degree resolution. The dataset, produced by Geoscience Australia, supersedes previous predictions with improved accuracy for national and regional scale analysis.

Use Cases

• Model sediment distribution patterns across the Australian continental EEZ using the 0-100% sand content weight percentage values.
• Assess prediction accuracy variations in areas of high seabed complexity versus dense underlying sample regions.
• Identify regions with potential data artefacts due to insufficient samples for local-scale interpretation.

Strengths

• Spatially continuous coverage of the Australian continental EEZ at 0.01 decimal degree resolution.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Intended for validated use at national and regional scales.

Limitations

• Contains artefacts in regions with insufficient underlying sample data.
• Accuracy varies based on local sample density and seabed complexity, making it inappropriate for local scales in sparse areas.
• Excludes seabed areas surrounding several Australian external territories.
