Seabed Sand Content Across the Australian Continental EEZ, 2011

Spatially continuous data of seabed sand content expressed as a weight percentage from 0 to 100%, presented in 0.01 decimal degree resolution raster format. The dataset covers the Australian continental EEZ, including seabed surrounding Tasmania, and supersedes previous predictions with demonstrated improvements in accuracy. It was published by the Australian Ocean Data Network and last updated on June 4, 2026.

Use Cases

• Modeling seabed sediment distribution based on sand content percentage.
• Assessing marine habitat suitability based on sediment grain size data.
• Planning offshore infrastructure projects based on seabed composition.
• Calibrating regional sediment transport models based on continuous raster data.

Strengths

• Provides continuous raster data at 0.01 decimal degree resolution.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Covers the Australian continental EEZ, including seabed surrounding Tasmania.

Limitations

• Accuracy varies based on underlying data density and seabed complexity; artefacts occur from insufficient samples.
• Not appropriate for local-scale use in areas with insufficient sample density to detect local variation.
• Column-level documentation is absent; field semantics must be inferred after download.
