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.

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 substrate properties.
• Calibrating regional sediment transport models based on continuous raster data.

Strengths

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

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset may not be appropriate for use at local scales in areas where sample density is insufficient.
