Predicted Seabed Gravel, Mud and Sand Content in the Vlaming Sub-Basin

Spatially continuous data of seabed gravel, mud, and sand content expressed as weight percentages from 0 to 100%. The dataset covers the Vlaming sub-basin in the Australian continental EEZ at 0.0025 decimal degree resolution. This dataset supersedes previous predictions with demonstrated improvements in accuracy, though accuracy varies based on sample density and seabed complexity.

Use Cases

• Modeling seabed sediment distribution based on spatially continuous gravel, mud, and sand percentages.
• Assessing marine habitat suitability based on predicted sediment fractions.
• Planning offshore infrastructure projects based on basin-scale seabed composition.
• Validating geological models of the Vlaming sub-basin based on updated sediment predictions.

Strengths

• Supersedes previous predictions with demonstrated improvements in accuracy.
• Provides three sediment fractions (gravel, mud, sand) as continuous weight percentages.
• Offers data at a 0.0025 decimal degree resolution raster grid format.

Limitations

• Accuracy varies and artefacts occur due to insufficient samples in some regions.
• Intended for basin scale; may not be appropriate for smaller-scale analysis in data-sparse areas.
• Column-level documentation is absent; field semantics must be inferred after download.
