Predicted Seabed Gravel, Mud and Sand Content in Australia's Vlaming Sub-Basin

Spatially continuous data of seabed gravel, mud, and sand content expressed as a weight percentage from 0 to 100%. The dataset covers the Vlaming sub-basin in the Australian continental EEZ and is presented in 0.0025 decimal degree resolution raster grids. This dataset supersedes previous predictions with demonstrated improvements in accuracy and is provided by Geoscience Australia.

Use Cases

• Modeling seabed habitat suitability based on sediment composition fractions.
• Analyzing sediment transport patterns based on spatially continuous gravel, mud, and sand percentages.
• Planning marine infrastructure projects based on predicted seabed substrate properties.
• Calibrating regional oceanographic models based on updated sediment distribution data.

Strengths

• Provides continuous predictions for three sediment fractions (gravel, mud, sand) across the entire basin.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Data is provided at a 0.0025 decimal degree spatial resolution.

Limitations

• Accuracy varies based on underlying sample density and seabed complexity, with artefacts present in undersampled regions.
• Intended for basin-scale use and may not be appropriate for local-scale analysis in areas with insufficient samples.
• Column-level documentation is absent; field semantics must be inferred after download.
