Seabed Gravel, Mud, and Sand Content in Australia's Browse Region, 2014

Geoscience Australia Data provides spatially continuous raster grids of seabed sediment composition for the Browse region within the Australian continental Exclusive Economic Zone. The dataset supersedes previous predictions with demonstrated improvements in accuracy, presenting gravel, mud, and sand content as weight percentages in a 0.0025 decimal degree resolution. It was last updated on 2026-05-14.

Use Cases

• Modeling seabed habitat suitability based on sediment composition fractions.
• Conducting basin-scale geological resource assessments based on continuous sediment distribution data.
• Planning marine infrastructure projects based on predicted seabed substrate types.
• Updating regional geological maps based on improved sediment predictions.

Strengths

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

Limitations

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