Seabed Gravel, Mud and Sand Content in the Australian Petrel 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 Petrel sub-basin in the Australian continental EEZ at 0.0025 decimal degree resolution and supersedes previous predictions with demonstrated improvements in accuracy. It is provided by Geoscience Australia Data.

Use Cases

• Modeling seabed sediment distribution based on gravel, mud, and sand percentages.
• Planning marine infrastructure projects based on basin-scale seabed composition.
• Assessing habitat suitability for benthic organisms based on sediment type.
• Validating and updating regional geological models based on improved sediment predictions.

Strengths

• Provides data at a 0.0025 decimal degree resolution.
• Supersedes previous predictions with demonstrated improvements in accuracy.
• Covers the Petrel sub-basin within the Australian continental EEZ.

Limitations

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