Predicted Seabed Sediment Content in the Timor Sea, 10-Meter Resolution

2018 spatially continuous data of seabed gravel, mud, and sand content expressed as a weight percentage from 0 to 100%. The dataset covers eight areas in the Timor Sea region within the Australian continental EEZ, presented in 10-meter resolution raster grids. This research was supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub.

Use Cases

• Modeling seabed habitat suitability based on sediment composition fractions.
• Analyzing sediment distribution patterns for marine spatial planning.
• Validating and improving sediment prediction algorithms based on the provided accuracy metrics (VEcv).
• Assessing geological and environmental changes in the Timor Sea continental shelf.

Strengths

• Provides specific prediction accuracy metrics: VEcv = 71% for mud, 72% for sand, and 42% for gravel.
• Offers high-resolution (10-meter) spatially continuous data for three sediment fractions.
• Supersedes previous predictions with demonstrated improvements in accuracy.

Limitations

• Contains artefacts such as horizontal and vertical lines resulting from noise in predictive variables like backscatter data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
