Predicted Seabed Mud Content for Darwin Harbour, 10-Meter Resolution

395 seabed samples and nine environmental variables underpin a spatially continuous prediction grid for mud content in Darwin and Bynoe Harbours. The dataset, compiled from surveys between 2011 and 2017, supersedes previous predictions with a demonstrated 198.3% increase in predictive accuracy for mud compared to the Inverse Distance Weighting method. Data are provided by Geoscience Australia, the Australian Institute of Marine Science, and the Northern Territory Government's Department of Environment and Natural Resources.

Use Cases

• Creating thematic habitat maps based on predicted seabed composition.
• Informing marine resource management decisions based on baseline environmental data.
• Modeling sediment transport and distribution patterns based on high-resolution multibeam sonar data.
• Assessing the accuracy of seabed property prediction methods based on the reported VEcv metric.

Strengths

• Predictive accuracy is reported as very high, with a VEcv of 62% for mud.
• Predictive accuracy for mud was increased by 198.3% compared to a commonly used method.
• Data is derived from a compilation of multiple surveys conducted between 2011 and 2017.
• Spatial predictions are provided at a 10-meter resolution raster grid.

Limitations

• Absences in predictions occur due to non-availability of associated predictive variables.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
