Seabed Morphology and Geomorphology Maps for Zeehan Marine Park, Australia

Seabed morphology and geomorphology maps for a subset of Zeehan Marine Park in south-eastern Australia. The data product was derived from a 2-meter resolution bathymetry DEM compiled from a multibeam survey by the University of Tasmania for Parks Australia. Mapping used semi-automated GIS tools and a nationally consistent classification scheme, with interpretations informed by backscatter intensity and seabed imagery.

Use Cases

• Classifying seabed morphology features based on polygon extents and geometric attributes.
• Mapping the distribution of key seabed geomorphology features using a standardized national scheme.
• Informing marine spatial planning with high-resolution bathymetric and geomorphic interpretations.

Strengths

• Derived from a high-resolution 2-meter bathymetry digital elevation model.
• Uses a nationally consistent seabed geomorphology classification scheme for mapping.
• Interpretations are supplemented by additional datasets like backscatter intensity and seabed imagery.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
