Seabed Morphology and Geomorphology Maps of Zeehan Marine Park, Australia

A 2026 data product from Geoscience Australia contains seabed morphology and geomorphology maps for a subset area of Zeehan Marine Park in south-eastern Australia. The maps were derived from a 2-meter resolution bathymetry DEM compiled from a multibeam survey and classified using a nationally consistent scheme. Semi-automated GIS tools were applied to map polygon extents and classify seabed features, with interpretations informed by backscatter intensity and seabed imagery where available.

Use Cases

• Classifying seabed morphology features based on polygon extents and geometric attributes.
• Mapping the distribution of key seabed geomorphology features using a standardized classification scheme.
• Informing marine spatial planning and habitat assessments within Zeehan Marine Park.
• Integrating bathymetry, backscatter, and imagery data for seabed characterisation studies.

Strengths

• Derived from a high-resolution (2 m) bathymetry digital elevation model (DEM).
• 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.
• Description metadata is limited; actual data quality requires manual inspection after download.
