Seabed Morphology and Geomorphology Maps of Zeehan Marine Park, Australia

A 2-meter horizontal resolution bathymetry DEM compiled from a multibeam survey by the University of Tasmania underpins this seabed morphology and geomorphology data product for Zeehan Marine Park. Semi-automated GIS mapping tools were applied to classify polygon extents into topographic highs, lows, and planar areas, with geometric attributes used to define discrete morphology feature types. The data product, last updated on 2026-06-04, is hosted by the Australian Ocean Data Network.

Use Cases

• Map seabed geomorphology features based on the described classification scheme.
• Analyze seabed morphology polygons (topographic high, low, planar) derived from the 2m bathymetry DEM.
• Characterize marine habitats using the integrated backscatter intensity and seabed imagery mentioned in the description.
• Support marine spatial planning for Zeehan Marine Park using the nationally consistent classification framework.

Strengths

• Derived from a 2-meter horizontal resolution bathymetry DEM.
• Uses a nationally consistent seabed geomorphology classification scheme.
• Incorporates supplemental data like backscatter intensity and seabed imagery where available.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to data_gov_au, focusing on a subset of Zeehan Marine Park.
