Seabed Morphology and Geomorphology Maps for Zeehan Marine Park, Australia

Zeehan Marine Park in south-eastern Australia contains seabed morphology and geomorphology maps derived from a 2-meter resolution bathymetry DEM. The data product was created by the University of Tasmania for Parks Australia using semi-automated GIS mapping tools and a nationally consistent classification scheme. It was last updated on 2026-06-23.

Use Cases

• Classify seabed morphology features based on topographic highs, lows, and planar extents.
• Characterize seabed geomorphology by integrating bathymetry with backscatter and seabed imagery.
• Map marine park habitats using a standardized national geomorphology classification framework.

Strengths

• Derived from a high-resolution (2 m horizontal) bathymetry digital elevation model.
• Uses a nationally consistent seabed geomorphology classification scheme.
• Interpretations are informed by supplemental datasets like backscatter intensity and seabed imagery.

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 the specific multibeam survey area.
