Seabed Geomorphology Maps of Zeehan Marine Park

Geoscience Australia provides seabed morphology and geomorphology maps for a subset area of Zeehan Marine Park in south-eastern Australia. The data product was derived from a 2-meter resolution bathymetry digital elevation model compiled from a multibeam survey conducted by the University of Tasmania for Parks Australia. The dataset was last updated in April 2026.

Use Cases

• Classifying seabed morphology features like topographic highs, lows, and planar areas using polygon geometries from the GIS mapping.
• Interpreting seabed geomorphology by integrating bathymetry DEM data with backscatter intensity and seabed imagery.
• Applying the nationally consistent seabed geomorphology classification scheme to map the distribution of key seabed features.
• Quantitatively characterizing polygon extents and their geometric attributes to define discrete Morphology Feature types.

Strengths

• Derived from a high-resolution 2-meter horizontal resolution bathymetry DEM.
• Uses a nationally consistent seabed geomorphology classification scheme for mapping.
• Incorporates supplementary data like backscatter intensity and seabed imagery for interpretation.

Limitations

• Dataset covers only a subset area of Zeehan Marine Park, not the full park.
• Specific row counts, column details, and sample sizes are not provided.
• Relies on semi-automated tools and domain knowledge, which may introduce interpretation bias.
