Seabed Morphology Map of Zeehan Marine Park

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 by the University of Tasmania for Parks Australia. The dataset was last updated in April 2026.

Use Cases

• Classify seabed morphology features like topographic highs, lows, and planar surfaces using polygon extents and geometric attributes.
• Interpret seabed geomorphology by integrating morphology classifications with backscatter intensity and seabed imagery data.
• Analyze the distribution of key seabed features within Zeehan Marine Park using the nationally consistent classification scheme.
• Map polygon geometries derived from a 2m DEM to characterize seabed topography for habitat modeling.

Strengths

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

Limitations

• Spatial coverage is limited to a subset area within Zeehan Marine Park.
• Sample size and specific row or feature counts are unknown.
• Data freshness is unclear beyond the last platform update date.
