Seabed Morphology and Geomorphology of Zeehan Marine Park, Australia

Seabed morphology and geomorphology maps for a subset of Zeehan Marine Park, derived from a 2-meter resolution bathymetry DEM. The data product was created by Geoscience Australia using semi-automated GIS mapping tools applied to multibeam survey data. It classifies seabed features using a nationally consistent classification scheme, with interpretations informed by backscatter intensity and seabed imagery.

Use Cases

• Classifying seabed geomorphology features based on the described national classification scheme.
• Mapping the distribution of topographic highs, lows, and planar surfaces using the derived polygon extents.
• Characterizing seabed habitats for marine park management based on the interpreted geomorphic features.
• Integrating bathymetry with backscatter and imagery data for enhanced seabed interpretation as mentioned in the description.

Strengths

• Derived from a high-resolution 2-meter bathymetry DEM.
• Uses a nationally consistent seabed geomorphology classification scheme.
• 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.
• Data coverage is limited to a subset area of Zeehan Marine Park.
