Seabed Morphology and Geomorphology Maps of Zeehan Marine Park, Australia

A 2-meter horizontal resolution bathymetry DEM underpins this seabed feature map for a subset of Zeehan Marine Park. The University of Tasmania conducted the multibeam survey for Parks Australia, and Geoscience Australia's semi-automated GIS tools were applied to classify morphology and geomorphology. The classification follows a nationally consistent scheme, with interpretations informed by backscatter intensity and seabed imagery where available.

Use Cases

• Classifying seabed morphology features (topographic high, low, planar) based on polygon geometries derived from bathymetry.
• Interpreting seabed geomorphology by applying domain knowledge and supplementary datasets like backscatter intensity.
• Mapping the distribution of key seabed features for marine park management using a nationally consistent classification scheme.
• Characterizing seabed topography quantitatively in a GIS environment using semi-automated mapping tools (GA-SaMMT).

Strengths

• Derived from a high-resolution (2 m) bathymetry digital elevation model (DEM).
• Applies a nationally consistent, peer-reviewed seabed geomorphology classification scheme.
• Geomorphic interpretations are informed by multiple data sources, including backscatter intensity and seabed imagery.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data covers only a subset area of Zeehan Marine Park, not the entire park.
• Description metadata is limited; actual data quality and field semantics require manual inspection after download.
