Seabed Morphology and Geomorphology Maps for Zeehan Marine Park

This data product contains seabed morphology and geomorphology maps for a subset area of Zeehan Marine Park in south-eastern Australia. The maps were derived from a 2-meter resolution bathymetry DEM compiled from a multibeam survey and classified using a nationally consistent scheme. The Australian Ocean Data Network hosts the data, which was last updated on 2026-05-05.

Use Cases

• Classify seabed morphology features based on polygon geometries and topographic attributes.
• Interpret seabed geomorphology by integrating bathymetry, backscatter intensity, and seabed imagery.
• Map the distribution of key seabed features within a marine park using semi-automated GIS tools.
• Characterize seabed topography (highs, lows, planar areas) from a high-resolution digital elevation model.

Strengths

• Uses a 2-meter horizontal resolution bathymetry DEM for detailed seabed mapping.
• Applies a nationally consistent seabed geomorphology classification scheme.
• Integrates multiple data sources, including backscatter intensity and seabed imagery, to inform interpretations.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
