Seabed Morphology and Geomorphology of Beagle Marine Park, Australia

Geoscience Australia provides a geospatial data product mapping seabed morphology and geomorphology for the Beagle Marine Park in south-eastern Australia. A two-step classification system was applied to bathymetry digital elevation models, supplemented by backscatter intensity, seabed imagery, and sediment samples. The dataset includes features mapped at broad (30 m), medium, and fine (1 m) horizontal resolutions.

Use Cases

• Classify seabed morphology features based on topographic highs, lows, and planar extents derived from bathymetry DEMs.
• Interpret seabed geomorphology by integrating supplementary datasets like backscatter intensity and sediment samples.
• Support marine spatial planning with multi-resolution seabed feature layers derived from 30 m and 1 m DEMs.

Strengths

• Applies a nationally consistent two-part seabed geomorphology classification system.
• Includes multi-resolution feature layers derived from 30 m and 1 m horizontal resolution bathymetry DEMs.
• Integrates multiple supplementary data types like backscatter intensity and seabed imagery for interpretation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
