Beagle Marine Park Seabed Geomorphology And Morphology Features

Beagle Marine Park in south-eastern Australia contains geospatial seabed morphology and geomorphology data for marine park management. The dataset was produced by Geoscience Australia using a two-step classification system applied to bathymetry digital elevation models at 30 m and 1 m resolutions. It was published by the Australian Ocean Data Network and last updated in April 2026.

Use Cases

• Classify seabed morphology features like topographic highs and lows using polygon extents and geometric attributes from the GIS mapping.
• Interpret seabed geomorphology by integrating backscatter intensity, seabed imagery, and sediment samples with the bathymetry DEM layers.
• Compare broad-scale seabed features derived from the 30 m resolution DEM with fine-scale features from 1 m resolution DEMs for multi-resolution analysis.
• Apply the two-part seabed geomorphology classification system (Morphology Feature types and geomorphic characterisation) to standardize marine habitat mapping.

Strengths

• Multi-resolution data layers derived from 30 m and 1 m horizontal resolution digital elevation models
• Classification follows a nationally consistent two-part seabed geomorphology system
• Supplementary data includes backscatter intensity, seabed imagery, sediment samples, and sub-bottom profiles

Limitations

• Specific row counts, column counts, and total data size are unknown
• Geographic scope is limited solely to the Beagle Marine Park in Australia
• Data freshness is unclear as the last platform update may not reflect original survey dates
