High-resolution bathymetry and acoustic backscatter data from 2015, covering an area greater than 1500 km² of the Perth submarine canyon off southwest Australia. Geoscience Australia applied a new genetic classification system to map geomorphic features and potential benthic habitats. Results were presented at the 2017 American Geophysical Union Fall Meeting.
Use Cases
- Classifying seafloor geomorphic features based on a nested genetic classification approach.
- Mapping potential benthic habitats using high-resolution bathymetry and acoustic backscatter.
- Analyzing submarine canyon morphology based on topographic metrics and shelf-incising status.
Strengths
- Covers an area greater than 1500 km² from 170 m to 4700 m water depth.
- Uses 20 m resolution bathymetry and acoustic backscatter data acquired in 2015.
- Applies a structured classification framework linking processes and morphology.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
