A 2000/2001 regional seafloor mapping study by Geoscience Australia's South and Southwest Regional Project. The report delineates four major geomorphological features and defines five acoustic echo facies for the Great Australian Bight area, digitized into a GIS. It was produced to support future Regional Marine Planning.
Use Cases
- Supporting Regional Marine Planning based on mapped geomorphological features and seabed character.
- Underpinning biological assessments based on GIS data of seabed acoustic facies.
- Conducting environmental assessments based on the distribution of undisturbed and disturbed sediment facies.
- Analyzing sedimentary processes in deep water based on the interpretation of acoustic facies distribution.
Strengths
- The GIS includes delineated boundaries for four major geomorphological features: continental shelf, marine terraces, continental slope, and continental rise.
- Five distinct acoustic echo facies are defined and digitized, each with key attributes captured in the GIS.
- The mapping integrates interpretation of 3.5kHz echo-sounding records, high-resolution seismic profiles, and groundtruthing against seafloor samples.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
