Abstract

This resource contains backscatter data acquired during the WA Margins Reconnaissance survey, GA-2476 from October 2008 to January 2009 onboard the RV Sonne as part of the Energy Security Program. Almost 230,000 km² of multibeam bathymetry was acquired over the duration of the survey including all transits. Seafloor features revealed by the backscatter and swath bathymetry have shown that geomorphology of the study areas is diverse. The continental slope of the west Australian margin study areas is characterised by large areas with numerous deeply incised canyons and areas with low-angle slumps and scarps mostly on the upper part of the slope. Other geomorphic features on the continental slope include short escarpments of local extent and small volcanic peaks over the Houtman Sub-basin part of the Perth margin. New bathymetry from the Cuvier Plateau has mapped large volcanic domes, some of them with terraces, ridges, a large previously unmapped valley and two large seamounts (newly named the Cuvier Seamount and the Wallaby seamount). See GA Record 2009/38 (Geocat# 69606) for further details on processing methods.
