A seafloor survey of Davis Harbour and surrounding coastal areas in Antarctica was carried out by Geoscience Australia (GA) between January and March 2010. The survey was conducted using a Konsberg-Simrad EM 3002 multibeam echo sounder (MBES). Processing and analysis of the bathymetry data was carried out by GA. This is a separate desktop study that used CARIS HIPS and SIPS version 7.1 software to process and analyse the acoustic backscatter data collected by the MBES to characterise the seafloor substrate. This paper presents preliminary results of the seafloor backscatter map and the outputs of the Angular Range Analysis model implemented in CARIS.
