This flythrough illustrates the geomorphic features imaged during a multibeam sonar survey (GA-0348) of the coastal waters around Casey station and the adjacent Windmill Islands. The survey utilised GA’s Kongsberg EM3002D multibeam echosounder, motion reference unit and C-Nav differential GPS system mounted on the Australian Antarctic Division’s (AAD) science workboat the Howard Burton. The survey was a collaborative project between GA, the AAD and the Royal Australian Navy (RAN). During the survey a total of ~27.3 km2 of multibeam bathymetry, backscatter and water-column data were collected. The new high-resolution bathymetric grid (1 m resolution) reveals seafloor features in the Casey area in unprecedented detail.
