Geoscience Australia conducted a hydrographic and seafloor characterisation survey nearshore from Davis Station in the Australian Antarctic Territory. The multibeam bathymetry data was acquired during January-February 2017 from the AAD workboat Howard Burton in the Vestfold Hills region. This survey is a component of the Australian Antarctic Program (AAP) and Project 5093 Hydrographic Surveying and Seafloor Characterisation Program (Chief Investigator: Ursula Harris, AAD). The objective of the survey was to map the seabed environment in shallow (<300 m) coastal waters for the compilation of nautical charts and acquire baseline data for environmental management, science, infrastructure and logistical operations. Data collected during the survey includes high-resolution multibeam bathymetry, backscatter, sediment samples, seafloor imagery and sub-bottom profiles. This dataset is a 32bit geotiff at 11 m resolution using EGM2008 vertical datum and EPSG:4326 coordinate system and produced from the processed ...
