This is a compilation of bathymetry surveys GA-4415 and GA-0348. GA-4415 survey was conducted by the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) onboard the RAN vessel Wyatt Earp in 2013/2014, while GA-0348 survey was a collaboration between Geoscience Australia (GA) , the Royal Australian Navy and Australian Antarctic Division acquired by the AAD workboat Howard Burton during December 2014 to February 2015. The survey goal was to acquire high resolution bathymetry data to improve our understanding of the seafloor using multibeam sonar. The bathymetry data collection will be supplemented by physical sampling of the seafloor sediments and video recordings of the biological communities living in the seafloor. The survey covers areas that are frequently used by the RSV Aurora Australis. Improving our understanding of the seabed environment in these shallow coastal waters will ultimately lead to a better environmental management of the Australian Antarctic Territory. The data will also help the RAN to develop more accurate navigation charts therefore reducing the risk to maritime operation in the region.
