Abstract
The Casey shallow-water near-shore seabed mapping survey (survey number GA-0348) was conducted as collaboration between Geoscience Australia (GA, Department of Science and Industry), the Royal Australian Navy (RAN, Department of Defence) and the Australian Antarctic Division (AAD, Department of the Environment). The survey was conducted as part of the ongoing AAD program Hydrographic Surveying and Bathymetric Data Acquisition (AAD 3326) and complements a previous charting survey to the Casey region undertaken by RAN and AAD (using the RAN vessel ASV Wyatt Earp) in 2013/14 (also conducted under AAD 3326). The purpose of the survey was to acquire geophysical, geological and biological data from the seabed environment in the shallow (<250 m) coastal waters adjacent to Casey station. The survey acquisition phase formed the main work program for the Antarctic Geoscience Program and Advice activity as part of the Marine Biodiversity and Antarctic Geoscience (MBAG) Section at Geoscience Australia during 2014/15. The shallow water marine environment around Casey station, East Antarctica, is a high use area in the Australian Antarctic Territory, and is frequently visited by the RSV Aurora Australis and smaller vessels conducting scientific research in the area, yet bathymetry data in the area is limited. Additionally, a long-term dive program has revealed the marine habitats in the area host globally significant levels of biodiversity, but this knowledge is geographically restricted in scope (i.e. shallow depths, close to shore). This biodiversity faces pressures from human activities and climate change, yet extensive knowledge gaps remain, limiting efforts to conserve and manage it effectively.

The survey was conducted as part of the ongoing AAD program Hydrographic Surveying and Bathymetric Data Acquisition (AAD 3326) and complements a previous charting survey to the Casey region undertaken by RAN and AAD (using the RAN vessel ASV Wyatt Earp) in 2013/14 (also conducted under AAD 3326). Bathymetric data was acquired using Geoscience Australia¿s dual head Kongsberg EM3002D multibeam sonar system. The survey was conducted on the Australian Antarctic Division workboat Research Vessel (RV) Howard Burton. 110.0 111.0 -66.5 -66.0
