The Tasmanian East Coast bathymetry survey was led by Dr. Vanessa Lucieer (IMAS). The purpose of the project was to map the fine-scale spatial distribution of key abalone habitat impacted by urchins in < 25 m water depth using multibeam acoustic imagery. This dataset contains seven 0.5m-resolution 32-bit floating point geotiff files of the bathymetry in study area and transits, derived from the processed EM2040C bathymetry data, using CARIS HIPS and SIPS software. A detailed report on the survey is provided in: Lucieer V, Keane J, Shelamoff V, Nau A, Ling S, Mapping abalone habitat impacted by Centrostephanus on the east coast of Tasmania: Final contracted report for the Abalone Industry Reinvestment Fund (AIRF Project 2021) and Tasmanian Climate Change Office (Climate Research Grants Program 2021), Institute for Marine and Antarctic Studies, UTAS, December (2021) [Contract Report] http://ecite.utas.edu.au/148298.
