Tasmanian East Coast (GA4883)
This resource includes bathymetry data acquired during the Tasmanian East Coast bathymetry survey collected by Institute for Marine and Antarctic Studies (IMAS) University of Tasmania (UTAS) during the period 12 – 23 April 2021 on the RV Abyss using a Kongsberg Maritime EM2040C multibeam sonar (contracted from CSIRO). 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. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

While AusSeabed aims to publish data based on the requirements stated in the AusSeabed multibeam guidelines (version 1, https://australian-multibeam-guidelines.github.io), we will also publish interim products (version 0) that are currently available, but have not yet been standardised (version 1). Users should be aware that V1 products will always supersede V0 products. This dataset was produced using CARIS HIPS & SIPS and the AusSeabed-recommended processing methodology as follows.
1. A new Caris project was created in conjunction with existing or newly created vessel configuration file(s).
2. The raw swath sonar data files were imported to the project. GGK is the preferred navigation and ellipsoid height source.
3. GPS tide was applied and all data were georeferenced (merged) to EGM2008 vertical datum.
4. Swath Angle surfaces at 0.5m resolution were generated for reference during data cleaning.
5. The outer beams (beams 1-9 and 246-256) were removed due to excessive noise.
6. Data were further manually cleaned using a combination of swath and subset editing.
7. The final processed grids were exported as seven 32-bit floating point Geotiffs at 0.5m resolution, referenced to EGM2008.
