The Austrea1 bathymetry survey, GA-0222 was acquired by Geoscience Australia onboard the IFREMER N/O L'Atalante from the 17th of December 1999 to the 11th of January 2000 using a Simrad EM12 Dual sonar system. The main objectives of the shipboard program are to collect seabed and sub- bottom data in specific areas off southeast Australia for marine research (geological and biological), assessment of resource potential, regional marine zone planning and management, and to support Australia's claims under UNCLOS and to map the deep water part of a marine protected area in the Great Australian Bight (GAB). This dataset contains a 100m resolution 32-bit geotiff of the Austrea1 survey, produced from the processed EM12D bathymetry data of the survey area using the CARIS HIPS and SIPS software. This dataset is published with the permission of the CEO, Geoscience Australia. Not to be used for navigational purposes.
