The Southeast Tasmania and Southern Macquarie Ridge Bathymetry dataset was acquired by the Australian Geological Survey Organisation (AGSO) (Geoscience Australia predecessor) during the AUSTREA-2 marine survey undertaken from 15 January - 9 February 2000 onboard the French Oceanographic and Geoscience Research Vessel N/O L'Atalante using a Simrad EM12D multibeam sonar system. The survey was completed as part of the work to map the foot-of-slope position to support definition of Australia's legal Continental Shelf under the United Nations Convention on the Law of the Sea. This dataset contains 120m-, 160m-, 250m-, 280m-, 300m-, 360m- and 440m-resolution 32-bit floating point GeoTIFF files of the bathymetry in the survey area, derived from the processed EM12D bathymetry data, using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes.
