Bathymetry grids of Tasmante Survey (GA-0125 AGSO Leg1 & 2)

The Tasmante bathymetry survey, GA-0125 was acquired by Geoscience Australia onboard the IFREMER N/O L'Atalante from the 12th of February to the 28th of March 1994 using a Simrad EM12 Dual sonar system.The objectives of the west Tasmanian swath-mapping cruise (Tasmante) are to: determine the structure of the continental margin off west Tasmania, on the South Tasman Rise, and on the adjacent abyssal plain; examine the relationships between lithospheric extension in continental crust, the orientation of the seafloor spreading phases, and the formation of the transform margin along west Tasmania and the South Tasman Rise; map sedimentary patterns and processes to build an understanding of Neogene changes in sedimentation and their relationship to tectonic and climatic.This dataset contains a 100m resolution 32-bit geotiff of the Tasmante 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.
