This is a compilation of all the processed bathymetric datasets held by Geoscience Australia for the Otway Basin, extending from Cape Jaffa in South Australia to north-west Tasmania. This dataset includes multibeam echosounder and LIDAR data, and was gridded at two resolutions (50 and 128 m) based on optimal resolution for the depth range encountered. The objective of this Otway Basin bathymetry dataset is to increase our understanding of the seafloor geomorphology of the region and provide a primary input dataset for the creation of numerous subsurface geophysical products. These include inputs to calibrated gravity and magnetic data to provide new insights to geological morphology and processes, inputs to 2D and 3D seismic processing for better subsurface imaging, inputs to velocity modelling for better time to depth conversions, and inputs to depth of burial 3D models to understand how sedimentary basins have evolved over geological time. This dataset is published with the permission of the CEO, Geoscience Australia. Not to be used for navigational purposes.
