The Otway, Gippsland Basins and Bass Strait 3D seismic derived bathymetry compilation (20220007C) was produced by the University of Western Australia, Norwegian Geotechnical Institute and UniLasalle in collaboration with Geoscience Australia through the AusSeabed initiative. The compilation integrates 87 bathymetry grids derived from available and workable 3D seismic datasets into a 30 m resolution 32-bit GeoTIFF, including both reflection and navigation derived data. A detailed workflow is described in: Lebrec, U., Paumard, V., O'Leary, M. J., and Lang, S. C., 2021, Towards a regional high-resolution bathymetry of the North West Shelf of Australia based on Sentinel-2 satellite images, 3D seismic surveys, and historical datasets: Earth System Science Data, v. 13, no. 11, p. 5191-5212 https://doi.org/10.5194/essd-13-5191-2021, 2021.
