Brief description

The South-west Corner and Perth Canyon Marine Parks Bathymetry Acquisition was acquired by the Minderoo-UWA Deep-Sea Research Centre of the University of Western Australia on-board the MV Pangaea Ocean Explorer from the 24th of March to the 05th of April 2022, using a Kongsberg EM304 multibeam sonar.
The survey was led by Dr. Todd Bond and the collected data were processed by Dr. Yakup Niyazi.
This dataset contains a 64m-resolution and four 128m-resolution 32-bit floating point GeoTIFF files of the bathymetry in the study area, derived from the processed EM304 bathymetry data, using QPS Qimera v.2.5 software. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.
