This resource includes bathymetry data acquired during the Submarine Cape Range Canyons bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. The Seamounts, Canyons and Reefs of the Coral Sea bathymetry survey was led by Dr. Rachel Przeslawski (Geoscience Australia) with a team of scientists from Geoscience Australia, Curtin University, Western Australian Museum and Scripps Institution of Oceanography aboard the Schmidt Ocean Institute (SOI) RV Falkor from the 8th of March to the 8th of April 2020. The primary objective of this survey was to map unexplored submarine canyons in the Gascoyne Marine Park. Submarine canyons are crucial habitats for a variety of biota and understanding their geometry, depth and species diversity is underpinned by high resolution bathymetry data. The bathymetry data collected in this survey can assist with scientific research, marine park management and understanding Australia’s marine estate. This dataset contains a 64m and a 16m, for water depths shallower than 2560m resolution 32-bit geotiff of the Cape Range and Cloates Canyons area produced from the processed EM302 and EM710 bathymetry data combined. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

This resource includes bathymetry data acquired during the Visioning the Coral Sea Marine Park bathymetry survey using Kongsberg EM302 and EM710 multibeam sonar systems. Visioning the Coral Sea Marine Park bathymetry survey (FK200429/GA4861) was led by Dr. Rob Beaman (James Cook University) and a team of scientists from Geoscience Australia, The University of Sydney, and the Queensland Museum, aboard the Schmidt Ocean Institute’s research vessel Falkor, from the 29th of April to 11th of June 2020. The primary objective of the survey was to map in detail the Queensland Plateau, including the steeper reef flanks and target the enigmatic seabed features, like the numerous drowned reef pinnacles and long meandering channels on the plateau surface. The second objective of this survey was to investigate the extent of the bleaching on the mesophotic or deeper reef, and if these reefs could act as a potential refuge for the Great Barrier Reef. The survey also aimed at providing insights into the geological evolution and biodiversity of Australia’s marine frontier. This dataset is not to be used for navigational purposes.
