This dataset contains the processed bathymetric dataset from the Lord Howe and Lord How Island survey area held by Geoscience Australia. This dataset includes multibeam echosounder data and was gridded at 50m resolution of the Lord Howe survey area and a 10m resolution of Lord Howe Island, based on the optimal resolution for the depth range encountered. The objective of the survey on the Lord Howe Island shelf (NSW) in 2008 (SS062008) was to map seabed bathymetry and characterise benthic environments through co-located sampling of surface sediments and infauna, rock coring, observation of benthic habitats using underwater towed video, and measurement of ocean tides and wavegenerated currents. Subbottom profile data was also collected to map sediment thickness and shelf stratigraphy. Data and samples were acquired using the National Facility Research Vessel Southern Surveyor.

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 resource includes bathymetry data acquired during the Seamounts, Canyons and Reefs of the Coral Sea 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. Brendan Brooke and Dr. Scott Nichol (Geoscience Australia) with a team of scientists from Geoscience Australia, James Cook University, The University of Sydney, University of Tasmania, University of Wollongong, Queensland Museum and Parks Australia aboard the Schmidt Ocean Institute (SOI) RV Falkor from the 2nd to the 30th of August 2020. The primary objective of the survey to collect and analyze geological and biological data of the outer, deep-water edge of the Great Barrier Reef and platform reefs in the adjacent Coral Sea Marine Park. R/V Falkor’s multibeam systems were used to map the structure of the reefs, canyons, and seamounts, illuminating their formative processes. The datasets acquired will greatly improve understanding of the sedimentary processes that influence biodiversity patterns, including how canyons and platform reefs may provide a pathway for sediment to travel from coastal and shelf water to deep filter feeders. The deep and irregular canyon and platform-reef topography likely leads to direct upwelling of nutrient-rich deep waters. This dataset contains a 64m and a 16m, for water depths shallower than 2560m, resolution 32-bit geotiff of the Seamounts, Canyons and Reefs of the Coral Sea survey area produced from the processed EM302 and EM710 bathymetry data combined.

This resource contains multibeam bathymetry data collected as part of the Darwin and Bynoe Harbour Habitat Mapping Project undertaken by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Environment and Natural Resources). The data were acquired during the period from 3 to 27 May 2016 on the RV Solander (survey SOL6432/GA04452). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Environment and Natural Resources, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) project is to improve knowledge of the marine environments in the Darwin and Bynoe Harbour regions by collating and collecting baseline data that enable the creation of thematic habitat maps that underpin marine resource management decisions. The specific objectives of the survey were to: 1. Obtain high-resolution geophysical (multibeam bathymetry) data for Bynoe Harbour; 2. Characterise seabed substrates (multibeam acoustic backscatter properties, seabed sediment grainsize, sediment chemistry) for Bynoe Harbour; and 3. Collect tidal data for the survey area. Data acquired during the survey included: multibeam sonar bathymetry and acoustic backscatter; physical samples of seabed sediments, seabed still images and video footage of grab sample locations, and oceanographic information including tidal data and water column sound velocity profiles.

The remote Eastern frontiers project aimed to provide a geological and petroleum prospectivity assessement of the Faust Capel Basins. Funded through Australian Governement Initiatives (Energy Security Program). The Faust Capel Basins survey GA-2436/ TAN0713 was acquired by Geoscience Australia onboard the RV Tangaroa (operated by NIWA) from the 6th of October to the 22nd of November 2007. The geographic range stretched from Wellington to the Faust Capel Basins to Lord Howe Island and back to Wellington. Approximately 8,945 sailing km of multibeam bathymetry was acquired. The high resolution bathymetry data imaged seafloor features in unprecedented detail, revealing the effects of recent magmatic activity and fluid migration on the seafloor. It also produced a new image of a flat topped unexplored seamount. A member of the Lord Howe Rise seamount chain.<p><p>This dataset is not to be used for navigational purposes.
