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.

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.
