The Peterborough to Port Fairy bathymetry survey was acquired by Deakin University Marine Mapping lab onboard the M/V Yolla during the period 28 May 2018 - 19 June 2018 using a Kongsberg EM2040C multibeam sonar system. The survey was completed as part of the Victorian Coastal Monitoring Program, which requires bathymetry data to understand offshore sediment dynamics within Victorian coastal waters. This dataset contains a 2m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the study area, derived from the processed EM2040C bathymetry data using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes.

The Vanderford Glacier bathymetry survey was acquired by the Australian Antarctic Division (AAD) during the maiden Antarctic voyage of the RSV Nuyina from 23 December 2021 – 30 January 2022. The survey area encompasses Vincennes Bay (offshore Vanderford Glacier), and offshore Casey Station and Davis Station and was completed as a combination of commissioning trials, ice trials and a resupply voyage. Bathymetry data was acquired using a Kongsberg EM 712 and EM 122 and processed using QPS Qimera and Caris HIPS and SIPS. The dataset was then exported to GeoTIFF using CARIS HIPS and SIPS software. This dataset contains nine 5m-, 10m-, 16m-, 20m-, 64m-, 128m-resolution 32-bit floating point GeoTIFF files. This dataset is not to be used for navigational purposes.

​The King Island North, Bass Strait, bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the M/V Pacific Quest during the period 28 January to 6 May 2021. This was a contracted survey conducted as part of the HydroScheme Industry Partnership Program (HIPP). The survey area encompasses a region located north of King Island in Bass Strait, including the approaches to Phoques Bay, located at the NW extremity of King Island. Bathymetry data was acquired using a Kongsberg EM2040D and processed using QPS Qimera V2.0.1. The dataset was then exported to GeoTIFF using CARIS HIPS and SIPS software. This dataset contains a 30m-resolution 32-bit floating point GeoTIFF file of the bathymetry in the survey area. This dataset is not to be used for navigational purposes.

Geoscience Australia conducted a marine survey to provide seabed environmental information to support the assessment of the CO2 storage potential of the Vlaming Sub-Basin. The survey was undertaken under the Australian Government's National CO2 Infrastructure Plan (NCIP) to help identify sites suitable for the long term storage of CO2. The major aim of this survey was to look for evidence of any gas fluid seepage at the seabed and wether the location had faults that have been identified in a number of seismic lines. The survey also mapped seabed biota in the area of interest to indentify any biota communities that are related with seepage. This research addresses key questions of the regional seal integrity of the Southern Perth Shale and the potential for storing of CO2 in the Early Cretaceous Gage Sandstone. The survey was conducted by Fugro's Southern Supporter in the Vlaming Sub-Basin, North and South of Rotnest Island between the period of the 17th of March to the 20th of April 2012. Shallow seismic sub bottom profiler data were acquired as well as high resolution multibeam bathymetry and backscatter data during the survey.

A bathymetric survey of Darwin Harbour was undertaken during the period 24 June to 20 August 2011 by iXSurvey Australia Pty Ltd for the Department of Natural Resources, Environment, The Arts and Sport (NRETAS) in collaboration with Geoscience Australia (GA), the Darwin Port Corporation (DPC) and the Australian Institute of Marine Science (AIMS) using GA's Kongsberg EM3002D multibeam sonar system and DPC's vessel 'Matthew Flinders'.

The Davis Coastal Seabed Mapping Survey, Antarctica (GA-4301 / AAS2201 / HI468) was acquired by the Australian Antarctic Division workboat Howard Burton during February-March 2010 as a component of Australian Antarctic Science (AAS) Project 2201 - Natural Variability and Human Induced Change on Antarctic Nearshore Marine Benthic Communities. The survey was undertaken as a collaboration between Geoscience Australia, the Australian Antarctic Division and the Australian Hydrographic Service (Royal Australian Navy). The objectives were to provide multibeam bathymetry and backscatter of the coastal region of the Vestfold Hills around Davis Station, Antarctica, to aid the understanding of sea bed character, benthic habitats, provide a basis for hydrodynamic modelling of water movement around Davis, and to update and extend the navigational charts of the region.

This resource contains bathymetry data for Outer Darwin Harbour collected by Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Northern Territory Government (Department of Land Resource Management) during the period from 28 May and 23 June 2015 on the RV Solander (survey SOL6187/GA0351). This project was made possible through offset funds provided by INPEX-led Ichthys LNG Project to Northern Territory Government Department of Land Resource Management, and co-investment from Geoscience Australia and Australian Institute of Marine Science. The intent of this four year (2014-2018) program 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 (bathymetry) data for outer Darwin Harbour, including Shoal Bay; 2. Characterise substrates (acoustic backscatter properties, grainsize, sediment chemistry) for outer Darwin Harbour, including Shoal Bay; 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, underwater photography and video of grab sample locations and oceanographic information including tidal data and sound velocity profiles. This dataset comprises multibeam bathymetry surface grid.

This is a compilation of bathymetry surveys GA-4415 and GA-0348. GA-4415 survey was conducted by the Royal Australian Navy (RAN) and the Australian Antarctic Division (AAD) onboard the RAN vessel Wyatt Earp in 2013/2014, while GA-0348 survey was a collaboration between Geoscience Australia (GA) , the Royal Australian Navy and Australian Antarctic Division acquired by the AAD workboat Howard Burton during December 2014 to February 2015. The survey goal was to acquire high resolution bathymetry data to improve our understanding of the seafloor using multibeam sonar. The bathymetry data collection will be supplemented by physical sampling of the seafloor sediments and video recordings of the biological communities living in the seafloor. The survey covers areas that are frequently used by the RSV Aurora Australis. Improving our understanding of the seabed environment in these shallow coastal waters will ultimately lead to a better environmental management of the Australian Antarctic Territory. The data will also help the RAN to develop more accurate navigation charts therefore reducing the risk to maritime operation in the region. This dataset is not to be used for navigational purposes.
