<div>The Abbot Point to Hydrographers Passage bathymetry survey was acquired for the Australian Hydrographic Office (AHO) onboard the RV Escape during the period 6 Oct 2020 – 16 Mar 2021. This was a contracted survey conducted for the Australian Hydrographic Office by iXblue Pty Ltd as part of the Hydroscheme Industry Partnership Program. The survey area encompases a section of Two-Way Route from Abbot Point through Hydrographers Passage QLD. Bathymetry data was acquired using a Kongsberg EM 2040, and processed using QPS QINSy. The dataset was then exported as a 30m resolution, 32 bit floating point GeoTIFF grid of the survey area.</div><div>This dataset is not to be used for navigational purposes.</div>

The Historical Bushfire Boundaries service represents the aggregation of jurisdictional supplied burnt areas polygons stemming from the early 1900's through to 2022 (excluding the Northern Territory). The burnt area data represents curated jurisdictional owned polygons of both bushfires and prescribed (planned) burns. To ensure the dataset adhered to the nationally approved and agreed data dictionary for fire history Geoscience Australia had to modify some of the attributes presented. The information provided within this service is reflective only of data supplied by participating authoritative agencies and may or may not represent all fire history within a state.

<div>The A1 poster incorporates 4 images of Australia taken from space by Earth observing satellites. The accompanying text briefly introduces sensors and the bands within the electromagnetic spectrum. The images include examples of both true and false colour and the diverse range of applications of satellite images such as tracking visible changes to the Earth’s surface like crop growth, bushfires, coastal changes and floods. Scientists, land and emergency managers use satellite images to analyse vegetation, surface water or human activities as well as evaluate natural&nbsp;hazards.</div>

All commercially produced hydrogen worldwide is presently stored in salt caverns. The only known thick salt accumulations in eastern Australia are found in the Boree Salt of the Adavale Basin in central Queensland. The Boree Salt consists predominantly of halite and is considered to be suitable for hydrogen storage. In 2021, Geoscience Australia contracted Intrepid Geophysics to perform 3D geological modelling of the Adavale Basin, particularly interested in modelling the Boree Salt deposit in the region. The developed 3D model has identified three main salt bodies of substantial thicknesses (up to 555 m) that may be suitable for salt cavern construction and hydrogen storage. These are the only known salt bodies in eastern Australia and represent potentially strategic assets for underground hydrogen storage. However, there are still unknowns with further work and data acquisition required to fully assess the suitability of these salt bodies for hydrogen storage. Geoscience Australia has transformed Intrepid Geophysics' Adavale Basin 3D Modelling dataset into Petrel. This Petrel dataset is part of Geoscience Australia's Exploring for the Future program. Files including a readme file and Petrel dataset that consists of formation surfaces, faults, borehole information and formation tops.

This resource includes bathymetry data acquired during the Keppel Bay 2004 bathymetry survey. Data were collected using a Reson SeaBat 8125 multibeam sonar system by Curtin University of Technology (CUT), Defence Science and Technology Organisation (DSTO) and Geoscience Australia (GA) on the charter vessel Rum Rambler during the period 20th – 26th September 2004. The survey was undertaken as a collaborative project between CUT, DSTO and GA under the Coastal Water Habitat Mapping (CWHM) Project within Coastal Cooperative Research Centre Program. The purpose of the project was to build baseline information for benthic habitats within the study area. This V1 dataset contains a 1m resolution 32-bit floating point geotiff file of the bathmetry of target areas in Keppel Bay, derived from the processed Reson SeaBat 8125 bathymetry data, using CARIS HIPS and SIPS software. This dataset is not to be used for navigational purposes. This dataset is published with the permission of the CEO, Geoscience Australia.

Digital Earth Australia (DEA) is a key piece of public data infrastructure that uses images and information recorded by satellites orbiting our planet to detect physical changes across Australia in unprecedented detail. Landsat 5, 7 and 8 ‘analysis-ready’ data are currently available within DEA, where the raw satellite data have been corrected and orthorectified to enable easy interrogation of data across sensors. Geoscience Australia is developing techniques for analysing the data within DEA to identify wetlands and groundwater dependent ecosystems across northern Australia. These techniques include summarising observations of ‘wetness’ acquired over 30 years and linking these observations to gridded rainfall measurements to identity waterbodies and wetlands that persist during periods of low rainfall. These wetness summaries have been shown to correspond with known spring complexes in the Carmichael River catchment in Queensland, and have been used to improve the understanding of groundwater discharge processes within basalt provinces in the Upper Burdekin region in Queensland.

This Record presents data collected between March and September 2018 as part of the ongoing Northern Territory Geological Survey–Geoscience Australia (NTGS–GA) SHRIMP geochronology project under the National Collaborative Framework (NCF) agreement and Geoscience Australia's Exploring for the Future Programme. Five new U–Pb SHRIMP zircon geochronological results derived from five samples of meta-igneous and metasedimentary rocks from MOUNT RENNIE (southwestern Aileron Province and northwestern Warumpi Province) in the Northern Territory are presented herein. All five samples are located at or close to the recently discovered greenfield Grapple and Bumblebee prospects that contain precious and base metal sulfide mineralisation. This Record represents the first attempt to provide temporal constraints on the country rocks that host or occur close to this mineralisation. <b>Bibliographic Reference:</b> Kositcin N, McGloin MV, Reno BL and Beyer EE, 2019.
