  • Hydrogeological assessment of the Maryborough Basin, submitted as an abstract for the 2013 IAH Congress.

  • Coastal aquifers are vulnerable to seawater intrusion, which is a significant issue in Australia. Geoscience Australia and the Nation Centre of Groundwater Research and Training undertook an assessment of Australia's vulnerability to seawater intrusion. The assessment utilised multiple approaches, including a vulnerability factor analysis; typological analysis; mathematical analysis; qualitative and quantitative analysis; and future land surface inundation and population growth analysis. This is presented as an abstract for the 2013 IAH Congress.

  • The Great Artesian Basin Water Resource Assessment involves a basin-scale investigation of water resources to fill knowledge gaps about the status of water resources in the basin and the potential impacts of climate change and resource development. This report addresses findings in the Carpentaria region. Citation: Smerdon BD, Welsh WD and Ransley TR (eds) (2012) Water resource assessment for the Carpentaria region.

  • The Officer Basin in South Australia and Western Australia is the focus of a regional stratigraphic study being undertaken by the Exploring for the Future (EFTF) program, an Australian Government initiative dedicated to increasing investment in resource exploration in Australia. This data release provides new data and discusses the results from a new commissioned petrographic study of rock samples from five wells of the Officer Basin including: GSWA Vines 1, Yowalga 3, Birksgate 1, Giles 1, and Munta 1. Data includes petrography, XRD, thin section scans and photos, as well as petrographic summaries

  • This report was compiled and written to summarise the four-year Palaeovalley Groundwater Project which was led by Geoscience Australia from 2008 to 2012. This project was funded by the National Water Commission's Raising National Water Standards Program, and was supported through collaboration with jurisdictional governments in Western Australia, South Australia and the Northern Territory. The summary report was published under the National Water Commission's 'Waterlines' series. This document is supported by related publications such as the palaeovalley groundwater literature review, the WASANT Palaeovalley Map and associated datasets, and four stand-alone GA Records that outline the detailed work undertaken at several palaeovalley demonstration sites in WA, SA and the NT. Palaeovalley aquifers are relied upon in outback Australia by many groundwater users and help underpin the economic, social and environmental fabric of this vast region. ‘Water for Australia’s arid zone – Identifying and assessing Australia’s palaeovalley groundwater resources’ (the Palaeovalley Groundwater Project) investigated palaeovalleys across arid and semi-arid parts of Western Australia (WA), South Australia (SA) and the Northern Territory (NT). The project aimed to (a) generate new information about palaeovalley aquifers, (b) improve our understanding of palaeovalley groundwater resources, and (c) evaluate methods available to identify and assess these systems.

  • As part of the Exploring For the Future program 2022 showcase, Geoscience Australia (GA) in collaboration with the Australian Institute of Geoscientists held an Airborne Electromagnetics (AEM) workshop in Perth on 11th August 2022. The workshop comprised the following: - An introduction to GA's 20 km spaced continent-wide AusAEM program, by Karol Czarnota - How the Western Australia government has successfully used 20 km spaced AEM data, by Klaus Gessner - An introduction to AEM, surveying, and quality control given by Yusen Ley-Cooper - An introduction to inverse theory presented by Anandaroop Ray - Hands-on AEM modeling and inversion using HiQGA.jl by Anandaroop Ray - Integrating geophysics and geology in subsurface interpretation, by Sebastian Wong - Avoiding the 10 most common pitfalls in AEM interpretation according to Neil Symington YouTube video from the workshop, as well as data and code to follow along with the videos can be found on GA's GitHub at <a href=https://github.com/GeoscienceAustralia/HiQGA.jl/tree/workshop><u>this link.</u></a>

  • <p>A regional mapping program conducted by Geoscience Australia addressed stratigraphic and structural aspects of exploration risk within the Triassic succession of the Roebuck Basin and parts of the adjacent sub-basins (central North West Shelf, Figure 1). <p>Seismic horizons of regional significance were mapped using 2D and 3D seismic surveys. Seismic survey coverage is shown in Figure 1. 2D surveys include regional deep surveys such as AGSO s110, AGSO s120, and PGS New Dawn. 3D surveys include Admiral, Beagle, CNOOC, Curt, Lord, Naranco, Polly, Whitetail, and a 5 x 5 km extract (used with permission) from the TGS Capreolus MC3D. Synthetic seismograms (Nguyen et al., 2019) were used to tie seismic horizons to wells. <p>The mapped horizons are placed within a regional tectonostratigraphic framework by Abbott et al. (2019, their Figure 2). This data pack comprises seismic horizon grids and isochron grids generated from the TR10.0_SB (base Triassic), TR17.0_SB (Mid–Triassic), and J10.0_SB (top Triassic) seismic horizons (Figure 2). Fault maps compiled at the TR10.0 _SB and J10.0_SB are also included.
