This report presents a summary of the groundwater and surface water hydrochemistry data release from the Howard East project conducted as part of Exploring for the Future (EFTF) —an eight year, $225 million Australian Government funded geoscience data and information acquisition program focused on better understanding the potential mineral, energy and groundwater resources across Australia. This data release records the groundwater and surface water sample collection methods and hydrochemistry and isotope data from monitoring bores in the Howard East project area, Northern Territory (NT). The Howard East project is a collaborative study between Geoscience Australia and the NT Government. Hydrochemistry and isotope data were collected from existing bores in the Howard East area. The sampling methods, quality assurance/quality control procedures, analytical methods and results are included in this report and all hydrochemistry data are available for download from the link at right.

The National Hazard Impact Risk Service for Tropical Cyclone Event Impact provides information on the potential impact to residential separate houses due to severe winds. The information is derived from Bureau of Meteorology tropical cyclone forecast tracks, in combination with building location and attributes from the National Exposure Information System and vulnerability models to define the level of impact. Impact data is aggregated to Statistical Area Level 1, categorised into five qualitative levels of impact.

This resource includes backscatter data for Arafura Marine Park (Arafura Sea) collected by Geoscience Australia (GA) and the Australian Institute of Marine Science during the period 2 – 15 November 2020 on the RV Solander. The survey was undertaken as a collaborative project funded through the National Environmental Science Program Marine Biodiversity Hub, with co-investment by GA and AIMS. The purpose of the project was to build baseline information for benthic habitats in Arafura Marine Park that will support ongoing environmental monitoring within the North Marine Park Network as part of the 10-year management plan (2018-2028). Data acquisition for the project included multibeam bathymetry and backscatter for two areas (Money Shoal and Pillar Bank), seabed samples and underwater imagery of benthic communities and demersal fish. This backscatter dataset contains two 32-bit geotiff files of the backscatter mosaic for two survey areas produced from the processed EM2040C Dual Head system using the CMST-GA MB Process v15.04.04.0 (x64) toolbox software co-developed by the Centre for Marine Science and Technology at Curtin University and Geoscience Australia. A detailed report on the survey is provided in: Picard, K. Stowar, M., Roberts, N., Siwabessy, J., Abdul Wahab, M.A., Galaiduk, R., Miller, K., Nichol, S. 2021.

This dataset provides the locations and status, as at 30 June 2020, of Australian operating mines, mines under development, mines on care and maintenance and resource deposits associated with critical minerals. Developing mines are deposits where the project has a positive feasibility study, development has commenced or all approvals have been received. Mines under care and maintenance and resource deposits are based on known resource estimations and may produce critical minerals in the future.

These videos are recordings of online secondary teacher professional learning sessions, delivered by Geoscience Australia’s Education Team. “Can I Fall Down the Cracks?” Plate Tectonic Misconceptions Part 1 This session focused on common misconceptions that are encountered when teaching plate tectonics. The student misconceptions addressed are: 1. We can’t see the tectonic plates (starting at 5:35) 2. The mantle is made of liquid rock (starting at 11:25) 3. The plates move by convection in the mantle (starting at 17:35) 4. When plates collide one always goes under the other (starting at 22:15) 57 minutes total duration, with Q&A with an expert scientist starting at 34 minutes. “Can I Fall Down the Cracks?” Plate Tectonic Misconceptions Part 2 This session focused on common misconceptions that are encountered when teaching hazards associated with plate tectonics. The student misconceptions addressed are: 1. Earthquakes are measured using the Richter scale (starting at 3:15) 2. The magnitude of an earthquake depends on how far away it is (starting at 7:20) 3. Earthquakes can be predicted (starting at 10:52) This section includes a description of Raspberry Shake equipment: low cost earthquake monitoring for the classroom 4. There are no volcanoes in Australia (starting at 18:25) 5. You can surf a tsunami (starting at 24:17) 51 minutes total duration, with Q&A with an expert scientist starting at 37 minutes.

A dataset of potential geological sequestration sites has been compiled as part of the Australian Petroleum Cooperative Research Centre's GEODISC program. Sites have been identified across all Australian sedimentary basins.

Assessing the regional prospectivity of tight, shale and deep coal gas resources in the Cooper Basin is an integral component of the Australian Government’s Geological and Bioregional Assessment Program, which aims to encourage exploration and understand the potential impacts of resource development on water and the environment. The Permo-Triassic Cooper Basin is Australia’s premier onshore conventional hydrocarbon-producing province, yet is relatively underexplored for unconventional gas resources. A chance of success mapping workflow, using rapid integration of new and existing data, was developed to evaluate the regional distribution of key gas plays within the Gidgealpa Group. For each play type, key physical properties (e.g. lithology, formation depths and extents, source rock and reservoir characteristics, and rock mechanics) were identified and criteria were used to assign prospectivity rankings. Parameter maps for individual physical properties were classified, weighted and then combined into prospectivity confidence maps that represent each play’s relative chance of success. These combined maps show a high chance of success for tight, shale and deep coal gas plays in the Nappamerri, Patchawarra and Windorah troughs, largely consistent with exploration results to-date. The outputs of this regional screening process help identify additional areas warranting investigation, and may encourage further exploration investment in the basin. This methodology can be applied to other unconventional hydrocarbon plays in frontier and proven basins.
