This product is a rendered 3D model of one of the five ACT fossil emblem candidates, the graptolite Monograptus exiguus. The format of the file is ply. or Polygon File Format, and it is designed to store 3D data. The model requires no post-scanning manipulation as it is already complete. The purpose of this is to make this file format publicly available to local school communities so they can 3D print the fossil emblems themselves and engage students with Earth science related topics. <b>Acknowledgement:</b> Computed Tomography (CT) Scans and models generated at <a href="https://ctlab.anu.edu.au/">CTLab</a> - National Laboratory for X-Ray Micro Computed Tomography, Research School of Physics, The Australian National University (ANU), Canberra.

X3D Model and Visualisation of the Hydrostratigraphic System in the Hodgson and Kings Creek Sub-Catchments

<div>This model is a volumetric representation of receiver function analysis based on common conversion point (CCP) profiles created every 50 km in North-South and East-West directions below the AusArray network (Gorbatov et al., 2020), combining them into one 3D image. The model bounds are: (-21.74, 132.52) - (-17.30, 141.46), geographic projection EPSG:28353. The model file is distributed in ASCII GoCad stratigraphic grid format (SGrid) where units are longitude (meters), latitude (meters), depth (meters) and value of receiver function amplitude.</div><div><br></div><div>Geoscience Australia’s Exploring for the Future program provides precompetitive information to inform decision-making by government, community and industry on the sustainable development of Australia's mineral, energy and groundwater resources. By gathering, analysing and interpreting new and existing precompetitive geoscience data and knowledge, we are building a national picture of Australia’s geology and resource potential. This leads to a strong economy, resilient society and sustainable environment for the benefit of all Australians. This includes supporting Australia’s transition to a low emissions economy, strong resources and agriculture sectors, and economic opportunities and social benefits for Australia’s regional and remote communities. The Exploring for the Future program, which commenced in 2016, is an eight year, $225m investment by the Australian Government.</div>

It is with great interest that we read the paper by Mueller (2015) who proposes that the majority of small pockmarks with diameters less than about 10 m on the northwest shelf of Australia may be of biotic origin, created by the fish Epinephelus, the Grouper. This hypothesis is based on a spatial association between pockmarks and Epinephelus at a number of sites on the northwest shelf and elsewhere around Australia, and on recent work undertaken on the habitats and observed behaviours of grouper fish in the Gulf of Mexico who excavate sediment from pre-existing solution cavities (Coleman et al., 2010; Wall et al., 2011). However, we contend that critical details have not been taken into account as part of Mueller's (2015) hypothesis, and additional consideration of existing geologic, geomorphic, sedimentologic and geochemical information is required. To make the science more robust, here we present a more comprehensive overview of the information available.

The aim of this document is to: * outline the general process adopted by Geoscience Australia in modelling tsunami inundation for a range of projects conducted in collaboration with Australian and State Government emergency management agencies * allow discoverability of all data used to generate the products for the collaborative projects as well as internal activities.

This study brings together a wide range of datasets to provide a comprehensive assessment of the Pandurra Formation sedimentology and geochemistry in 3D. Sedimentology and geochemistry datasets generated this study are combined with pre-existing data to generate a 3D interpretation of the Pandurra Formation and improve understanding of how the Pandurra formation as we see it to today was deposited and subsequently post-depositionally mineralised.

The Galilee Basin Hydrogeological Model is a numerical groundwater flow model of the Galilee subregion in Queensland, an area of approximately 300,000 square kilometres. The model encompasses the entire geological Galilee Basin as well as parts of the overlying Eromanga Basin and surficial Cenozoic sediments. The model includes aquifers that form part of the Great Artesian Basin (specifically those aquifers in the Eromanga Basin), a hydrogeological system of national significance (see Evans et al 2018). The development of the Galilee Basin Hydrogeological Model represented an ambitious, first-pass attempt to better understand potential regional-scale cumulative groundwater impacts of seven proposed coal mines in the Galilee Basin (as known circa 2014, see Lewis et al. 2014 for details). This work was commissioned as part of the bioregional assessment for the Galilee subregion (https://www.bioregionalassessments.gov.au/assessments/galilee-subregion). Geoscience Australia has made the flow model and associated datasets available to support further academic or research investigations within the region. Importantly though, due to a number of limitations and assumptions (outlined in the final model report, Turvey et al., 2015), the model is not suitable for decision-making in relation to water resource planning or management. Further, the model was not developed to predict potential groundwater impacts of any individual mining operations, but provides a regional cumulative development perspective. The groundwater model and associated report were produced by HydroSimulations under short-term contract to Geoscience Australia in 2015. The report is referenced in several products released as part of the bioregional assessment (BA) for the Galilee subregion. However, due to the size, complexity and limitations of this model, this model was not used as the primary groundwater modelling input for the Galilee BA. Further detail about the key modelling limitations and why it was unsuitable for use in the Galilee BA are outlined in the BA Groundwater modelling report (Peeters et al., 2018).
