This dataset is a compilation of photographic images taken of the National Mineral and Fossil Collection specimens

The Australian Resource Reviews are periodic national assessments of individual mineral commodities. The reviews include evaluations of short-term and long-term trends for each mineral resource, world rankings, production data, significant exploration results and an overview of mining industry developments.

<p>This dataset contains magnetotelluric data and a 3D inversion model from the 09GA-GA1 deep magnetotelluric transect, collected in Central Australia in 2009. The transect is 350 km long, with data acquired from 18 stations with both broadband and long period instrumentation, and 21 stations with broadband instrumentation only (a total of 39 sites). The resulting station spacing is 10km for the broadband stations, and 20km for stations with both broadband and long period instrumentation. We have reprocessed the broadband data using the Bounded Influence, Remote Reference Processing software (BIRRP), yielding an extended bandwidth of 0.003 to 1300 s and merged these data with the long period data. We have inverted the data using the ModEM 3D inversion code. <p>More details on the data processing, analysis, modelling, and interpretation can be found in the following paper: Kirkby, A. and Duan, J., 2019.

Benthic sediment sampling of Inner Darwin Harbour (GA0358) and shallow water areas in and around Bynoe Harbour (GA0359) was undertaken between May 29 and June 19, 2017. Partners involved in the surveys included Geoscience Australia (GA), the Australian Institute of Marine Science (AIMS) and the Department of Environment and Natural Resources within the Northern Territory Government (NT DENR) (formerly the Department of Land and Resource Management (DLRM)). These surveys form part of a four year (2014-2018) science program aimed at improving knowledge about the marine environments in the regions around Darwin and Bynoe Harbour’s through the collection and collation of baseline data that will enable the creation of thematic habitat maps to underpin marine resource management decisions. This project is being led by the Northern Territory Government and is supported by the INPEX-led Ichthys LNG Project, in collaboration with - and co-investment from GA and AIMS. This dataset comprises total sediment metabolism, carbonate, organic isotope and organic and inorganic element measurements on seabed sediments.

The earthquake impact scenario outlined in this Professional Opinion was initially developed to support the Australian Vulnerability Profile (AVP) Project. The project is led by Emergency Management Australia and aims to better articulate what makes Australia vulnerable to disaster when severe-to-catastrophic natural hazards impact what Australians value. The Profile will narrate at the national level Australia’s vulnerabilities and contribute to a better understanding of where to target mitigation, develop policy and direct efforts to improve resilience. As part of the project, a number of workshops have been held with stakeholders to foster discussion amongst key government and non-government stakeholder groups and academic disciplines to inform how we strategically prepare for long-term resilience and how we can reduce and manage systematic risks. A scenario modelling a magnitude 6.5 earthquake near the Adelaide business district was developed by Geoscience Australia (GA) for use at the AVP stakeholder workshop, held in Adelaide on 23-24 November 2016. The South Australian Fire and Emergency Services Commission (SAFECOM) has subsequently made a request to use this scenario for further detailed state-based planning initiatives. This report is being prepared to support these initiatives and provide the necessary background for future reference. This report provides the: • background to why this earthquake scenario was selected; • the geological and geophysical context in which it is placed; • the historical seismicity for the area; and • a qualitative description of the estimated impact to the Adelaide region. Key assumptions and limitations in the approach are summarised below: • A rare earthquake event was selected given the premise of the AVP project (i.e. severe-to-catastrophic event). • The event was modelled using GA’s Earthquake Risk Model (EQRM). • An Exposure Report is provided based on GA’s National Exposure Information System (NEXIS). • A qualitative assessment of impact is outlined based on the estimated level of earthquake ground shaking. In summary, this potential impact could be commensurate with that experienced in Christchurch from the magnitude 6.3 22 February 2011 earthquake.

This document details the methods and results of the project Adelaide LiDAR Classification and Derived Products¿ performed by RPS for Geoscience Australia in 2013. Lineage and Accuracy Statements for ANZLIC metadata documents for each of the project deliverables are included. Airborne LiDAR data was acquired over Adelaide in September 2008 and North Adelaide in September 2011. Differences in the level of classification reduced the ability to integrate the data into an accurate, seamless and consistent coastal DEM suitable for detailed modelling the potential impacts of coastal inundation or riverine flooding. The objective of this project was to reclassify both the 2008 and 2011 point clouds to ICSM Level 3 and derive hydro flattened 1m bare earth DEMs and; 0.25m cartographic contours, all inline with the ICSM LiDAR Acquisition Specifications. Figure 1. Adelaide LiDAR Reclassification 2012 overview map The LiDAR The LiDAR was provided as tiled LAS files. RPS did not apply any vertical or horizontal adjustments to the LiDAR and is unable to comment on the spatial accuracy of the point cloud. The deliverables were: Classified ICSM Level 2 and Level 3 point clouds in LAS format 1 metre DEMs in ESRI Binary grid format 0.25 metre contours in ESRI Shape format Break lines in ESRI Shape format. This report All files were named according to the ICSM file naming specifications.
