A two part Indigenous-led and produced Aboriginal cultural heritage awareness training video for Geoscience Australia staff. The video explores a number of topics from the perspective of Traditional Owners and Custodians. Topics covered include: What is Country, Lore and Kinship; the importance of listening, connecting to Country and the transference of knowledge; Aboriginal cultural heritage legislation and policy in Australia, native title and cultural heritage; the impact of past policies; and, working towards best practice. The video complements Geoscience Australia's Land Access and Cultural Heritage Policy, Procedures and Best Practice Standards.

This short film promotes Geoscience Australia's online and publicly accessible hydrogen data products. The film steps through the functionality of GA's Australian Hydrogen Opportunities Tool (AusH2), and describes the upcoming Hydrogen Economic Fairways Tool which has been created through a collaborative effort with Monash University.

Australian Rainfall and Runoff (ARR) is a national guideline document, data and software suite that can be used for the estimation of design flood characteristics in Australia. This is the 4th edition of ARR, after the 1st edition was released by Engineers Australia in 1958. This edition is published and supported by the Commonwealth of Australia. Geoscience Australia supports ARR as part of its role to provide authoritative, independent information and advice to the Australian Government and other stakeholders to support risk mitigation and community resilience. ARR is pivotal to the safety and sustainability of Australian infrastructure, communities and the environment. It is an important component in the provision of reliable and robust estimates of flood risk. Consistent use of ARR ensures that development does not occur in high risk areas and that infrastructure is appropriately designed.

Mineral exploration in Australia faces the challenge of declining discovery rates despite continued exploration investment. The UNCOVER roadmap, developed by stakeholders from industry, government and academia, has highlighted the need for discovering mineral resources in areas of cover. In these areas, potentially prospective basement is covered by regolith, including transported sediment, challenging many traditional exploration methods designed to probe outcrop or shallow subcrop. Groundwater-mineral interaction in the subsurface has the potential to give the water geochemical and isotopic characteristics that may persist over time and space. Geoscience Australia’s hydrogeochemistry for mineral exploration project, part of the Exploring for the Future Programme, aims to use groundwater chemistry to better understand the bedrock-regolith system and develop new methods for recognising mineral system footprints within and below cover. During the 2017 dry season (May to September), ~150 groundwater samples (including QC samples) were collected from pastoral and water supply bores in the regions of Tennant Creek and McArthur River, Northern Territory. The Tennant Creek region has a demonstrated iron oxide-hosted copper-gold-iron(-bismuth) mineral potential in the Paleoproterozoic and Mesoproterozoic basement and vast areas of regolith cover. Among the critical elements of this mineral system, the presence/absence of redox contrasts, iron enrichment, presence of sulfide minerals, and carbonaceous intervals can potentially be diagnosed by the elemental and isotopic composition of groundwater. The McArthur River region, in contrast, has demonstrated sediment-hosted stratiform lead-zinc-silver mineral potential in the Paleoproterozoic to Neoproterozoic basement and also vast areas of regolith cover. Here, critical mineral system elements that have the potential to be identified using groundwater geochemistry include the presence of felsic rocks (lead source), carbonate rocks (zinc source), basinal brines, dolomitic black shales (traps), and evaporite-rich sequences. Preliminary results will be presented and interpreted in the context of these mineral systems.

Following a Government decision in 1984, Geoscience Australia actively engages in nuclear monitoring activities on behalf of the Australian Government through the Department of Foreign Affairs and Trade's Australian Safeguards and Non-proliferation Office. Geoscience Australia helps Australia fulfil its obligations under the CTBT by monitoring for nuclear explosions worldwide and by contributing to the development of the CTBT verification regime. Geoscience Australia is currently responsible for the operation and maintenance of 10 of Australia's seismo-acoustic IMS facilities (six seismic stations, three infrasound stations and one hydroacoustic station). Additionally, Geoscience Australia is in the process of building the final infrasound station to complete Australia's seismo-acoustic IMS network. Construction of this station is expected to be completed within the next two years. Geoscience Australia actively participates in international fora dedicated to technological advances supporting nuclear non-proliferation and verification, and to the use of IMS data for civil and scientific applications. The latter include tsunami-warning and the monitoring of earthquakes and volcanic eruptions.

Prior to the advent of satellite imagery in the 1970s, extensive use was made of aerial photography to systematically image and capture land information. As part of national mapping and survey campaigns run by its predecessors, Geoscience Australia (GA) is custodian of some 1.2 million aerial photos dating back to 1928. Through these campaigns every part of Australia and its external territories was imaged at some point and often repeatedly over the last 90 years, forming a unique and invaluable historical collection. Most importantly, they enable us to extend the record of surface land changes back an additional 50 years or more. GA is progressively moving this collection from analogue to a modern digital data management framework. Discoverability and access to data are essential to realising the full potential of the collection, and associated flight line diagrams are critical in connecting physical and digitised material in the collection to an accurate location consistent with modern datums. The focus of digitisation has been on scanning film and storing individual frames as photo images. Both flight line diagrams are also being digitised and georeferenced, and information on the film is transcribed into a structured database, which will drive a future catalogue for open online access. Only a subset of the aerial photos have been digitised, based on preservation concerns and specific use-cases. GA also is prototyping a new processing workflow to value-add to the digitised collection by creating products that are readily consumable into geographic information systems and as web services. This work may lead to further investment in digitisation by demonstrating broader utility and continuing collaboration with other stakeholders such as the National Archives of Australia. This will be needed to complete the modernisation vision, As with other historic data remediation, surprising finds have been unearthed, gaps in supporting information identified, and an untapped but largely recognised desire for the data. GA is investigating possible applications of citizen science to aid in the modernisation of this collection. This presentation will look at the process undertaken, the type of data available, and will outline some examples of the data, and future use. <b>ePoster is no longer available for access</b>
