The Surface Hydrology Points (Regional) dataset provides a set of related features classes to be used as the basis of the production of consistent hydrological information. This dataset contains a geometric representation of major hydrographic point elements - both natural and artificial. This dataset is the best available data supplied by Jurisdictions and aggregated by Geoscience Australia it is intended for defining hydrological features.

The RadWaste Reporting Tool allows Dept of Industry and GHD staff to analyse and compare Multi Criteria Analysis (MCA) ratings of a site within a nominated location and ascertain the reason for the ranking and score. This tool also outputs a snapshot of the nominated site, giving a context map and scores against requirement criteria.

Extensive historical (anecdotal) information covering the past 3 decades indicated that the remote and pristine Nadgee lake estuary in southern NSW had a benthic dominated ecology. All descriptions indicated that it had oligotrophic waters with dense cover of benthic macropyhtes and associated avifauna. When we arrived at Nadgee in late 2008 for the first scientific aquatic survey (ever) it looked nothing like this. The lake was dominated by an intense microalgal bloom and no macrophytes were present. Why? Entrance opening and closure are the major disturbances in an intermittent estuary like Nadgee, but there are no records of past entrance behaviour for such a remote site. This paper describes the use of Geoscience Australia's recent compilation and rectification of Landsat images (the Australian Geoscience Data Cube), along with the application of a consistent water detection tool for all pixels in that compilation, to determine opening and closing regimes. The output of the analyses provides an indication of whether a pixel was wet or dry (or not able to be determined) for all images over the entire 27 year's worth of data. Water level records measured by OEH since 2009 were used to ground-truth the remote sensed data. We can now determine when, over the past 27 years, the Lake opened and how long the water level remained low. This information, along with an understanding of the ecology of the primary macrophytes has been used to provide some possible models that explain when and why the fundamental shift from benthic to pelagic may have occurred.

Geoscience Australia in collaboration with the Geological Survey of Western Australia (Royalties for Regions Exploration Incentive Scheme), the Department of State Development South Australia and AuScope funded the Eucla-Gawler 2D deep seismic survey. The seismic survey acquisition and processing were managed and processed by Geoscience Australia. Geokinetics Australasia Ltd were contracted to collect the Eucla-Gawler 2D deep seismic reflection survey from November 2013 to February 2014. Deep seismic reflection data and gravity readings were acquired along the 834 km seismic line. Magnetotelluric (MT) data (Duan et al, 2015) were also acquired along the seismic line after the completion of the seismic survey. The main objectives of the project are to acquire deep crustal seismic data to (Geoscience Australia, 2013): (1) Image the crustal architecture of the geology underlying the Eucla Basin and its relationship to the Gawler Craton to the east and the Yilgarn Craton to the west; (2) Establish the subsurface extent of the Eucla Basin and look for large structural zones that may have provided fluid pathways for mineralisation.

RadWaste Decision Support System (DSS) allows Dept. Industry and GHD stakeholders to perform multi criteria analysis (MCA) against the 30 mandatory requirements for each land submission for consideration for consideration for the national radioactive waste storage site. The shorlisted sites will need to be suitable for the long-term storage of low-level and medium-level radioactive waste. The storage site is expected to have a 500yr lifecycle; 100 years active, 400 yrs managed closure.

Exploration geologists are increasingly being inundated by a large volume and variety of digital spatial data. Unsupervised clustering algorithms, such as Self-Organizing Maps (SOM), provide an opportunity to gain insight into complex geological phenomena not evident from a single dataset. Unsupervised clustering algorithms are able to efficiently integrate and recognize patterns within 'Big Data' into manageable and interpretable outputs. This study demonstrates data fusion for mineral exploration and highlights the potential for data-driven clustering analysis to assist geoscientists in gaining robust understanding of the geological controls on mineralization in regolith dominated terrains. We interpret the nature of Uranium mineralization across the Australian continent by integrating remotely sensed, continental-scale geophysical and mineralogical data using SOM. We combine the outputs of our cluster analysis with Uranium mineral occurrence data (n = 1138) to construct prospectivity maps of regional Uranium mineralization for the Australian continent. Furthermore, we divide prospective areas into several unique groups. These groups represent subtle but significant differences in regolith and bedrock geophysical and mineralogical characteristics of Uranium mineralization targets. A total 11.94% of the samples input into the SOM analysis are likely to be prospective for Uranium mineralization. The resulting Uranium prospectivity map identifies the location of Uranium mines (operating and historic) with an accuracy 88.89% (n = 119). By interrogating the unique geophysical and mineralogical characteristics of Uranium prospectivity groups we can distinguish regions of: older landscapes with subdued topography dominated by arid climatic conditions and mechanical weathering processes; and relatively young landscapes over thin crust exhibiting moist climatic conditions and deeply weathered regolith profiles. These broad groups can be further subdivided into areas likely to represent magmatic-hydrothermal, unconformity and calcrete-hosted paleochannel Uranium deposits. The clustering analysis methodology presented here can be applied to the analysis of other bedrock and regolith associated mineral commodities and at local- and/or prospect-scales. Our techniques provide additional tools for the exploration geologist to develop a robust understanding of likely geological context of target mineralization. In turn, this will help to define the geological controls on mineralization and will contribute significantly to developing appropriate exploration strategies.

The National Flood Risk Informaiton Project (NFRIp) has produced a flyer for the Floodplain Management Association Conference on 19-22 May 2015 where the Australian Flood Risk Information Portal (AFRIP) will be promoted at a Geoscience Australia booth. NFRIP funded the revision of the guidelines as part of a $12m funding initiative by the Australia Government. The flyer promotes the three core activities of NFRIP; the Australian Flood Risk Information Portal, revision of Australian Rainfall and Runoff guidelines and Water Observations from Space (WOfS).

Compilation of new and existing data can be used to show systematic variations in initial ore-related Pb isotope ratios and derived parameters for the Lachlan and Delamerian orogens of southeast Australia. In addition to mapping tectonic boundaries and providing genetic context to mineralising processes, these variations map mineralised provinces at the orogenic scale and can provide vectors to ore at the district scale. In New South Wales and Victoria, mapping using a parameter termed the 'Lachlan Lead Index' (LLI), which measures relative mixing between crustal- and mantle-derived Pb using the curves of Carr et al. (1995, Economic Geology 90:14671505), clearly demarcates the boundary between the Eastern and Central Lachlan provinces, and seems to identify boundaries between zones within the Western Lachlan Province of Victoria. The LLI also maps the extent of the isotopically juvenile Macquarie 'Arc' in New South Wales. However, rocks in the Rockley-Gulgong Belt, initially mapped as part of the Macquarie Arc, have a more evolved isotopic character, suggesting that these rocks are not part of the Macquarie Arc. This interpretation supports recent mapping that casts doubt on the attribution of this belt to the Macquarie Arc (Quinn, et al., 2014, Journal of the Geological Society of London 171:723736). The LLI has also identified small exposures of Ordovician volcanic rocks, well removed from the main Macquarie Arc, as possible correlates to this arc, with potential to host porphyry and epithermal deposits. Metallogenically, porphyry Cu-Au deposits in the Macquarie Arc are characterised by juvenile Pb. In contrast, Sn and Mo deposits in the Central Lachlan Province (i.e., the Wagga tin belt) are characterised by highly evolved Pb even though these deposits formed over 30 million years. Moreover, the Pb isotope data suggest that the original interpretation that copper deposits in the Girilambone district are volcanic-associated massive sulfide deposits was correct and that these deposits formed in a back-arc to the Macquarie Arc at ~480 Ma. In the Mount Read Volcanics of western Tasmania, all deposits appear to cluster along the same growth curve. However, when divided according to age (i.e., Cambrian (~500 Ma) versus Devonian (~360 Ma)), spatial patterns are visible in 206Pb/204Pb data. For Cambrian deposits 206Pb/204Pb decreases overall to the southeast, although low values are also present in the far south (i.e., Elliott Bay) and northeast. The most highly mineralised central part of the belt seems to be broadly associated with the zone of highest 206Pb/204Pb. Variations in 206Pb/204Pb for Devonian deposits broadly mimic the patterns seen for the Cambrian deposits. More importantly, a district-scale pattern in 206Pb/204Pb is present in the Zeehan district. Isotopically, the Sn-dominated core of the Zeehan district (e.g. Queen Hill and Severn deposits) is characterised by high 206Pb/204Pb, which decreases outward into the Zn-Pb-Ag-dominated peripheries. Lead isotope distribution patterns can potentially be used as an ore vector in this and other intrusion-centered mineral systems.
