In May 2016, Geoscience Australia entered into a Sub-Proposal of the Australia Mongolia Extractives Program (AMEP) [1]. The Sub-proposal was titled 'Review of the Geoscience data and data management government for the future NGS Database and Delivery Section' [2]. This work was originally proposed in the Mongolia Scoping Study written by Bridget Ayling and Aki Nakamura [9]. The Scoping Study identified the creation of a National Geological Survey (NGS) and a National Geoscientific Database as key recommendations. This report builds on [9]¿s Priority 2 (the creation of a National Geoscientific Database) by providing an assessment of existing geoscientific data governance and process. It identifies areas where international standards and best¿practice could be applied to increase efficiency and effectiveness in the use of geoscientific data. It also proposes a roadmap to address identified gaps in data governance and technology. The findings of this report are as follows: * There are several Mongolian Government organisations who collect and hold geoscientific data, mainly within the Ministry of Mining but also outside it (Environmental Information Centre within the Ministry of Environment and Greening); * There are well established and governed processes for the collection of some scientific reports, and the delivery of some forms of maps, mostly in hard copy; * There are gaps in the government policy framework regarding spatial data management and delivery and also departmental aggregated data generally; * There is uncertainty around the governance of the future NGS and whether it will incorporate or sit beside existing geoscientific agencies. On the basis of these findings, the report includes the following recommendations which are articulated in full detail in Section 10: Recommendation 1: Data Governance Policy The Mongolian Government should formally identify custodians of existing geoscientific data holdings and define rights and obligations of custodianship. Recommendation 2: Data Exchange Policy The Mongolian Government should develop a formal data exchange policy for geoscientific data. Recommendation 3: Catalogue Development The Mongolian Government should develop and publish a data catalogue listing the data holdings of all relevant agencies, including information on the data custodian and access policy. This catalogue should adopt key international standards for metadata and online catalogue delivery. The catalogue may initially be for internal government use only but should eventually be made public, even if all of the data within it is not directly accessible. The metadata for all datasets should be listed in the catalogue, even when the data is not made available. Recommendation 4: Digital delivery for data products The Mongolian Government should develop IT infrastructure to support data exchange and distribution to support making the data listed in the data catalogues available digitally. Not all of the catalogue¿s data will either be available digitally or freely. Recommendation 5: Adopt a roadmap to prepare for a future National Geological Survey The Mongolian Government should adopt a roadmap to implement Recommendations 1 - 4 and prepare for the establishment of an NGS with NGS structural decisions based on the progress of implementing Recommendations 1 - 4. Recommendation 6: Continued Cooperation with Geoscience Australia The Mongolian Government and Geoscience Australia should continue to share information and approaches on the management and delivery of geoscientific information. This is likely to benefit both institutions.

<div>The pyrolysis-reflectance tie database table contains publicly available results from Geoscience Australia's organic geochemistry (ORGCHEM) schema and supporting oracle databases, which combine key properties related to thermal maturity. These data are typically used as input parameters in basin analysis and petroleum systems modelling to assist with the discovery and evaluation of sediment-hosted energy resources. The programmed pyrolysis analyses and the maceral reflectance analyses undertaken using reflected light microscopy are conducted on rock samples, either as cores, cuttings or rock chips, taken from boreholes and field sites in Australian sedimentary basins. The full datasets are available in the pyrolysis, vitrinite reflectance, maceral reflectance and organoclast maturity web services. These analyses are performed by various laboratories in service and exploration companies, Australian government institutions and universities using a range of instruments.</div><div><br></div><div>These data are collated from destructive analysis reports (DARs), well completion reports (WCRs), and literature.

<div>The Petroleum Systems Summary database stores the compilation of the current understanding of petroleum systems information by basin across Australia. The Petroleum Systems Summary database and delivery tool provide high-level information of the current understanding of key petroleum systems for areas of interest. For example, geological studies in the Exploring for the Future (EFTF) program have included the Canning, McArthur and South Nicholson basins (Carr et al., 2016; Hashimoto et al., 2018). The database and tool aim to assist geological studies by summarising and interpreting key datasets related to conventional and unconventional hydrocarbon exploration. Each petroleum systems summary includes a synopsis of the basin and key figures detailing the basin outline, major structural components, data availability, petroleum systems events chart and stratigraphy, and a précis of the key elements of source, reservoir and seal. Standardisation of petroleum systems nomenclature establishes a framework for each basin after Bradshaw (1993) and Bradshaw et al. (1994), with the source-reservoir naming conventions adopted from Magoon and Dow (1994).&nbsp;</div><div><br></div><div>The resource is accessible via the Geoscience Australia Portal&nbsp;(https://portal.ga.gov.au/) via the Petroleum Systems Summary Tool (Edwards et al., 2020).</div>

The Geoscience Australia Data Strategy 2018-2021 is the enterprise strategy that outlines the initiatives that should be followed in order to maximise data potential.

<div>This guide and template details data requirements for submission of mineral deposit geochemical data to the Critical Minerals in Ores (CMiO) database, hosted by Geoscience Australia, in partnership with the United States Geological Survey and the Geological Survey of Canada. The CMiO database is designed to capture multielement geochemical data from a wide variety of critical mineral-bearing deposits around the world. Samples included within this database must be well-characterized and come from localities that have been sufficiently studied to have a reasonable constraint on their deposit type and environment of formation. As such, only samples analysed by modern geochemical methods, and with certain minimum metadata attribution, can be accepted. Data that is submitted to the CMiO database will also be published via the Geoscience Australia Portal (portal.ga.gov.au) and Critical Minerals Mapping Initiative Portal (https://portal.ga.gov.au/persona/cmmi).&nbsp;</div><div><br></div>

Interferometric Synthetic Aperture Radar (InSAR) is a proven geodetic imaging technique that makes use of remotely sensed radar imagery to map spatial patterns of ground surface movement and their temporal evolution. One application of the InSAR technique is to monitor human interactions with the landscape, such as the extraction of resources from the crust. The increasing demand for gas in Australia has led to increased extraction of unconventional coal seam gas (CSG) reserves, particularly in the Surat Basin in south-east Queensland. Proved and Probable reserves of CSG now exceed 32,000 Petajoules, making the Surat Basin the largest onshore gas reserve in Australia. The geological target of CSG extraction in the Surat Basin is the Walloon subgroup of the Jurassic period, which is typically between 300 to 600 metres depth. Production of CSG from the Walloon subgroup began in 2006 and reserves are currently being extracted by several operators, with combined extraction exceeding 160 Petajoules in 2013-2014. Predictions of the magnitude of subsidence in the Surat Basin based on analytical poroelastic models and quoted CSG production rates indicate that total subsidence on the order of a decimetre may occur. In this contribution we will present new InSAR analysis of the Surat Basin using multi-sensor SAR imagery spanning the 2006-2015 time period. Should patterns of subsidence be detected over the producing gas fields, we will use a geophysical inversion scheme to characterise the objective function between the spatial InSAR observations and predictions of a simple analytical model. Our methodology will make use of a Monte-Carlo sampling algorithm run on High Performance Computing architecture to efficiently sample the multi-dimensional parameter space. The homogenous poroelastic model we employ has dependence on the depth and thickness of the target geological unit as well as on the unit’s rock properties (porosity, Young’s Modulus, Poisson’s Ratio and Shear Modulus). Given that limited information about these properties is generally publically available for the Surat Basin, the geophysical inversion scheme will enable a sensitivity analysis to be conducted that will allow us to understand uncertainties and what parameters have the most significant impact on the system. This in turn will enable more accurate predictions of future subsidence using the poroelastic model. In 2014, Geoscience Australia installed a regional geodetic network over a sub-region of the north-eastern Surat Basin in the vicinity of the towns of Dalby, Miles and Chinchilla in Queensland. The network covers a region of approximately 20,000 km2 and consists of 40 co-located corner reflectors and survey marks. Ongoing SAR imaging of the corner reflectors and periodic campaign GNSS surveys on the survey marks will enable InSAR analysis to be combined with ground-based geodetic measurements and as a result, refine the geodetic reference datum in this region. Preliminary analysis of the persistent scatterer response of the corner reflector network will form a part of this contribution. A dense archive of Interferometric-Wide-Swath (IWS) and Extra-Wide-Swath (EWS) Sentinel-1A images is currently being acquired over the region since the permanently deployed corner reflectors are being used as targets for ongoing geometric and radiometric calibration of the Sentinel-1A SAR sensor. InSAR analysis of this Sentinel-1A data will also form a part of this contribution. Presented at the 2016 Living Planet Symposium (LPS16) Prague, Czech Republic
