Between 2006 and 2011, Geoscience Australia has acquired deep crustal seismic reflection and magnetotelluric surveys as a major component of the Australian Government's Onshore Energy Security Program (OESP). All surveys have been conducted in collaboration with the relevant state or NT geological survey. The Seismic Acquisition and Processing Project provides precompetitive data for developing new geological frameworks for assessment of onshore hydrocarbon, geothermal and uranium resources. The Onshore Petroleum Project provides interpretation of the seismic data in frontier basins with petroleum potential and an assessment of the petroleum prospectivity of these basins. Seismic data can reveal basin and crustal architecture for potential hydrocarbons, image potential hot rocks (granites), and identify potential uranium deposit settings, such as craton margins and unconformities.

Specification of a Global Nested Grid System for Use by Australia and New Zealand Matthew Purss1, Stuart Minchin1, Adam Lewis1, Simon Oliver1, Lesley Wyborn1, Robert Gibb2, Alex Fraser3, Ben Evans4 1 Geoscience Australia, Canberra, Australia, Matthew.Purss@ga.gov.au 2 Landcare Research, Palmerston North, New Zealand, gibbr@landcareresearch.co.nz 3 Victorian Partnership for Advanced Computing, Carlton, Vic, Australia, adfries@vpac.org 4 Australian National University - National Computational Infrastructure, Leonard Huxley Building, Canberra, ACT, Australia, Ben.Evans@anu.edu.au BACKGROUND Geoscientific data has already exceeded the peta-scale barrier. Converting this massive amount of data into timely information and decision support products is dependent on our capacity to rapidly analyse this data in a transparent and repeatable fashion. This can only be achieved through the conversion of traditional data archives into standardised data architectures that support parallel processing in high performance compute environments. In the near future, the challenge of high velocity, high volume (> a terabyte per day) will further increase the requirement for standard data structures that support the massively parallel processing required to convert high velocity data into near-real-time decision support information. One of the key elements of standardised data architecture is a common grid. A nested grid that supports global data models is required to ensure that the grid is capable of handling multiple input data streams rather than being sensor/data stream dependent. REVIEW OF THE ANZLIC NATIONAL NESTED GRID SPECIFICATION The Australian and New Zealand Land Information Council (ANZLIC) National Nested Grid (NNG) specification provides a framework for the interchange of spatial data between various grid resolutions. The Primary aim of the NNG is to define a practical guide for a data grid framework that enables and encourages sharing, reuse and integration of grid cell data, both within and across jurisdictions [1]. Unfortunately, deficiencies in the NNG specification limit its application for multi-domain and regional to global scaled 'big data' problems. In August 2013, Geoscience Australia hosted a workshop to review the NNG specification and identify ways to incorporate a Global Nested Grid (GNG) system into the specification that will improve its application and acceptance for use in solving the geoscientific problems of the future. This paper reports on the outcomes of this workshop. THE RHEALPIX GLOBAL NESTED GRID SYSTEM The revised Hierarchical Equal Area iso-Latitudinal Pixelation (rHEALPix) GNG system [3,4] has been recommended for application to Australia and New Zealand. It is an extension of the astronomically focused discrete global grid system developed by NASA (HEALPix - based on spherical symmetry) to study cosmic background microwave radiation. Figure 1 shows a graphical representation of the rHEALPix GNG system. Brisbane | Australia 20-25 Oct | 2013 7th eResearch Australasia Conference By extending HEALPix so that it can be applied to ellipsoids of revolution, such as WGS84, Gibb et. al. [4] have broadened the use of this GNG system to include terrestrial applications. Key features of rHEALPix include: (a) It is hierarchical, congruent, aligned for odd values of an integer parameter Nside (which defines the nesting of each cell at different resolutions), and has a constant aperture; (b) At every resolution its grid cells have equal areas; (c) At each resolution its grid cells align to parallels of latitude, which makes computing spherical harmonics fast; (d) Its planar projection has a low average angular and linear distortion; and, (e) It can be used for ellipsoids of revolution, such as WGS84. eResearch Australasia 2013 - Brisbane

Geoscience Australia conducts applied research within the Australian Antarctic Territory and adjacent marine jurisdictions. This research supports Geoscience Australia's strategic objectives and the Australian Antarctic Science Strategic Plan, as well as providing quality advice to Government. Our research underpins development of appropriate environmental management strategies for a range of marine and terrestrial environments. Our work supports the Australian Government's national interests in the Antarctic and commitment to the Antarctic Treaty System.

Australia's government geoscience agencies work together as Australia Minerals to connect people, information and innovation to opportunities that give investors the confidence to invest in mineral exploration in Australia. This USB has been produced as a giveaway at international conferences and events attended by Australia Minerals (AM). This USB contains electronic material from each of the States and the NT grouped under the themes: Publications, Guides, Infrastructure, Maps, Mineral Resources Information, and Projects and Exploration. This version was produced for the Australasian Exploration Geoscience Conference held in Sydney in February 2018.

This CD contains three movies over computer generated surfaces taking you on a path at an upper atmosphere altitude following the Australian coastline. The surface images were generated from actual geophysical measurements, but the vertical scale has been enhanced and colours chosen for visual impact.

Content of flyer as follows: Geoscience Australia Coastal, Marine and Antarctic Geoscience Geoscience Australia provides geoscientific information and knowledge for the economic, social and environmental benefit of all Australians. The marine group in the Environmental Geoscience Division provides geoscientific information to support decision making across a range of natural resource and environmental issues in the coastal zone, the offshore marine estate and the Australian Antarctic Territory. The group also provides pre-competitive advice on offshore resources including the preparation of seabed environmental summaries for future acreage release areas and seabed mapping surveys in areas of planned offshore infrastructure development. Outputs include technical advice to Government on marine, coastal and Antarctic matters, as well as spatial data, maps, models and predictions of: marine geomorphology and geology seabed sediments and geochemistry seabed habitats and biodiversity marine ecosystem processes Current work is contributing to programs including: The search for MH370: Bathymetric Survey Casey Station Seabed Mapping Survey, Antarctic National Environmental Science Programme, Marine Biodiversity Hub Darwin Harbour Seabed Mapping National CO2 Infrastructure Plan Further information about the group's activities can be found on our webpage http://www.ga.gov.au/about/what-we-do/projects/marine Publications can be found at http://www.ga.gov.au/data-pubs
