Australia’s Open-Source Global Navigation Satellite System (GNSS) Analysis Centre Software

We are pleased to announce the forthcoming release of Ginan version 3, a suite of open-source Global Navigation Satellite System (GNSS) software tools developed and maintained by Geoscience Australia in collaboration with industry and academia under the Positioning Australia program.
Ginan serves as a precise point positioning (PPP) engine to produce real-time products that support high-precision positioning. Its versatility is demonstrated through its applicability to various geodetic and positioning activities, including computation of daily coordinate solutions, precise satellite orbit determination, computation of satellite clocks and biases, atmospheric modeling, and data quality assurance and quality control. These products effectively mitigate real-time errors associated with GNSS observations and are openly accessible as a centimeter-accurate correction service.
The primary objectives of Ginan are: (1) showcase Australia's unique modelling and analytic systems for multi-GNSS real-time processing, delivering precise positioning products to both the Australian and international Positioning, Navigation, and Timing (PNT) community; (2) offer expert advice on navigation system performance over Australia; and (3) provide state-of-the-art GNSS analysis center software to universities and research organizations, thus fostering Australia's leadership in geospatial technology development. In this presentation, we will provide an overview of Ginan version 3, highlighting its new features, the current development status, and the strategic roadmap for its continued use as an operational service. We will provide examples of Ginan’s usefulness as a platform for research and innovation including its use as the processing engine for research into atmospheric anomalies from the Tonga volcano eruption through monitoring travelling ionospheric disturbances that could be used as early warning and tsunamigenic predictors for disaster risk and reduction; and observations of the Turkyia earthquake.
The release of Ginan version 3 marks a significant advancement in GNSS data processing and positioning capabilities, contributing to the broader scientific community's understanding and utilization of geospatial technology.

Tsunami impact, education and community consultation in the communities of Onslow and Exmouth: a Geoscience Australia and Fire and Emergency Services Authority (WA) collaboration

The Natural Hazard Impacts Project (NHIP) at Geoscience Australia has developed modelling techniques that enable coastal inundation to be predicted during a tsunami. A Collaborative Research Agreement between Geoscience Australia and the Fire and Emergency Services Authority (FESA) was formed in 2005 to understand tsunami risk and inform emergency management in WA. Through this partnership a significant tsunami risk was identified in NW Western Australia, leading to the development of inundation models for several coastal communities in this region, including Onslow and Exmouth.  Recognising the importance of this research to Geoscience Australia, FESA and the communities of Onslow and Exmouth, this year's graduate project was designed to assist the NHIP and to further strengthen ties with FESA and community organisations. 
The project had several distinct outcomes which can be divided into data acquisition and community interaction. High quality elevation data was gathered by GPS surveying in order to ascertain the quality of the Digital Elevation Model (DEM) that is currently used in inundation models. Improved accuracy in the elevation data allows the capture of subtle changes in topography that may not be present in the existing DEM and so may improve model accuracy. Secondly, ground-truthing of predicted inundation areas supplements the survey data, provides critical assistance in the production of accurate inundation models and potentially aids in the production of emergency plans. 
Prior to fieldwork a community-specific tsunami awareness brochure was designed and produced for Onslow. This brochure was presented to Onslow local emergency managers and FESA personnel, and subsequently to Emergency Management Australia and the Bureau of Meteorology.  It has received widespread positive feedback, and consequently may provide a template for other community brochures in similarly vulnerable regions of Australia. Finally, graduates represented Geoscience Australia at several community meetings in Onslow where NHIP research was presented. These meetings provided insight into specific community concerns in the event of a tsunami and provided an opportunity for the attendees to ask questions about tsunamis and their impacts. Fortuitously this community interaction also led to the discovery of anecdotal evidence of past tsunami events in Onslow, including the tsunami triggered by the 1883 Krakatau eruption, a 1937 tsunami that may be attributed to an earthquake near Java, and the 1994 and 2004 tsunamis.

AUSGeoid98 v.1.0 data files: (sf48-04)

AUSGeoid98 data files contain a 2 minute grid of AUSGeoid98 data covering the Australian region, which you can use to interpolate geoid-ellipsoid separations for the positions required.You can use your own interpolation software, or you can use Geoscience Australia's Windows Interpolation software (Winter). The data files are text files in a standard format that cover the same area as standard topographic map areas. Files covering both 1:250,000 (approximately 100 x 150 km) and 1:1,000,000 (approximately 400 x 600 km) map areas are available. There is a 4 minute overlap on all sides of each area. Data format: AUSGeoid98 data files have a header record at the start of each file, to distinguish them from the superseded AUSGeoid93 data files. AUSGeoid98 data files show the geoid-ellipsoid separation to 3 decimal places, while the superseded AUSGeoid93 data files showed only 2 decimal places. AUSGeoid98 deflections of the vertical were computed from the geoid-ellipsoid separation surface, while the AUSGeoid93 deflections of the vertical were computed from OSU91A.

Regional chemostratigraphic framework of the Neoproterozoic and Middle Ordovician mega-sequences of the Officer Basin, Australia

The Neoproterozoic to Middle Ordovician sediments of the Officer Basin, Australia are difficult to correlate, in part because biostratigraphic studies of acritarchs and stromatolites are localised, isotopic studies are rare, and seismic models are technically challenged by the occurrence of basaltic and halite prone-sections. Hence, the chemostratigraphic framework presented here provides an independent stratigraphic model for the Neoproterozoic to Middle Ordovician sediments of the Officer Basin. A total of six chemostratigraphic mega-sequences have been geochemically defined and assigned to the stratigraphy; these have been further subdivided into twenty-eight chemostratigraphic sequences. The chemostratigraphic zonation has been established upon elemental changes attributed to provenance and climatic variation which can be used for correlation as they convey regional, rather than local, changes in sedimentation. The elemental data reveals that there is lateral variation within the established lithostratigraphy (e.g., within the members of the Observatory Hill and Hussar formations), which is suggestive of localised sediment source input to different areas of the basin.

The Poodyea Formation: a possible tertiary fluvial unit in the Toko Syncline, Georgina Basin, Queensland and Northern Territory

The Poodyea Formation, comprising boulder conglomerate, cross-stratified sandy conglomerate and pebbly sandstone, crops out as narrow linear and sinuous belts of small outliers within and to the south of the Toko Range, in the Georgina Basin, western Queensland and Northern Territory. The outliers are confined to present-day narrow valleys in the Carlo Sandstone, corresponding closely to either the Toko Syncline axis or cross-cutting structures, and form low linear ridges over plains of Mithaka Formation. The Poodyea Formation is considered to be of probable Tertiary age, and represents a river-channel deposit derived from reworking of parts of the Mesozoic, Palaeozoic, and Proterozoic sequences. In the past, outcrops of the formation have been included in Palaeozoic units. The formation is discussed and defined.
