Southern McArthur Basin Gravity p201381 Complete Spherical Cap Bouguer First Vertical Derivative

Gravity data measure small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
This Southern McArthur Basin Gravity p201381 Complete Spherical Cap Bouguer First Vertical Derivative is the first vertical derivative of the complete spherical cap Bouguer anomaly grid for the Southern McArthur Basin Gravity Survey 2013 (P201381).

Seismic Risk Assessment of Critical infrastructure through Public-Private Partnerships in Australia

Communities and the wider economy rely upon a broad range of interdependent infrastructure systems. These systems may incorporate components having physical vulnerabilities to earthquake ground motion and may also have systemic vulnerabilities if components are damaged. The development of an understanding of these vulnerabilities and the opportunities to mitigate them typically entails a cross-sector approach and the incorporation of applied science inputs from the private sector and government. This paper describes the recent establishment of trusted public-private partnerships between government science and industry in Australia to develop actionable information. In particular, the arrangements for managing and sharing data and derived information is described in an environment now driven by cyber security concerns.

Australia sits within an intraplate environment with a seismic hazard ranging from low to the threshold of moderate on a global scale. Notwithstanding this, much of Australia’s critical infrastructure has been developed without an adequate consideration of this hazard that has led to issues where inherently vulnerable assets are operated in localities having higher hazard. These vulnerabilities are of concern to asset managers who recognise the benefit of collaboration with other industry sectors and science agencies to address them but need trusted arrangements to bring together the expertise. An example of a public-private partnership arrangement that has enabled this is the “Earthquake Impact and Risk Assessment for Perth and Supporting Infrastructure” project (EIRAPSI) co-funded by the Global Earthquake Model Foundation and Geoscience Australia. The outcomes of this project in the electricity transmission, potable water and road transport sectors in Western Australia are described along with the trusted sharing arrangements that made them possible.

Subsequently EIRAPSI has led to a broader sequel partnership, “Risk Assessment and Mitigation Study of Earthquakes in the Yilgarn” (RAMSEY) which is nearing completion. The project has navigated through new Australia Government legislation related to the security of critical infrastructure systems and intended to protect knowledge that could have potential use by malevolent actors. The challenge of balancing public good versus security sensitivities and the implications for future public-private partnerships in an ever-evolving environment of geopolitical and technological threats are discussed.

Evaluating zircon initial Hf isotopic composition using a combined SIMS-MC-LASS-ICP-MS approach: a case study from the Coompana Province in South Australia

The accessory mineral zircon is the most widely used geological timekeeper and tracer of crustal growth processes. Specifically, U-Pb isotopes in zircon offer a means to accurately determine the timing of magmatic events and their Hf isotopic composition provides a means to constrain magma source composition and potentially approximate source age. The high spatial resolution provided by in situ techniques such as secondary ion mass spectrometry (SIMS) and laser ablation inductively coupled mass spectrometry (LA-ICP-MS) have the advantage of being able to target different growth zones within individual zircon crystals, and unravel complex magmatic histories. However, utilising this power effectively requires calculation of accurate initial Hf compositions, which are founded on the assumption that the information obtained via the U-Pb and Lu-Hf systems are correctly integrated. A typical Hf isotope LA-ICP-MS analysis ablates a sample volume that is two orders of magnitude greater than a typical SIMS analysis. Thus, when age determination has been carried out by SIMS it is necessary to demonstrate that each subsequent Hf isotope analysis has sampled a similar isotopically homogeneous volume. Here, we use a combined SIMS and laser ablation split stream (LASS)-ICP-MS approach, whereby U-Pb isotopic measurement concurrently on the same sample volume as the Hf isotope measurement is compared to prior lower volume SIMS measurements. Using a suite of new drill core magmatic rock samples from the comparatively unexplored Coompana Province in South Australia, we demonstrate how such an approach can be used to filter Hf isotope datasets by identifying LA-ICP-MS analyses that sampled mixtures of different zircon growth domains. The robust initial 176Hf/177Hf compositions obtained from the filtered Coompana data set indicate that the province represents part of a juvenile Paleoproterozoic-Mesoproterozoic arc system formed through hyperextension of the margin of the Archean Gawler Craton, which can be correlated to the Musgrave Province and Madura Province in central and western Australia respectively. This hyperextension process is temporally similar to that on the now-adjacent Archean Yilgarn Craton margin.

Onshore active seismic and passive seismic database

The active seismic and passive seismic database contains metadata about Australian land seismic surveys acquired by Geoscience Australia and its collaborative partners. 
For active seismic this is onshore surveys with metadata including survey header data, line location and positional information, and the energy source type and parameters used to acquire the seismic line data. For passive seismic this metadata includes information about station name and location, start and end dates, operators and instruments. Each also contains a field that contains links to the published data.  

The active and passive seismic database is a subset of tables within the larger Geophysical Surveys and Datasets Database and development of these databases was completed as part of the second phase of the Exploring for the Future (EFTF) program (2020-2024). The resource is accessible via the Geoscience Australia Portal&nbsp;(https://portal.ga.gov.au/), under 'Geophysics'. Use 'active seismic' or 'passive seismic' as search terms.

Results of the National GNSS CORS Campaign, September 2014

An Australian-wide certification campaign of positions in accordance with Regulation 13 of the National Measurement Regulations 1999 and the National Measurement Act 1960 has been run from 00:00:00 (UTC time) Sunday 07 September 2014 to 00:00:00 (UTC time) Sunday 14 September 2014 (GPS week 1809). The primary objective of this campaign was to improve the consistency of legally traceable CORS positions across Australia, and confirm that CORS stations with a valid Regulation 13 Certificate conform to their stated uncertainties. As of 30 November 2014, twelve applications for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 have been received for verification of GDA94 position on their owned or managed station monuments. This report documents the processing and analysis of the national Regulation 13 campaign GPS data for the stations to satisfy the position verification requirements.

Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.
 These line dataset from the Edjudina, WA, 1984, 1988/89 survey were acquired in 1984 by the WA Government, and consisted of 52720 line-kilometres of data at 400m line spacing and 100m terrain clearance. To constrain long wavelengths in the data, an independent data set, the Australia-wide Airborne Geophysical Survey (AWAGS) airborne magnetic data, was used to control the base levels of the survey data. This survey data is essentially levelled to AWAGS.

Australian magnetic observatories

Magnetic observatories capable of providing long-period results in absolute measures have been operated in Australia and its territories on and off since 1840. As the first such observatory (that at Gottingen, built by Gauss) was erected only eight years earlier, a long tradition has been established in the observational aspects of the science. In 1979 six observatories are operating: one in Papua New Guinea (recently transferred to that countrys Geological Survey), three in Australia, one in the sub-Antarctic, and one in Antarctica. The number and disposition of continental observatories is inadequate. The factors which should be considered in planning any future network are outlined.
