ITC’s role in Geoscience for sustainable development

13 February 2019

The Netherland's University of Twente’s Faculty of Geo-Information Science and Earth Observation (ITC) has acted as a knowledge hub since its inception in 1950. ITC has developed a broad global network of +25 000 alumni and strategic partnerships, and it wants to continue to actively pursue and elaborate international partnerships within our geo spatial knowledge domains.

SAGE - The journey to Bronze Accreditation

06 February 2019

15 institutions, including ANSTO and CSIRO were awarded Bronze Accreditation at the Inaugural Athena SWAN Awards night last December - and we were there. Find out what being Bronze Accredited means to the organisation and what GA is doing to get there.

Late Permian volcanism and the timing of end Permian Mass Extinction in Australia

12 December 2018

Uranium lead-dating of ashfall tuffs allows for high-precision correlation of units and events. For example, late-Permian volcanism in Eastern Australia is contrasted with the Siberian Traps and their relationship with the end-Permian Mass Extinction. Also, dating evidence suggests a potential 370 ka disparity between the initiation of Terrestrial and Marine Permian Mass Extinction events.

An updated National Seismic Hazard Assessment for Australia: Are we preparing for the right earthquakes?

05 December 2018

Geoscience Australia has released the new National Seismic Hazard Assessment — NSHA18. This assessment defines the level of earthquake ground shaking that has a given likelihood of being exceeded in a given time period and incorporates best practice and evidence based science. The updated assessment provides a benchmark for building and infrastructure design to ensure structures can withstand future earthquake events in Australia. It also serves as a benchmark to set insurance and re-insurance premiums across the country.

DiSI Bi-annual Showcase

28 November 2018

The Digital Science and Information Branch (DiSI) at Geoscience Australia will showcase their achievements over the last six months. Come and see the latest innovations in our digital products and capabilities, within the sphere of Digital Science Platforms, Scientific Computing, Infrastructure Integration and Data Informatics; along with achievements in Client Services, Collection Management and Education programs.

CEO seminar - The value of the geosciences to society

23 November 2018

The geosciences provide tangible benefits to Australians, often in ways they are completely unaware of.  This presentation will highlight key examples of the value the geosciences provide to society across a number of disciplines including Earth observation, geodesy, geography, marine geoscience, geology, geophysics, hydrogeology, and geohazards.

Revealing the Australian Continent at its Barest

21 November 2018

A barest earth (i.e. least vegetated) Landsat mosaic over the Australian continent has been generated using a novel high-dimensional statistical technique. This talk will discuss the methodology used to generate the barest imagery and the utility of the product for enhanced geological mapping.

Can deep seismic reflection profiling image the fluid migration pathways in mineral systems?

14 November 2018

GA uses seismic imaging in studies of the prospectivity of mineral provinces. But research in the Yilgarn Block of WA mapped fluid behaviour in areas of high prospectivity, and showed that the technique can also directly image the pathways that mineralising fluids take from the deep crust to ore deposits.

Lean Transformation - Building Blocks For Success

31 October 2018

Presented to the Lean Thinking and Practice Australasia conference in May 2018.  This presentation covers a true story of implementing Lean thinking in Geoscience Australia Information Technology (IT) systems captured within the theme of transformation.

How understanding past glacial landscapes can inform present day Windfarm site investigations: A case study of large-scale glacitectonism during active ice sheet retreat across Dogger Bank, southern central North Sea

10 October 2018

The integration of high-resolution geophysical and geotechnical datasets acquired during a site survey for the Dogger Bank windfarm has enabled a detailed litho-and seismo-stratigraphy to be established. Understanding these landscapes, coupled with the geophysical and geotechnical data, enables a predictive "geo-model" to be established. This model involves repeated phases of folding and thrusting in response to major ice sheet advance and retreat.
