Strategic communication practices in Australian Government science organisations

08 February 2017

Are Australian Government science organisations strategic in their communication efforts, or not? And why does this matter? A recent study of 20 such organisations, including Geoscience Australia, sheds light on these questions; finding that many of the organisations have room to improve when it comes to using communication to support business outcomes.

Introduction to Observational Seismology Lecture Series

2016

Lutetium-Hafnium and Oxygen-isotope analyses on zircons are techniques that Geoscience Australia has recently started using to trace the source of rocks back through time. This talk will outline the basics of these tools, demonstrate an application in the southern Thomson Orogen in New South Wales and outline plans for upcoming work programs including the Exploring for the Future initiative.

Potential impacts of marine seismic surveys on fish and invertebrates

07 December 2016

An important part of managing Australia's marine resources is mapping the geology beneath the sea floor using seismic surveys.  As part of this work, we must understand and mitigate associated environmental impacts. This presentation will outline Geoscience Australia's environmental mitigation strategies, as well as results from a recent study examining the effects of a Bass Strait seismic survey on fish and scallops. 

Science 101: Introduction to Mineral and Energy Resources

09 December 2016

'Introduction to Mineral and Energy Resources' is the second in the Science 101 seminar series providing an introduction to a range of scientific topics related to Geoscience Australia's work. No prior technical knowledge is required.

The Anthropocene Ocean

14 December 2016

The human imprint on Earth surface processes and features is now at a point that a new geological epoch, the Anthropocene, has been proposed. What human impacts on the Earth's crust, ocean, atmosphere, and cryosphere give rise to the idea that we have brought about a new geological regime? From a geological perspective, how will the Anthropocene be recorded in the geological record? What would geologists in the far future see at the sedimentary horizon coincident with humans' recent time on the planet?

Hafnium-isotopes: a new tool for Geoscience Australia

30 November 2016

Lutetium-Hafnium and Oxygen-isotope analyses on zircons are techniques that Geoscience Australia has recently started using to trace the source of rocks back through time. This talk will outline the basics of these tools, demonstrate an application in the southern Thomson Orogen in New South Wales and outline plans for upcoming work programs including the Exploring for the Future initiative.

National water infrastructure development and water resources

23 November 2016

The Australian Government is currently implementing a level of investment in water resources development and management that is almost unprecedented in Australian history.  The importance of underpinning this investment with good science and technical (including economic) analysis will be discussed.

Geoscience Australia's Hidden Gem: The National Mineral and Fossil Collection

16 November 2016

The National Mineral and Fossil Collection contains an impressive selection of around 50 000 specimens, with approximately 800 on permanent display in Geoscience Australia's foyer in Canberra. This talk will give an overview of this amazing collection, its history and its future.

Initial results from 2D seismic survey in the frontier northern Houtman Sub-basin

09 November 2016

New 2D seismic data, acquired by Geoscience Australia in the northern part of the offshore Perth Basin show the presence of a large depocentre, which potentially contain multiple source rock intervals, reservoirs and seals. Geoscience Australia is undertaking a study to assess prospectivity of this depocentre for oil and gas by integrating results from seismic mapping, geophysical modelling and petroleum systems analysis.

Geoscience Australia Laboratories: this is what quality looks like and why it is important

02 November 2016

Geoscience Australia laboratories consist of a range of Palaeontology, Sedimentology, Isotope, Geochemistry, Mineralogy and Geochronology facilities. This 30 minute presentation will be followed by a tour of the laboratories. Numbers are limited to 20, with bookings required for the tour. Read more to register.
