Geoscience information and Web 3.0: what Geoscience Australia is doing at the forefront of scientific data delivery

08 March 2017

Publishing geoscience information is one way Geoscience Australia adds value to the nation. Web 3.0 technologies enhance information discoverability and description for people and enable the machine-to-machine Internet. This talk will describe what Web 3.0 is and how Geoscience Australia is leading government in its use of it. 

Delivering Geological Data Using Web Services and International Standards

01 March 2017

Web services have become the accepted way of delivering free and open spatial data over the internet from government data providers.  This presentation will show how web service data standards, such as GeoSciML, are used to ensure that data conform to agreed structures and can be used to support evidence-based analysis and research.

National Positioning Infrastructure - Testing a Satellite based Augmentation System (SBAS)

22 February 2017

This presentation will give a brief introduction to the National Positioning Infrastructure Capability (NPIC) and its components. Details will be provided of the Satellite Based Augmentation System (SBAS) testbed (NPIC component 1) that was funded in the 2016/17 MYEFO and commenced in February 2017.

Faults, gases and leakage: Locating and quantifying CO2 and methane leaks

15 February 2017

How do you find and measure leakage from geological storage sites or gas fields? This talk will provide an overview of our understanding of the gas migration behaviour in the near surface gained through large field experiments and observations at natural seepage sites. 

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.
