The rise of algae in Cryogenian oceans and the emergence of animals

18 July 2018

The transition from bacterial to complex eukaryotic oceans was one of the most profound revolutions in our planet's history. Dr Jochen Brocks will present results from a recent Nature paper demonstrating that algae conquered the oceans between two Snowball Earth glaciations 659 Myrs ago, and this event was responsible for the emergence of our earliest animal ancestors.

Airborne electromagnetics at an unprecedented scale

11 July 2018

The talk outlines the airborne electromagnetic technique, the underlying challenges in acquiring quality calibrated data and reliable modelling and inversion results. We will demonstrate how Geoscience Australia is using the technique to map cover thickness at unprecedented scales.

Geology Makes a Difference - Geohazards Analyses Offshore Western North America Using Multibeam Bathymetry and Geophysical Data

09 July 2018

Keynote address by internationally recognised marine geologist and pioneer of habitat mapping and classification, Dr Gary Greene.

Government Open Data - how the convergence of open government, mass collaboration platforms, and new startups are generating new innovative uses of data and improving all of our lives.

04 July 2018

Open Data is a rapidly growing field where governments are able to improve their own transparency and performance, connect better with their citizens, and fuel innovation. However, there are many challenges and risks associated with open data. Government agencies need to be smart in how they understand and manage these risks. 

Positioning Australia for the Future

27 June 2018

Satellite positioning is a fundamental national capability for industry and society. This talk will overview the Australian Government's recent announcement to provide $225 million in funding for improved satellite positioning to ensure that Australia leads the world in this important space capability.

Emerging trends in geophysical inversion: From probabilistic inference to Data Science

20 June 2018

This talk presents an overview of current and emerging trends in the field of geo-data analytics and the solution of inversion problems. A particular focus is on rigorous quantification of both parameter and conceptual uncertainty. Simple examples will illustrate the main ideas with applications including Earth imaging.

Helium in Australia's Liquefied Natural Gas Economy

06 June 2018

Helium is a critical commodity. Helium abundance and its origin in Australian natural gases will be presented. In the short to medium term helium extraction will be linked with LNG processing. Operating, committed and proposed LNG projects across Australia have been rated for their helium extraction potential.

Digital Earth Australia - From Satellites to Insights

30 May 2018

Digital Earth Australia (DEA) will provide government and businesses unprecedented access to satellite imagery tailored for Australia. This talk will showcase how DEA is being used to manage environmental changes across our vast continent as well as outlining how DEA will be used to develop new applications for sectors across the entire Australian economy.

International Collaboration in Support of Indonesian Earthquake Hazard

23 May 2018

In order to improve the knowledge of Indonesian earthquakes following the 2004 Sumatra Earthquake and Indian Ocean Tsunami, the Government of Australia supported a technical capacity-building program that brought Australian and Indonesian earthquake scientists together to focus not only on improved science, but also on cooperation among government and academia to effectively utilize the science to help Indonesian society protect itself from future earthquakes.

Planting SEEDS to Maximise Data Potential: The Geoscience Australia Data Strategy

02 May 2018

In order to maintain its reputation as a pre-eminent geoscientific and spatial data agency, Geoscience Australia must strive to maximise data's potential. To successfully maximise data potential, a number of objectives will need to be achieved. These objectives, or SEEDS, form the basis of the Geoscience Australia Data Strategy.
