Environmental Geoscience Division: Enabling sustainable development of our land, water and marine resources while supporting our digital economy
12 September 2018
Dr Minchin will outline the important work done by the Environmental Geoscience Division and its impact on everyday Australians.
Science and Technology in Indonesian Disaster Management: Ten Years of Indonesia - Australia Collaboration
05 September 2018
Science and technology has a significant role to play in modern disaster management. This talk will highlight how a ten year Indonesia-Australia partnership has deployed science and technology to strengthen Indonesian disaster management systems and practices.
SHRIMP: a time machine at Geoscience Australia Our geological past providing resources for a prosperous future
29 August 2018
There is a time machine at Geoscience Australia! The Sensitive High Resolution Ion Microprobe (SHRIMP) is a $5million mass spectrometer that measures the age of rocks. This talk will provide an overview about the achievements this machine has contributed to over the past 10 years, and its importance for future exploration opportunities.
The seven rocks that made Australia - the geology that has shaped our economy and society
22 August 2018
This talk reviews the last 4 billion years and looks to the future to identify the key geological events that have influenced Australia's economy and society. Pilbara Banded Iron formations and Permian coal measures are obvious choices, but what others would you choose?
Positioning & Community Safety Division's work program is all about outcomes benefitting Australians in a range of ways from information on natural hazards through to accurate location information. In addition, we provide support to the programs' of other parts of GA.
The Global Geodetic Reference Frame (GGRF) is a framework allowing users to precisely determine and express locations on the Earth, and to quantify changes of the Earth in space and time. This Presentation will detail the UN Global Geospatial Information Management (UN-GGIM) initiative to enhance the accuracy and sustainability of the GGRF.
Face to Face SAGE Data Release
01 August 2018
The SAGE team have collected a large amount of data for the Bronze Application- so far we are seeking your input on what this shows. Come along and see the extended data set in one sitting and ask questions about the assumptions in collection and presentation.
OneGA Showcase of Digital Innovation
25 July 2018
Leaders from the Digital Science and Information Branch at Geoscience Australia will showcase what their teams have achieved over the last six months. Come and see the progress made on Digital Products being newly Developed or Enhanced, the progress of our Data Strategy, advances from the Informatics team and more.
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.
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.
