Geophysics and Computational Analysis

The Geophysics and Computational Analysis group within the CET makes significant and valued contributions to the use of geoscientific data across the industrial and academic spheres. Our vision is to improve the efficiency, accuracy and consistency of the display and analysis of geoscience data across the mining, exploration, and other geoscientific communities.

    Colour Maps for Relief Shading

    Relief shading can be a very effective way of presenting spatial datasets. By treating the data as if it is a 3D surface and generating shading corresponding to the surface being ‘illuminated’ from some direction, we can use the eye's innate ability to interpret sha...

    Chasing Footprints of an Elusive Quarry

    Remobilization of metals during post-deposition hydrothermal alteration of magmatic sulfide ores has the potential to produce distinct haloes far greater in scale than the source ore body. Recognition of such dispersed signatures may dramatically enlarge the detectable footprin...

    3D Crustal Architecture and Mineral Prospectivity of Under-Explored Terrains in Western Australia

    Working closely with the Geological Survey of Western Australia (GSWA) and funded by the WA State Government's Exploration Incentives Scheme, a team of reseachers at CET has recently completed a major study of the prospectivity of key greenfields terrains in Western Australia (...

    A Social License to Undertake Research

    Modern research science is a capital-intensive industry. Scientific resources and agencies are concentrated in wealthy developed nations with the economic and infrastructure base to support such fundamental endeavours. Nature, however, respects no such distinctions - and we com...

    The ongoing search for Hadean crust on Earth

    The familiar concentric layer cake structure of the Earth depicted in textbooks formed within a few hundred million years of the accretion of the planet. This is when the metallic core segregated, the oceans condensed, the atmosphere outgassed and the first rocky crust formed....

WA Information Technology & Telecommunications Alliance (WAiTTA) gala awards dinner

by Daniel Wedge | Jul 04, 2014
The annual WA Information Technology & Telecommunications Alliance (WAiTTA) gala awards dinner was held on 20 June at the Perth Convention and Exhibition Centre. These awards recognise outstanding innovations in the ICT sector developed in WA in the last year. CET Research Associate Tom Horrocks was one of five honours students shortlisted from WA for the student project award for his Honours thesis in 2012/13, entitled "From Data to Strata: Recognising and Correlating Coal Seam Patterns Across Wireline Logs".
The annual WA Information Technology & Telecommunications Alliance (WAiTTA) gala awards dinner was held on 20 June at the Perth Convention and Exhibition Centre. These awards recognise outstanding innovations in the ICT sector developed in WA in the last year. CET Research Associate Tom Horrocks was one of five honours students shortlisted from WA for the student project award for his Honours thesis in 2012/13, entitled "From Data to Strata: Recognising and Correlating Coal Seam Patterns Across Wireline Logs". This project was supervised at CET by Associate Professor Eun-Jung Holden and Assistant Professor Daniel Wedge, and by Darren Christophersen from Conducive. Tom developed a fast and objective method that used machine learning for classifying intervals from downhole geophysical logs and then using pattern matching to correlate lithologies from multiple drillholes. Recently, this work has led to the development of CET's Wireline Spelunker (link to: http://www.cet.edu.au/news-and-media/news/news-details/2014/05/12/cet-staff-and-students-participated-in-the-inaugural-unearthed-hackathon) which has received much industry attention.

The awards dinner was well attended by about 450 representatives from academia and local and national ICT companies. The night started well when the door prize was won by Eun-Jung Holden who happily took home six bottles of wine. In the end, the student prize was won by UWA electrical engineering PhD student Stuart Speidel. Other awards were given in the fields of resources industry based ICT projects, new IT products and systems on the market, and government systems development.
