On Monday 25 March, Prof Boris Gurevich, Curtin University, CSIRO, a SEG/ ASEG Honorary Lecturer spoke about, “Seismic attenuation, dispersion, and anisotropy in porous rocks: Mechanisms and models”, explaining the importance of modelling attenuation and dispersion of seismic waves in fluid saturated rocks. On Wednesday May 8 Matthew Zengerer from Gondwana Geoscience spoke about some work he had presented at an international conference a few weeks before;“Application of gravitational curvature analysis to structural domaining of geology.”We had Matt’s posters on display throughout the evening, which encouraged easy discussion. This talk was recorded and will be made available on the ASEG YouTube channel in the coming weeks. We have two National Geoscience Champions (as awarded by the Australian Geoscience Council in 2018) speaking in the next few months. Professor David Groves will speak on the evening of 20 June about“A holistic subduction/ metasomatized lithosphere model for orogenic gold deposits”, and Dr Marita Bradshaw on August 1 about“Australian petroleum exploration – a game for long term players.” As always, very happy to hear any feedback or suggestions at sa-ntpresident@aseg.org.au. Hope to see you soon at an ASEG event soon. Kate Robertson sa-ntpresident@aseg.org.au Tasmania There was a flurry of Tasmanian geophysical activity in March. Paul Winberry from Central Washington University presented“How Much? How Fast? Seismology’s role in understanding the future of Antarctica’s ice sheets”to a joint meeting of ASEG and GSA Tasmania Branches on the evening of the 21st. The cryospheric stage for Paul’s talk was serendipitously set less than a week earlier by Macquarie University’s Kate Selway and JP O’Donnell, who generously took time out of their Tasmanian holiday to give a joint UTas Physics/Earth Sciences seminar on“Adventures in (polar) magnetotellurics and seismic studies of the Antarctic Peninsula.” ASEG/SEG Pacific South Honorary Lecturer Boris Gurevich of Curtin University and CSIRO brought his presentation“Seismic attenuation, dispersion, and anisotropy in porous rocks: Mechanisms and models”to Hobart on 27 March. Twenty five members of a strongly interdisciplinary audience gained insights into fundamental interactions of seismic wave propagation and fluid flow. An invitation to attend Tasmanian Branch meetings is extended to all ASEG Members and interested parties. Meetings are usually held in the CODES Conference Room, University of Tasmania, Hobart. Meeting notices, details about venues and relevant contact details can be found on the Tasmanian Branch page on the ASEG website. As always, we encourage Members to also keep an eye on the seminar programme at the University of Tasmania / CODES, which routinely includes presentations of a geophysical and computational nature as well as on a broad range of earth sciences topics. Mark Duffett taspresident@aseg.org.au Victoria Autumn is generally a fabulous time to be in Melbourne. Events such as the family-friendly Moomba Festival, the extravagant Australian Grand Prix, the magic Melbourne International Comedy Festival and of course, last but not least, the sensational phenomenon of a technical meeting event of the Victorian Branch of the ASEG; all of which are testament to Melbourne’s temperament during the autumnal months. It was a noticeably frenzied period for the Victorian Branch as we showcased three rather contrasting and sometimes contentious (maybe even scandalous!), thought-provoking addresses to our Members. First cab off the rank was Professor Boris Gurevich, the SEG Pacific South Honorary Lecturer for 2019, making a tour stop in Melbourne on March 21 to greet a small gathering of zealous Members at the Kelvin Club. The Professor’s presentation, generously entitled“Seismic attenuation, dispersion and anisotropy in porous rocks: Mechanisms and models”, overwhelmed the reasonably behaved crowd with fluid mechanics and mathematics that was acutely foreign to those who were seen scratching their head after nodding in acknowledgment of having understood said concepts. Members certainly appreciated the ideas and some even got a giggle out of the term“squirt-flow”, lol. For our April Technical Meeting, we greeted Don Furseth, CEO of CRM GeoTomography Technologies. The meeting was the brainchild of Joe Cucuzza of AMIRA International, who broached the idea of having the VIC ASEG Branch jointly host a technical session.
