b'Branch newsASEG newsAustralian Capital TerritoryIn news from the ACT and Geoscience Australia (GA) - the AEM survey for the Great Artesian Basin was completed in June, comprising 4500 line-km flown by SkyTEM. In newly developed probabilistic inversion code at GA, regional intake beds are clearly visible from the QC inversions on field data (see photo). GA will be in possession of all processed data by mid-August and the release is scheduled soon after. In other news, work on dynamic mantle topography done by GA in collaboration with researchers at the Australian National University and the University of Cambridge has been published in G3, available at https://doi.org/10.1029/2021GC009717. SkyTEM in action over the GAB and some of the preliminary dataIn a timely presentation, given our ongoing situation with COVID, Michelle Hendersons ASEG talk on Managing through (constant) change and uncertainty was quite the success with a hybrid online/in-person audience at GAs Raggatt theatre on 8 June. Michelles major point about how our brain works (or doesnt) in periods of prolonged stress was well taken. Self-care through exercise, mindfulness, a better diet and regular work breaks, though seemingly obvious, go far in allowing us to think creatively, avoid burnout and make better decisions.Anandaroop Ray actpresident@aseg.org.auNew South WalesASEG NSW was getting into the rhythm of 2021; the committee was organising in- Michelle Henderson presenting to the ACT Branchperson monthly meetings (see summaries below for the May and June meetings), we made the successful switch to pizzasBadlands, to explore the possiblePatrick Makuluni (UNSW), Tilting of the as the light refreshment on offerwhichrelationships between the influencesAustralian continent: New evidence from may, or may not, have contributed toof climate change and tectonics, to thethe subsidence and deposition history a slight uptick of in-person attendees,rivers course and dynamic topographyof the Northern Carnarvon Basin.
