The Cenozoic landscape evolution in southwestern North America Proposed mechanisms for the Cenozoic landscape evolution in southwestern North America (SWNA) include crustal isostasy, dynamic topography, or lithosphere tectonics, but their relative contributions remain controversial. Recently our study 'Coupled
Seismology 2022, IN A NUTSHELL 2022 was an exciting year for deep Earth and planetary sciences communities. I summarize our contributions, discoveries and advances in publications from 2022
Geophysics William Edward (Will) Featherstone Professor Will Featherstone passed away on 13 May 2022 in Perth after a brief illness. He was 54 at the time he died but he had behind him a thirty year research and teaching track record and over twenty years as full Professor in Geodesy.
Seismology Lighting Up Dark Fibre for Seismic Imaging Distributed acoustic sensing, or DAS, is a newly developed passive seismic technology that can transform telecommunication fibre-optic cable into linear arrays of ground motion sensors.
Geology 100 days of geoscience I plunged headfirst into a commitment to post a picture from my research once a day for 100 days, beginning on the first day of semester two, 2021.
Geophysics Victorian Earthquake Round-up Last week's Woods Point earthquake in Victoria was a quite a surprise for most Australians outside the geophysical community and even among Earth scientists, an event of this magnitude was unexpected.
Seismology Australia surprised by moderate quake, but rumbling is not unusual On the morning of September 22, a magnitude-5.9 earthquake struck approximately 130 km northeast of Melbourne. Seismic waves were felt in Melbourne, Canberra, Sydney and Adelaide, and as far south as Tasmania.
Geophysics Australian Seismometers in Schools - Noise monitoring dashboard How we built a simple dashboard using Github actions with open source software and openly available (FAIR) data.
Education Lava Lamps & Thermochemical Convection Hands-on experiments explore the details of thermochemical convection. Build your own Lava Lamp and learn why the continents don't get sucked down into the deep Earth.
Geophysics Seeking The Truth Hidden In The Earth’s Lowermost Mantle If we were lucky to travel to the Earth’s centre, perhaps as part of an international crew of terranauts chosen to observe and investigate our planet’s interior…
Geophysics New Reference Earth Model: CCREM In these one-dimensional (1D) models, the Earth (or, as a matter of fact, any other planet) is divided into kilometres thick spherical layers, just like an onion on a much smaller scale
News Discovery Early Career Researcher Awards in Geoscience, 2022 ARC Chief Executive Officer, Professor Sue Thomas, has welcomed the approval by the Minister for Education and Youth, the Hon Alan Tudge MP of $83 million in funding through the ARC’s Discovery Early Career Researcher Award (DECRA) scheme.
Geohazards How earthquake science supports decision-making in the ancient continent Australian earthquakes pose a high consequence – low likelihood risk that is widespread across the continent but is often not well characterised for some of Australia’s most important infrastructure.
News Australian Academy of Science Statement on Declining Funding for University Earth Science Members of the National Committee for Earth Sciences of the Australian Academy of Science are deeply concerned by the systematic reduction in staff members in geosciences departments over the last year in Australia.
Geology Metals for an Electrifying Future The transition to a low-carbon / below-zero-emissions future presents many challenges for the industries "behind the scenes" that provide the raw materials for the innovative technical solutions that will become a part of our everyday lives.
News Australian Research Council Future Fellowships 2021 One hundred researchers will receive Australian Government funding to focus on finding solutions for key industry challenges and training the next generation of researchers under the ARC Future Fellowships scheme.
AuScope Building Australia's Downward Looking Telescope AuScope is building Australia’s Downward Looking Telescope, a sophisticated and integrated research infrastructure system that helps researchers address national decadal geoscience challenges. Here is all you need to know about the DLT.
AuScope Distributed Acoustic Sensing in Australia's Downward Looking Telescope Seismic waves are being recorded in more detail than ever before. In this latest collaboration with the NASA Deep Space Network (DSN), researchers from The ANU and AuScope’s Earth Imaging and Sounding Program explain Distributed Acoustic Sensing (DAS) infrastructure .
Geophysics Probing the Australian-Pacific Plate Boundary: Macquarie Ridge in 3D (Updated) A team of Australian researchers are about to set off on a landmark voyage to discover more about the Earth beneath our oceans, and what triggers underwater earthquakes. Read live updates of the cruise as they go — both personal reflections and scientific background to the cruise.
Editorial Australian Earth Science facing a very uncertain future (updated) Earth Science - everyone should know a little, but it is also important for Australia to have access to deep expertise.
Geodynamics High mantle seismic P-wave-speeds as a signature for pancake-like flow in the upper mantle Buoyant material rising in the Earth's mantle is expected to spread out when it reaches the base of a tectonic plate like pancake batter dropped into a pan.
Geology Photos from the field: the stunning crystals revealing deep secrets about Australian volcanoes This isn’t a painting or a stained-glass window — it’s a microscope image of light shining through the Earth’s mantle (image from the author, Heather Handley)
Geophysics Unlocking the secrets of the sub-Antarctic underground Staff from the Australian Antarctic Division are now installing seismometers on the Macquarie island as part of the "Macquarie Ridge in the 3D" project.
Geodynamics A response to Gillian Foulger's argument against mantle plumes on Oliver Strimpel's podcast Mantle plumes are the best explanation we have for much of Earth's intraplate volcanism but some remain doubtful despite 50 years of rigorous testing.
Geodynamics Geodynamic models link enigmatic intraplate volcanism in Eastern Asia to subduction history and upper mantle upwellings In Eastern Asia, Jurassic and Cretaceous intraplate volcanism and magmatism differ in their spatial distribution and composition. A combination of plate kinematic and geodynamic models provides clues for their causes.
