[NEW RELEASE] The second edition of our Groundwater Sampling and Analysis field guide is now available 📔🔬! The comprehensive guide draws together information on drilling methods, bore construction, sampling equipment and sampling methods for groundwater analysis, including standard sampling protocols we have used over the last decade. These protocols aim to provide consistency for the acquisition of accurate, repeatable and comparable groundwater datasets and provides confidence in their analysis and interpretation. Monitoring groundwater is integral to understanding groundwater systems and aids effective management. By sampling and analysing groundwater on a regular basis we are able to understand and monitor changes to groundwater systems. In addition to its application for groundwater monitoring, the guide will assist sampling and analysis for the carbon capture and storage and mineral exploration, including for critical minerals.

🙌 The latest AusAEM survey is done! The NE QLD AusAEM survey covered 28,679 line kms at 20 km spacing - a huge amount of NE QLD. It will be an incredibly valuable dataset, filling in a large gap in the current national AusAEM coverage. Data will be released in coming months after quality assurance has been completed. Airborne electromagnetics (AEM) is a non-invasive testing technique that can measure variations in the conductivity of the ground to a depth of several hundred metres. AusAEM data and derived products are used to map the thickness and character of sedimentary and regolith cover. The survey includes the Adavale Basin and these data will aid in subsurface geology interpretations for groundwater, minerals and energy resource mapping. Preliminary data from the Peak Range Domes and Burdekin Basin has already generated interest. Learn more 👉 https://bit.ly/3i2dV7D. 📷 Area covered by the NE QLD AusAEM survey. The survey was funded via the Queensland Government’s Queensland Resources Industry Development Plan, with contributions from the Commonwealth Government’s Data Driven Discoveries program and Resourcing Australia’s Prosperity initiative. #AusAEM #ResourcingAustraliasProsperity

🌏 The Philips (Pilkington Jackson) globe is a historically and scientifically significant item for the Australian geological community and we are beyond excited to welcome the globe to its new home in our public spaces. With thanks to the ANU Research School of Earth Sciences for its donation, the work of Dr Mike Rickard and his numerous geology students, who hand painted the geological boundaries on the globe, will be preserved to inspire future generations. We welcome you to drop by and visit during our opening hours to see the story of plate tectonics and the link to the work of the National Earthquake Alerts Centre.

🛰️🌏 From auroras and geomagnetic storms that light up our skies to satellites and Earth observations that help us bring the benefits of space down to Earth... the Fuzzy Logic Podcast is back, and this one is out of this world! Our experts David Hudson, Medhavy Thankappan and Eloise Birchall joined Broderick to talk about the work we do in space, and how we are harnessing the power of space technology and long-lasting partnerships to tackle Australia's biggest challenges. Wrap up your #EarthScienceWeek with a dose of #Earthscienceeverywhere and tune in https://bit.ly/3A7KJIu 📷 Aurora Australis captured near Belconnen, ACT by local photographer @Palndrumm, 11 October 2024.

🙋Did you know the Australian tectonic plate is moving northeast about 7cm a year? This is the main cause for the 100 earthquakes of magnitude 3.0+ Australia experiences each year on average. ⚠️ Even though Australia doesn’t get a lot of big earthquakes they can and do happen. We also like to travel, and many popular destinations are in #earthquake zones, remember #EarthScienceEverywhere, including #earthquakes... 📚To share some #EarthScience earthquake facts, we chatted with earthquake scientist Dr Tamarah King about what to do if you experience an earthquake and how to stay safe during a ground shaking event – no matter where #onEarth you are. 🌏 Have you ever experienced an earthquake? Tell us about it in the comments or share an awesome Earth Science fact with us like Tamarah’s awesome #EarthScienceWeek fact at the end! #greatshakeout

🗺️ Our ‘Australia-wide 3D Density and Magnetic Susceptibility Models’ release is now available! By producing and recombining 235 individual inversion models of constrained gravity and total magnetic intensity data we’ve created two seamless crustal-scale 3D model of Australia. Covering onshore Australia in unprecedented detail these models give a clearer indication on the distribution of dense and magnetic materials under the Earth’s surface. They also provide insight into Australia’s geological structure and highlight regions of potential resource interest due to their anomalous physical properties and association with mineral systems. Applying this data in new ways has given us new information and helped develop other products such as our Iron Oxide Copper-Gold Mineral Potential Maps. Access the report and models here to investigate them for yourself 👉 https://bit.ly/4eIkW8Y 📷 Perspective view of the recombined density model showing the portion of the model within the undifferentiated crust which has a density > 2.9 g/cm3.

❄️ Thanks for dropping by, Australian Antarctic Science Council! We loved digging into some of the Antarctic treasures we have stored in our repository with you. We lead Earth science activities as part of the Australian Antarctic Program and have amassed a wonderful Antarctic collection over the years. The information we are able to gather from the collection is invaluable. This week, we showed the Council members one of the nearly 200 marine sediment cores from the collection, plus a few of our rocks and fossil specimens. Our repository holds samples collected from the icy frontier going back to the 1950s, and our library has first-hand writings from Antarctic field notebooks, some as early as the 1940s! Earth science is vital to Australia’s objectives in the Antarctic. The data and analysis from our experts inform decisions on the sustainable management of the Australian Antarctic Territory and adjacent marine environment. We map and characterise ice-free areas and the seabed to identify past-ice sheet movements, pathways for warm water incursion under ice sheets, high-value habitats and areas vulnerable to human impacts. Our scientists are at the forefront of Antarctic Earth science. We are always eager to share the insights that we develop through our work in Antarctica. The Antarctic Geoscience Portal makes it easy for scientists to access and study our samples and data, even if they are not able to visit Antarctica in person.

Congratulations to Eloise Birchall for your hard work and dedication to #EarthScience and leading an inclusive culture within the #earthobservation community. The Earth Observation Australia Inc. Community has recognised Eloise for her Early-Career Contribution to the Development of the Australian Earth Observation Community and its capabilities. Eloise was highly commended as someone who has worked in Earth observation for 5 years or less, and already made a large impact to the community. Eloise’s efforts to encourage people into the field through science communication and education, and her work championing diversity and inclusion hugely contributes to #EarthScience and our culture at Geoscience Australia. Thank you, Eloise 👏

After 8 years pushing the frontiers of science and forging a world-leading foundation of precompetitive geoscience through our Exploring for the Future program, we’re excited to deliver the #ResourcingAustraliasProsperity initiative. The landmark initiative, using innovative data, research and analysis, will accelerate the discovery of the resources necessary for Australia’s transition to net zero and inform sustainable management of our natural resources. The 35-year program will deliver nation-wide geoscience datasets, national resource assessments, including all of Australia’s critical minerals and strategic materials, and regional investigations across our national onshore and offshore boundaries. To help shape the first 10 years of the initiative, we are running a consultation period to ensure that our precompetitive geoscience, and its application, align with diverse stakeholder needs and objectives in the responsible management of Australia's future natural resources. ✏️ To help support our consultation process we need you to complete a short online survey 👉 https://bit.ly/3TZ41GE, by 𝟓𝐩𝐦 𝐀𝐄𝐃𝐓, 𝟏 𝐍𝐨𝐯𝐞𝐦𝐛𝐞𝐫 𝟐𝟎𝟐𝟒.
