Excited to share our new paper in @IOPenvironment modelling the outcomes of different grazing land management under #ClimateChange in northern Australia. Lots of trade-offs, but some balance is possible between environment and production. @SciMelb @brettabryan @j_r_rhodes

We're so excited for the Howitt Lecture 2024! Join us and @RoyalSocietyVic on Thursday 27 June at 6pm to see Dr. Gresley Wakelin-King presenting on "Australian Desert Rivers: So Cool, So Dry, So Dynamic". Tickets selling quickly, get yours today!: https://t.co/5PtKwTrc4e

I'm honored to receive the Martin Aitken Student Poster Awards at #ISA2024Melb. This marks my first poster award in the field of Archaeology🏅🎉 I'd like to express my gratitude to the committee members for their recognition and support🎉🙏🏻

Proud supervisor! @SainiSamim gave a brilliant talk at the @ARCAS_news 42nd ISA on her @SciMelb PhD research unravelling the complexity of volcanism in the Turkana Basin🌋 P.s. I also enjoyed presenting a poster on our work applying Ar-Ar geochronology to archaeological problems

Join us on Thursday May 23 to hear all about SAND DUNES ON MARS(!!!) from @_algunn 5.30pm in Carlton - see you there! Details here: https://t.co/5PtKwTrc4e

It's been a little dusty here in Jezero Crater lately, but that's to be expected... we're in the heart of Martian dust season! How is it going for you, @MarsCuriosity?

Very proud of @SainiSamim's first paper as part of her @SciMelb PhD! Saini (painstakingly) evaluated the best approach for LA-ICP-MS analyses of tiny volcanic glass fragments, demonstrating how useful this can be for fingerprinting eruptive layers🌋🔬 OA🔓 https://t.co/uTTjjuYntX

We’re hiring a new Beamline Scientist! Come work with me @ausynchrotron - it’s super fun! Happy to answer any questions about the role - just shoot me a DM. https://t.co/JzKRNgNSnx

My first day @UniMelb. I am very excited to be joining SGEAS and to be part of the Melbourne geo community again. Today was also my Dad’s last day in his current position in the same school

The Academy has awarded Dr Andrew King (@UniMelb) the Anton Hales Medal for his contributions to climate science. The medal underscores the vital role of Earth scientists and their impact on understanding our planet’s dynamics and natural processes.

We're delighted to award the Selwyn Medal for 2024 to Dr Kevin Hill! Kevin uses new technologies and techniques in industry, which have resulted in major contributions to building knowledge in tectonic and structural evolution of basins. Huge congratulations to Kevin!

New postdoc opportunity! Position working with me and @21CWeather on high-impact weather in a warming world! Applications close 23rd April.

CALLING ALL EARTH SCIENCE STUDENTS! Applications close on March 29 for GSA’s Endowment Fund Awards! Learn more and apply:

I may have missed posting on International Day of Women in Science this week. Lucky we science everyday! Stromatolite treasure hunt this week in Western Vic.

Last January, I noticed something peculiar in my 2yo’s bedroom that - after a year of obsessive reporting - led me to a profound cosmic revelation about what’s even possible in our universe. A 🧵.
