🪨 The project will combine new geological observations with numerical modelling to quantify past ice sheet retreat during the previous warm Pliocene epoch (3–3.3 million years ago), which is an analogue for climatic conditions expected within decades. @utas.edu.au | @imas-utas.bsky.social

🌏 Led by ACEAS Chief Investigator Associate Professor @jaxhalpin.bsky.social, the team includes Dr Taryn Noble, Associate Professor Alan Aitken, Dr Jacob Mulder, and Dr @hochmuth.bsky.social.

🌍 Last week, 140+ Antarctic scientists came together in #Hobart for our ACEAS Research Forum 2025 to share the latest research and insights about the climate risks emerging from #Antarctica and the #SouthernOcean. Read more: antarctic.org.au/aceas-resear...

🦠🧪 Congratulations to our biogeochemistry team on winning an Australian Research Council (ARC) Discovery Project grant to iron out wrinkles in climate models. ▶️https://aappartnership.org.au/unlocking-how-iron-shapes-ocean-life-and-climate/

How vulnerable is East Antarctica’s ice in a warming world? 🧊🌍 Thrilled to be awarded #ARC funding with my stellar collaborators! We will explore geological archives that record how the ice sheet reacted to past warm periods — and what that could mean for our future. @antarcticsciaus.bsky.social

What's the future for Antarctic sea ice? Next Tuesday (11th November I'll be giving a free lunchtime talk at TMAG on @antarctic.bsky.social @imas-utas.bsky.social efforts to answer that very question. You can register here: url.au.m.mimecastprotect.com/s/UVHnCE8kD7... #hobart #utas #antarctica

Ever wondered what lies beneath the fastest melting glacier in #Antarctica? Read on…. 🔥New paper just out🔥led by my brilliant @bas.ac.uk colleague Tom Jordan: www.nature.com/articles/s43... Combining #geology & #geophysics, we discovered a huge granite beneath Pine Island Glacier! 🧵 below…. 1/n 🧪❄️🥼

Wrap your hands around a 3 billion year old piece of Antarctica! I’ll see you there 🤘

❄️ A landmark new study has revealed that glaciers on Australia’s remote sub-Antarctic Heard Island are shrinking at an accelerating rate due to rising temperatures and climate change. tc.copernicus.org/articles/19/... @andrewmackintosh.bsky.social @heardislandgov.bsky.social @arcsaef.bsky.social

Here for the ice cold diplomacy 🐧

Great work by our colleagues Stewart Jamieson and Guy Paxman: "We have been using satellite data to map an ancient river landscape beneath the East Antarctic Ice Sheet:. The landscape has been frozen in time for up to 34 million years." ⚒️🧪 www.nature.com/articles/s41...

"I am optimistic about fostering stronger India–Australia collaborations in Antarctic science and look forward to more opportunities like this in the future." - 2025 @scar-antarctic.bsky.social INSTANT Fellow Dr Devsamridhi Arora on her recent @utas.edu.au visit ⬇️ antarctic.org.au/introducing-...

Discovery of microcontinents in the Kerguelen Plateau region of the Southern Ocean! 🌊 🌏 New OA research led by @imas-utas.bsky.social @antarcticsciaus.bsky.social PhD student Jeremy Asimus out now: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Excited to be amongst geo friends at Uni Adelaide to give a talk on Antarctic mountains & learn from some of the best 🤩

the only good king is the king parrot 👑

Very proud of my #IODP shipmates for spearheading this amazing paper on our new data from #Exp395. We are looking at the onset of deepwater formation in the North Atlantic and its relation to Greenland‘s ice sheet. ⚒️🧪⛰️🪨🚢🧊 www.nature.com/articles/s41...

New study of an ancient collision zone reveals origins of enormous mountain range, hidden beneath the East Antarctic ice sheet and central to Earth's tectonic history ♨️ - from @jaxhalpin.bsky.social and Nathan Daczko @imas-utas.bsky.social | Macquarie Uni theconversation.com/antarctica-h...

🏔️ "The Gamburtsev Mountains are similar in scale and shape to the European Alps. But we can’t see them because the high alpine peaks and deep glacial valleys are entombed beneath kilometres of ice." — @jaxhalpin.bsky.social @utas.edu.au & Nathan Daczko ▶️ theconversation.com/antarctica-h...

The first rock dredges of the #DMV have delivered - and many rocks found seem to have come from beneath the vast Denman Glacier. There are signs the region might be a particularly warm area geothermally, and this can impact on the base, writes Jo Whittaker ⬇️ #blog antarctic.org.au/revealed-in-...

On the edge of #Antarctica, 60 scientists aboard RSV Nuyina are researching the impact of climate change on the fastest-melting glacier in the eastern part of the icy continent — ABC News with @utas.edu.au, @arcsaef.bsky.social, AAD and @antarcticsciaus.bsky.social ▶️ www.abc.net.au/news/2025-04...

Look how happy Taryn is with her seafloor sediment!! ⚒️🌊🧪 It holds keys to understanding past climate and ice sheet behaviour in the Denman Glacier region of Antarctica

🧪🌊🧵 Despite having his job at NOAA terminated @zacklabe.com has still brought his visualisations that show the alarming recent trend in Antarctic sea-ice extent up to date. zacklabe.com/antarctic-se... 1/2

Two more sleeps until departure day! Here's most of the 47 scientists from AAPP @utas.edu.au & @antarcticsciaus.bsky.social leaving on the two-month Denman Marine Voyage (5000km south to East #Antarctica) with AAD and @arcsaef.bsky.social this Friday. 🌊 Follow them at aappartnership.org.au/DMV/

Join scientists from @utas.edu.au and @antarcticsciaus.bsky.social in East #Antarctica as they plumb the depths of the ocean under an ice shelf with a power tool, a long drill, lots of line—and plenty of stamina.

First post on BlueSky to mark the end of my Antarctic fieldwork in Queen Maud Land working with @andrewmackintosh.bsky.social and some other wonderful scientists at @arcsaef.bsky.social. Overall, trip was hugely successful, with some exciting science to come. 1/4

Christmas might be over, but the gifts keep coming for the @antarcticsciaus.bsky.social geo team! 🪨🎁 Today @icylava.bsky.social took delivery of new rock samples from Gaussberg - East Antarctica’s only exposed volcano 🌋 (even geophysicists were excited, right @hochmuth.bsky.social 😉) ⚒️🧪

A23a has finally escaped the vortex! 🏊‍♀️🌀 The biggest iceberg in the world is on the move again after a casual half-year sabbatical spent spinning in circles.
