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

“A lot of nations are sort of going backwards just at a time when we really need to advance our understanding of Antarctica.” - @deformedearth.bsky.social on Antarctic research publication trends, on the ABC’s 7:30 ⬇️ @utas.edu.au @antarctic.bsky.social www.abc.net.au/news/2025-08...

Join the Denman Glacier geology 🪨🌋⛏️ team for an evening at the pub this Tuesday! We will be bringing our rocks from Antarctica, the venue has the drinks, all that is missing are your questions! #Beakerstreet 🧪❄️🌊 more information: tickets.beakerstreet.com.au/Events/SCIEN...

"That is a crisis in terms of our ability as a nation to do the work we need to do to inform the policymakers, but also just to show that we take Antarctica seriously." - Director @deformedearth.bsky.social on the approaching funding cliff for #Antarctic research ⬇️ www.abc.net.au/news/2025-06...

"The rocks that the glacier sits on impact the way it behaves, the heat that’s coming through the crust impacts the way that glacier behaves." WATCH: Professor Jo Whittaker (IMAS) and Dr Karin Orth (UTAS) on what the Denman region's ancient rocks can tell us ⬇️ #DMV www.youtube.com/watch?v=mn4Q...

The best part about our icy research is sharing it! Our calls with schools were certainly a highlight of the Denman Marine Voyage! 🧊🧪⚒️🪨🚢

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...

Finishing the #Denman Marine Voyage with more outreach I invited students from my old high school in Northern Germany to come on a virtual tour of RSV Nuyina. Through the @antarcticsciaus.bsky.social school outreach program, 96 year 11 students learned about the science we do on DMV: 🌊🧊🇦🇶🧪🦭🌡️🐙☁️

🐚 AAPP PhD student @utas.edu.au Nia Riengchan studies how acidification of the Southern Ocean affects the shell-building of small planktonic snails called 'sea butterflies'. Now, for the first time, she's able to watch their babies develop. 🌊 Full #DMV video at youtu.be/1fTlpTQTOOc 🎞️ P Harmsen/AAD

As the #DMV reaches its final days in #Antarctica, the last rock dredges are underway. This one retrieved "just three rocks, but all the same so that is very good!" - @hochmuth.bsky.social, pictured with Jo Whittaker. Follow our research teams on our #DMV #blog ⬇️ antarctic.org.au/dmv#dmvblog

The major role of phytoplankton in reducing carbon dioxide in the atmosphere is well established, yet the factors controlling phytoplankton growth are still not fully understood. The #DMV is a great opportunity to learn more, write Pauline Latour and team ⬇️ #blog antarctic.org.au/tiny-but-mig...

Being able to monitor the overflow of #Antarctic dense waters from the continental shelf to deeper open waters is critically important, but has long been a major challenge for scientists. New research from @matthisauger.bsky.social could be a game-changer ⬇️ antarctic.org.au/satellite-ob...

Yesterday was our last day in the sea ice. I was really lucky to have experienced this amazing landscape with its adorable wildlife in the last weeks. We had a very successful science program in areas of East Antarctica never studied before 🌊 🧪 Goodbye Antarctica 👋🇦🇶🐧 #DMV

The #DMV has transited east and west of the Denman Glacier and the Shackleton Ice Shelf, and one side is markedly more biologically productive than the other. How to find out why? Here's Delphine Lannuzel and Pauline Latour, with @antarctic.bsky.social ⬇️ aappartnership.org.au/all-part-of-...

These rocks were retrieved from the first dredge, deployed to a water depth of 2700 metres on the steep eastern slope of the Eastern Bruce Rise. Further dredges are planned, including to features that may be extinct underwater volcanoes. @utas.edu.au 📷: Katharina Hochmuth / Delphine Lannuzel

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-...

What lies beneath 🌊 Dramatically-reduced sea ice cover in front of the tongue of the Denman Glacier has allowed a rare exploration opportunity on the #DMV Here's @hochmuth.bsky.social on the mapping of the seafloor in this incredible unchartered territory ⬇️ #blog antarctic.org.au/denman-glaci...

Sea ice has appeared in a variety of shapes and forms on the Denman Marine Voyage "...from newly formed ice to thicker, older floes that shake the ship when we collide with it." Find out more in our latest #DMV #blog post from @claire-y.bsky.social, 'Into the ice' ⬇️ antarctic.org.au/into-the-ice/

The glamourous life of a trace metal chemist: Delphine Lannuzel and Robin van Dijk 'milking' bottles of seawater from the second #DMV trace metal rosette deployment. Protecting the integrity of the samples is a tricky business and every effort - even with the air, is made to prevent contamination.

How and why, we name geographical landmarks is and has always been an important part of scientific expeditions. So who is the inspiration behind the Denman Glacier? There's one woman more than deserving, writes @hochmuth.bsky.social in our latest #DMV blog post ⬇️ antarctic.org.au/hey-sir-maws...

Hey Bruce Rise, how have you been in the last year? Bruce Rise is a fascinating continental fragment, which wedged itself between Australia and #Antarctica during the opening of the Southern Ocean. We visited in 2024 on #RVPolarstern and are now back on #RSVNuyina as part of the Deman Marine Voyage.
