It's always a celebration when a PhD student publishes their first paper! Congratulations John Bright Ayabilah, who came from Ghana to @imas-utas.bsky.social @antarcticsciaus.bsky.social to work on how modes of climate variability affect the mass of the Antarctic Ice Sheet 1/2 ❄️🧪

🌊 New paper in @natclimate.nature.com: 'Mapping tipping risks from Antarctic ice basins under global warming', by @pik-potsdam.bsky.social "Marine-based sectors in East Antarctica, representing ~5 m of potential sea-level rise, are at risk of losing stability at 2–5 °C." ▶️ rdcu.be/e5bQS

“The future of Antarctic science is already on board. And it is being led, confidently and collaboratively by women." – ACEAS Chief Investigator and COOKIES Chief Scientist Dr Linda Armbrecht (IMAS/UTAS) and Joline Lalime, Sea2SchoolAU. Happy International Day of Women and Girls in Science 2026!

🌊 An important new study led by ACEAS PhD researcher Annika Oetjens from @imas-utas.bsky.social at @utas.edu.au shows the Southern Ocean may be storing 40 to 60 per cent less carbon at certain depths than many climate models assume. Learn more ▶️ antarctic.org.au/southern-oce...

🌊 The ocean may look calm, but beneath the surface moves a powerful engine that redistributes heat, carbon and nutrients around the world. Our new COOKIES blog article breaks down how global ocean dynamics work – and why they matter for our climate. Learn more ➡️ antarctic.org.au/cookies-blog...

🌏 Better models = better climate predictions. A new paper led by ACEAS PhD researcher Claire Yung (ANU) shows how a refined equation used in ocean models can significantly improve the accuracy of Antarctic ice shelf melt predictions. ➡️ antarctic.org.au/new-model-co...

🚢 COOKIES voyage delivers record‑breaking core for RV Investigator A huge milestone for the RV Investigator COOKIES voyage – the successful recovery of a whopping 20.5‑metre sediment core, now officially the longest core ever retrieved in the vessel’s history. ➡️ antarctic.org.au/cookies-blog...

New paper: we show that variability in the Zonal Wave-3 mode - an atmospheric pattern made up of three pairs of cyclones and anticyclones circling the Southern Hemisphere - does influence the formation and export of dense waters around Antarctica over multiple years.

🧊 A great new feature piece in @physicstoday.bsky.social by ACEAS CIs Dr Catherine Vreugdenhil and Dr Bishakhdatta Gayen from @unimelb.bsky.social that unravels the mysteries of Antarctic ice‑shelf melting. Read it now: physicstoday.aip.org/features/unr...
