💪 A superpower of the Southern Ocean is taking up heat and carbon from humans and slowing the rate of global warming, by exchanging heat and carbon between the atmosphere and the deep ocean. 🔄 The freeze-and-melt cycle of sea ice drives this exchange by changing water density and acting as a pump.

🌀The stratospheric polar vortex is a belt of high-speed cyclonic winds around 12-20km high over the poles. When temperatures in the stratosphere – which contains the ozone layer – start rising in the southern spring, the ozone hole over the Antarctic grows. 2025 ozone: @copernicusecmwf.bsky.social

🌏 Why Antarctica matters to Australia 🛝 Abrupt changes in the Antarctic environment 🌊 Antarctica and sea-level rise AAPP & @antarcticsciaus.bsky.social have sent these policy briefs to hundreds of politicians and policymakers around Australia.

Q: What happens when #Antarctic summer sea ice hits record lows in 2017, 2022, 2023, 2024 and 2025? A: aapp.shorthandstories.com/a-world-with...

💎 What does the colour of icebergs have to do with storing carbon in the ocean? Prof Delphine Lannuzel is on board RSV Nuyina in East #Antarctica for the Denman Marine Voyage #DMV. @utas.edu.au | @antarcticsciaus.bsky.social | @arcsaef.bsky.social | AAD 🌊 youtu.be/_3ZGE9P0Qg0

🌨️ Clouds over the cold Southern Ocean are different from elsewhere. Here they're seeded not by aerosols from land, but from the ocean—and even life itself. Chelsea Bekemeier, on the Denman Marine Voyage #DMV in East #Antarctica, explains. Full video at youtu.be/nGpVrJQkIaE

🐚 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

Gives me the giggles

They’re getting under my skin 🌊🤗

Here's the latest 'Southern Signals' about our science in #Antarctica and the @thesouthernocean.bsky.social ➡️ createsend.com/t/j-39BDED69... Our best wishes to you for the festive season and a happy new year, especially to scientists and crew working away from home, on the ice and at sea.

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. Our @magic.bas.ac.uk colleagues have illustrated A23's super circuitous 2024 journey via satellite imagery ⬇️ www.bas.ac.uk/media-post/w...

From the bottom up—I’d like you to meet one of my best sides 🧵 check this thread

Deeply beautiful

Some people consider me cold and remote. But I’m just getting warmed up. 🌊 Stay with me folks. @utas.edu.au @arcsaef.bsky.social @antarcticsciaus.bsky.social
