🌊 1/ A robotic float has measured the temperature and salinity from parts of the Southern Ocean never sampled before — underneath massive floating Denman and Shackleton ice shelves in East #Antarctica.

⤵️⤵️ Double dip: For the second winter in a row, the extent of Antarctic sea ice has been exceptionally below average — and has just set a new record low for this time of year.

The @_SouthernOcean is renowned for having the cleanest air on🌏
But until now scientists haven't understood why🤔
New research in @Nature_NPJ shows how clouds & rain play a crucial role in "scrubbing" the air clean.

1/5🩵 "The rhythmic expansion and contraction of sea ice is just like a heartbeat. Just as a change in our heartbeat affects our whole body, a change to sea ice around Antarctica affects the whole world." — animated satellite data 1978-2024 by @ACCESS_NRI, from @NSIDC via @NASA
Long lap: “like driving between Sydney and Perth three times, at a max speed of 20 kmh.” An epic #MISO voyage of 60 days and 12000 km on @CSIRO#RVInvestigator lands one of the most comprehensive datasets ever collected from the Southern Ocean.

“It looks as though the Southern Ocean is shifting gear but we don’t yet know where it’s heading and what that means for us. That’s where our research comes in.” — Nathan Bindoff of @Ant_Partnership at @UTAS_ in @GuardianAus

🌊 Did you know that the Southern Ocean is responsible for 50% of the oceanic uptake of CO2.
🌊 Major changes in phytoplankton in the Southern Ocean are linked to drivers of climate change, a study published in @NatureClimate shows.👇🏻

What makes the best address for an emperor penguin colony? Each year they return to the same areas of landfast ice – the sea ice attached to the #Antarctic coast – for a stable platform that lasts long enough for their chicks to fledge. But there’s more to it than that.
🌊🌏 "The Southern Ocean ... keeps our planet liveable. However, despite the efforts of long-term programs carried out by several nations, the @_SouthernOcean remains one of the most under-observed regions on our planet." — @drsianhenley@SOOSocean

At the #SOOSSymposium2023 300 experts from 25 nations met in Hobart to underscore the Southern Ocean's vital role in regulating climate.
@drsianhenley emphasizes the need for global collaboration to comprehend this crucial ecosystem, while @AmidgeAndrew highlights the Southern Ocean's influence on Antarctic ice melt and sea-level rise.
With changing conditions, funding and sustained research are imperative. Let's bridge observation gaps and ensure a sustainable future for our planet! 🌏

With what’s going down in #Antarctica right now, this is a critically important time to bring together hundreds of the world’s @_SouthernOcean scientists for the first-ever global meeting of @SOOSocean. We’re proud it’s in 🇦🇶 gateway @cityofhobarttas.

“To say unprecedented isn't strong enough”: as #Antarctic sea ice levels nose-dive, AAPP scientists warn @abcnews the natural likelihood of a winter like this is once in 7.5 million years.

'Southern Signals' is our quarterly science bulletin. Read the latest about our research on Antarctic sea ice and the Southern Ocean in the June edition.
Out now! ▶️ https://t.co/Qh6o0suIrP
For the first time in August, @SOOSocean will hold one of the world’s most important international scientific gatherings about an ocean central to the Earth system.
We look forward to welcoming #SOOSSymposium2023 to @cityofhobarttas next month!

The global ocean naturally stores about $3 trillion worth of carbon a year, about a third of the carbon we emit. Knowing how this free eco-service might change in the future may depend on understanding how tiny zooplankton eat.

The massive currents swirling around Antarctica are a crucial driver of the global network of ocean currents that transport heat, carbon, oxygen and nutrients around the world. How will this lifeline change on a warming planet?

🌋 One of Australia’s only active volcanoes is erupting! This remarkable satellite image on 25 May shows lava flows from Big Ben on Heard Island in the @_SouthernOcean. The summit Mawson's Peak is 2745m above sea level.
