Tomorrow is World Penguin Day! 🐧

There are 18 species of penguins, five of which live in Antarctica and another four on sub-Antarctic islands, but nearly all penguins live in the southern hemisphere.

🕵️‍♀️Observations are key to unraveling the mysteries of our oceans!

A recent review in Nature Reviews Earth & Environment 🌈 highlights the enigma of the Southern Ocean's carbon cycle: Despite being iron-limited with low productivity in most areas, the Southern Ocean still manages to act as a…

👀Check out this ship’s-hull view of the seafloor.

🚢On a recent voyage to Mawson research station, 719 sq km of seafloor features, including shipping hazards, were precisely mapped for the first time using RSV Nuyina’s acoustic instruments.

“Extreme lows in Antarctic sea ice led researchers to suggest that a regime shift is under way in the ⁦⁦⁦⁦Southern Ocean⁩, and we found multiple lines of evidence that support such a shift to a new sea ice state.”—Will Hobbs, AAPP/University of Tasmania⁩ theguardian.com/environment/20…

In 1898, the crew of a pioneering Antarctic expedition found themselves trapped in sea ice for over a year.

If they had made the journey in 2023, they would have sailed through open water – where sea ice should be, write experts from University of Tasmania. theconversation.com/the-limits-of-…

Antarctica's floating ice shelves aren't immune to El Nino heat.

As Maurice Huguenin + colleagues (@UNSW, University of Tasmania) write, El Niño can direct more warm water to the base of West Antarctic ice shelves, accelerating melting and increasing global sea level. theconversation.com/heat-from-el-n…

More evidence of surface mass balance increase (~snowfall) in East Antarctica in the last two centuries. Linked to air temperature increase.

Doesn't offset losses from West Antarctica

Two major reviews led by AAPP researchers about the future of Southern Ocean ecosystems in a changing world have been published in high-impact journal Nature Reviews Earth & Environment 🌈 this year (a short 🧵)

🚨New Review!

The Southern Ocean represents a substantial carbon sink.

Boyd et al. describe how expanding observations are providing increasing insight into the contribution of biota to the carbon cycle in the Southern Ocean
