Study pinpoints cold adaptations in nervous system of Antarctic octopus
Laden with dissolved salt, Antarctic waters can hover just above freezing and even dip below it. Temperatures this low would likely kill the animals that prosper in warmer waters further north. Yet, some creatures have found ways to live in this inho.....»»

As Antarctic sea ice continues its dramatic decline, we need more measurements and much better models
After two seasons of record-breaking lows, Antarctica's sea ice remains in dramatic decline, tracking well below any winter maximum levels observed since satellite monitoring began during the late 1970s......»»
Antarctic sea ice hits lowest winter maximum on record: US data
The sea ice around Antarctica likely had a record low surface area when it was at its maximum size this winter, a preliminary US analysis of satellite data showed Monday......»»
Study finds Antarctica"s glacial border migrates for miles with the tide
The grounding line of the southern Ronne Ice Shelf in Antarctica can shift up to 15 km with changing tides, new analysis shows. The research, published today in The Cryosphere, examines the key region where land-based Antarctic ice spills over into t.....»»

Polar experiments reveal seasonal cycle in Antarctic sea ice algae
In the frigid waters surrounding Antarctica, an unusual seasonal cycle occurs. During winter, from March to October, the sun barely rises. As seawater freezes it rejects salts, creating pockets of extra-salty brine where microbes live in winter. In s.....»»
Devastatingly low Antarctic sea ice may be the "new abnormal," study warns
For most of us, Antarctic sea ice is an abstraction—something far away we may have seen on a documentary. But the radiant white sheets of ice floating on the seas around the snowy continent are a crucial component of Earth's climate processes......»»

Researchers find Antarctic ice shelves thinner than previously thought
As global ice dams begin to weaken due to warming temperatures, a new study suggests that prior attempts to evaluate the mass of the huge floating ice shelves that line the Antarctic ice sheet may have overestimated their thickness......»»
Dramatic images show why emperor penguins were hit with catastrophe
At the bottom of the world, emperor penguins have experienced tragedy.Scientists at the British Antarctic Survey report an "unprecedented breeding failure" in some big, well-observed colonies where sea ice had largely or completely vanished in 2022......»»
Tides may be responsible for up to 69% of under-ice melting in an Antarctica ice shelf
The ice shelves—the marine-terminating glaciers of the Antarctic Ice Sheet—are melting, and it's not just because of rising atmospheric temperatures. In a one-two punch, ice shelves in Antarctica are fighting a losing battle against rising temper.....»»
Antarctica has never needed our help more, says researcher who has spent 40 years studying the frozen continent
After decades immersed in Antarctic science, I've learned that physical and biological changes rarely occur smoothly. More often than not, they unfold in sharp steps. Right now, Antarctica's climate and ecosystems are experiencing disturbing changes......»»
