Southern Ocean Saltier, Hotter and Losing Ice Fast as Decades-Long Trend Unexpectedly Reverses
- On 30 June, NASA detected unusual ocean signals indicating rising surface salinity and record-low sea ice in the Southern Ocean, findings published in PNAS.
- Supported by British Antarctic Survey data, robotic gliders detected a freshwater layer up to nine meters, indicating meltwater disrupting stratification near mega-iceberg A-68A.
- Satellite records show 2.5 million sq km of sea ice lost and surface salinity rising south of 50° latitude, with Silvano warning of a dangerous feedback loop.
- Recent satellite data shows increased salt levels and record low sea ice, leading to faster warming, storm intensity, and habitat loss in Antarctica.
- The unexpected rise in Southern Ocean surface salinity and record low sea ice highlight gaps in climate models, emphasizing the need for ongoing research on long-term carbon impacts.

New study reveals how Antarctica's focuss are responding to changes in Antarctica's marine ice and what long-term changes can mean for its future survival
The Southern Polar Sea has enormous influence on the global climate. An unexpected development there makes researchers puzzle.
Antarctica’s ocean flip: Satellites catch sudden salt surge melting ice from below
A massive and surprising change is unfolding around Antarctica. Scientists have discovered that the Southern Ocean is getting saltier, and sea ice is melting at record speed, enough to match the size of Greenland. This change has reversed a decades-long trend and is letting hidden heat rise to the surface, melting the ice from below. One of the most dramatic signs is the return of a giant hole in the ice that hadn’t been seen in 50 years. The co…
Antarctica's shrinking sea ice threatens wildlife, climate stability
Antarctic summer sea ice is retreating at record speeds, unleashing a chain reaction of environmental and social consequences that Australian experts say could profoundly alter the global climate and ecosystems, new research has revealed.Record lows
