Antarctic sea ice is more than just a platform for penguins. The sea ice's high reflectivity influences the whole Earth's ...

New research reveals Antarctic sea ice has hit record lows three times since 2017, creating cascading effects on global ...

The ocean around Antarctica is rapidly getting saltier at the same time as sea ice is retreating at a record pace. Since 2015 ...

On her first dedicated scientific voyage to Antarctica in March, the Australian icebreaker RSV Nuyina found the area sea-ice ...

Along with seals, seabirds and baleen whales, penguins gorge mainly on Antarctic krill, a shrimp-like crustacean that thrives on the kind of phytoplankton found under sea ice. Unlike the Arctic ...

At the same time, declining sea ice is exacerbating challenges for Antarctic krill from the earliest stages of life. Krill larvae don’t have the lipid reserves of adult krill to get through the ...

Antarctica has lost sea ice equivalent in area to Greenland – and it has not returned, according to new satellite data. This ...

Scientists at the Australian Antarctic Partnership Program are just beginning to understand the dire effects of extremely low ...

Phytoplankton, primary productivity, Antarctic krill, whales and seabirds were concentrated where winter sea-ice extent is maximal, whereas salps were located where the sea-ice extent is minimal.

Extreme lows in sea ice induce many changes in the physical, ecological, and societal systems of Antarctica and the Southern Ocean. A: an average sea ice summer. B: an extreme low sea ice summer. In B ...

The maximum Antarctic sea ice extent in 2023, shown here, was the lowest on record. The yellow line shows the average winter maximum of satellite observations from 1981 to 2010.

Instead, larvae stick to the sea ice, feeding on ice algae until the sun—and the phytoplankton—returns in spring. “Sea ice is critically important for Antarctic krill,” Flores says.
