The dramatic loss of sea ice around Antarctica has occurred with the re-emergence of the Maud Rise polynya in the Weddell Sea ...

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

Antarctic sea ice extent has fallen dramatically in recent years – the effects include accelerated ocean warming, faster loss ...

Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ...

A sudden salinity spike in the Southern Ocean is accelerating Antarctic ice loss and triggering a dangerous climate feedback ...

New research reveals the importance of winter sea ice in the year-to-year variability of the amount of atmospheric CO2 absorbed by a region of the Southern Ocean.

Emperor penguin populations are falling much faster than expected. Ice is melting beneath their chicks before they’re ready.

A breakthrough study has uncovered that the Southern Ocean's power to pull carbon dioxide from the atmosphere fluctuates dramatically depending on winter sea ice. When sea ice lingers longer into ...

New research reveals the importance of winter sea ice in the year-to-year variability of the amount of atmospheric CO2 absorbed by a region of the Southern Ocean. In years when sea ice lasts ...

Much of the Southern Ocean surrounding the west Antarctic Peninsula is covered by sea ice in winter, which disappears in spring and summer. In spring and summer, phytoplankton growth and melt ...

Bowhead whales are endemic to the icy waters of the Arctic and prefer living in shallow waters near sea ice, filtering krill and tiny crustaceans called copepods for food. However, the Arctic is ...

There’s another challenge. Iceberg calving, where chunks of land ice break off and fall into the ocean, is a natural phenomenon, but it appears to be happening more regularly as the climate warms.
