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

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 ...

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

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

Antarctic sea ice extent has fallen dramatically in recent years – the effects include accelerated ocean warming, faster loss of inland ice sheets and severe impacts on wildlife ...

In recent years, the Southern Ocean has undergone one of the most dramatic environmental shifts observed anywhere on Earth.

Populations of Antarctic seals have halved over 50 years amid a warming climate and shrinking sea ice, a new study has shown.

More NASA satellites looked down on huge cracks forming in sea ice in Canada's far north. What is it? The Amundsen Gulf is named after Roald Amundsen, a Norwegian explorer who, in the early 1900s ...
