New findings about ocean processes in the Antarctic show melting ice shelves and changes to sea ice could have catastrophic implications for the global climate.

A new study highlights the key role the Southern Ocean plays in the Earth’s climate system. Around 12,000 years ago, the last ...

If it were to melt completely, the vast West Antarctic Ice Sheet (WAIS) holds enough ice to raise the global sea levels by 4 ...

While Antarctic meltwater drives rising sea levels, models show it also delays greenhouse gas-induced warming. That’s because ...

As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea ...

As the oceans warm, their capacity to melt ice shelves and glaciers increases. Scientists rely on a network of oceanic ...

A robotic float has measured the temperature and salinity from parts of the ocean never sampled before—underneath massive ...

And so, the Argo float’s trip under the ice turned out to be an incredibly lucky accident. During an eight-month period, the ...

Antarctica is warming roughly twice as fast as the rest of the planet, putting its vast ice sheets, surrounding oceans, and ...

Beneath the ice of Antarctica, scientists discover a “fish city” with protected nests more than 950 feet deep.
