A robotic float, 'Argo', reveals the present state of affairs of the Denman and Shackleton ice shelves in East Antarctica.

The Antarctic, or Southern, Ocean is the world’s least-explored and least understood. But a team of scientists in land-locked Boulder has recently made a discovery that may lead to a better ...

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 ...

Scientists have uncovered a new threat hiding under the floating edges of Antarctica: fast moving, stormlike swirls of water that attack the ice from below. These secretive currents, spinning in the ...

Intense storms that sweep over the Southern Ocean enable the ocean to absorb more heat from the atmosphere. New research from ...

A drone that went on an unexpected journey through Antarctic ice sheets has been saved by scientists, bringing with it never ...

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

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

Deep ocean water in the Antarctic is heating up and shrinking, with potentially far-reaching consequences for climate change and deep ocean ecosystems, according to a report. “Antarctic bottom water” ...

Our ocean float spent years adrift in the Antarctic ocean and beneath massive ice shelves. What it found will help us ...

In a new study soon to be published in Geophysical Research Letters, I present evidence for hundreds of these quakes in ...
