Satellite imagery has revealed a yet-to-be-explained rise in the Southern Ocean's salinity. It could be a key factor in the decline of the region's sea ice.

New research from the Chilean Patagonia has identified a link between glacial retreat and underground volcanic activity ...

In a nutshell • The Antarctic Circumpolar Current, Earth’s strongest ocean current, is projected to weaken by about 20% by 2050 due to freshwater from melting Antarctic ice sheets. • Unlike ...

A salty surge in the Southern Ocean is melting Antarctic sea ice from below — and causing dramatic changes scientists didn’t ...

This discovery, driven by data from the European Space Agency's SMOS (Soil Moisture and Ocean Salinity) satellite, challenges ...

Scientists know the ice covering Antarctica is melting, but they don’t fully understand all the forces at play. Now, they’ve made a surprising discovery that might help explain ice loss across ...

The outlook for "Doomsday Glacier" just got gloomier. Scientists are warning the Antarctic Ice Sheet, known formally as the Thwaites Glacier, will deteriorate "further and faster" and that sea ...

A new model illustrates how meltwater from the Antarctic ice can trap heat under ice shelves, increasing melting in a feedback loop.

Scientists have been struggling to understand why Antarctic sea ice has declined rapidly and continues to decline. Read more ...

Studies on Antarctica have documented how temperatures, glaciers, oceans and wildlife are reacting to the warming consequences of fossil fuel emissions. A place this remote and isolated makes a ...

Scientists analyzed the chemical fingerprint of the ocean and microbes retrieved from sediments and water at the bottom of a subglacial lake called Mercer Lake to describe where the feisty microbes ...
