Slowing deep Southern Ocean current may be linked to natural climate cycle – but that’s no reason to stop worrying about melting Antarctic ice

Freshening seawater around Antarctica is disrupting a global ocean conveyor which regulates the climate.

Glaciers have existed on Earth for at least 60 million years – far longer than previously thought

Scientists used satellites to map tens of thousands of glacial landforms in Antarctica’s highest mountains.

Scientists in Antarctica discover a vast, salty groundwater system under the ice sheet – with implications for sea level rise

Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.

Mapping out meteorites in Antarctica: scientists’ bid to uncover our solar system’s deep past

Scientists have crafted the world’s first “treasure map” to reveal Antarctica’s meteorites. These chunks of stone-like material could throw light on the mysteries of our early solar system.

Exploring Antarctica’s hidden under-ice rivers and their role in future sea-level rise

Researchers have surveyed an Antarctic under-ice river for the first time directly, and their observations support the idea that such sub-glacial rivers form estuaries as they flow into the ocean.
