Antarctica's remote and mysterious current has a profound influence on the climate, food systems and Antarctic ecosystems. Can we stop it weakening by 2050?

With Antarctica's climate warming at an unprecedented rate, scientists are battling with dangerously thin ice and equipment falling through into the sea.

Icebergs produce some of the loudest natural noises in the oceans. Can we learn anything about their birth, life and death by listening in?

When scientists peered beneath one of Antarctica's floating ice shelves, they were surprised to find an upside-down landscape of peaks, valleys and plateaus.

The world's largest icebergs break off the Antarctic ice sheet. As they drift and melt in the Southern Ocean, they create a unique environment around them.

In the coldest place on Earth, workers wage an epic battle with the extreme landscape – aided by specially trained penguin-movers.

Isolated for six months one winter, a group of scientists changed how they spoke.

It comes from outer space. Mary Westover talks to the scientists searching for hidden micrometeorites in Antarctica and on cathedral roofs.
