Microphones on the seafloor recorded life under the Antarctic ice for two years – inadvertently catching seal trills and chirps that are above the range of human hearing. Could they be for navigation?
Carbon emissions are chilling the atmosphere 90km above Antarctica, at the edge of space
It would be the first concrete runway in Antarctica and have the biggest footprint of any project in the continent's history.
As the world warmed from the last ice age, a rise in carbon dioxide levels stalled for nearly 2,000 years. That's always puzzled scientists, but now they think they know what happened.

Two centuries after it was first sighted by Russian explorers, Antarctica is a key site for studying the future of Earth's climate – and for global scientific cooperation.
One of two underwater gliders is deployed from a research ship into Antarctic waters.
Sending autonomous vehicles to the Southern Ocean can be fraught with anxiety, especially if one of them doesn't make radio contact when it's supposed to.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical 'cores' of the sediment and rock that's as much as two miles down at the ocean floor.
Sea ice responds to changes in winds and ocean currents, sometimes with origins thousands of kilometres away.
Antarctic sea ice cover fell to an all-time low recently and hasn't yet recovered. Why? The initial answers could lie in an unlikely place – the tropics.
In Antarctica, many countries want a piece of the action.
There are some limits on what countries can do in the Antarctic, but not when it comes to science.

Scientific research into the effects of climate change in Antarctica - and its history of intrepid exploration - is inspiring contemporary Australian composers.
Preliminary results of a study have shown microplastics have reached in a newly revealed Antarctic environment.

Last summer one of Antarctica's floating ice shelves calved an iceberg the size of Delaware – but scientists say other less dramatic changes reveal more about how and why Antarctica is changing.
The ever changing Antarctic landscape.
Australia must keep up its scientific presence in Antarctica and work with others if it's to maintain its territorial claim on the frozen continent.
