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.
The Antarctic Circumpolar Current keeps Antarctica cold.
The Antarctic Circumpolar Current provides a barrier to heat that keeps warm subtropical waters away from Antarctica. Yet, there are a few places where the heat gets through.
Few work environments offer greater isolation than Antarctica.
Isolation at work can be unhealthy. But it can also be a good thing – as this researcher found out when he walked solo from Melbourne to Sydney.
Brazil, home to the Amazon, is one of just five ‘mega-wilderness’ countries.
More than two-thirds of Earth's remaining wilderness is in the hands of just five countries, according to a new global map. A concerted conservation effort is needed to save our last wild places.
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.

Geometric icebergs can form around Antarctica, although such a perfect rectangle is unusual.

Sidney Jeffryes achieved a world first by establishing wireless contact between Antarctica and Australia. But his mental illness meant he gradually vanished from history - until now.
Lush moss beds in East Antarctica’s Windmill Islands.
Mosses are the only plants that can withstand life in East Antarctica's frozen landscape. But a new study shows that life is getting even harder, as ozone loss and climate change make conditions even drier.
Most people will never visit Antarctica but music can evoke the continent in myriad ways.

Scientific research into the effects of climate change in Antarctica - and its history of intrepid exploration - is inspiring contemporary Australian composers.
In contrast to common perceptions, Antarctic seafloor communities are highly diverse. This image shows a deep East Antarctic reef with plenty of corals, sponges and brittlestars. Can you spot the octopus?

Life on the Antarctic seafloor is surprisingly diverse – and half of the species live nowhere else on Earth. Now scientists can accurately map this unique biodiversity.

For just ten years Antarctica was home to a nuclear power station called "Nukey Poo".
Southern bull kelp can drift huge distances before washing ashore.
A chance discovery of some kelp that floated for 20,000km before washing up on an Antarctic beach has opened up a new chapter in our understanding of the currents that swirl around the Southern Ocean.
Preliminary results of a study have shown microplastics have reached in a newly revealed Antarctic environment.
Under the terms of the current treaty all commercial mining is forbidden, but rumblings of discontent are stirring beneath the ice.
As the West Antarctic Ice Sheet melts, the land beneath rebounds – at a faster rate than thought.
Scientists have found that the bedrock underneath the West Antarctica Ice Sheet has the potential to rebound in response to melting faster than thought, which could act to stabilize the ice.
As the world prevaricates over climate action, Antarctica’s future is shrouded in uncertainty.

What will Antarctica look like in 2070? Will the icy wilderness we know today survive, or will it succumb to climate change and human pressure? Our choices over the coming decade will seal its fate.
Without floating sea ice, climate-weakened ice shelves are wide open to attack by waves.

Since 1995, several ice shelves off the Antarctic Peninsula have abruptly disintegrated. A new analysis suggests that these events are triggered when ice shelves lose their buffer of floating ice.

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.

We used 11 different satellite missions to track Antarctica’s contribution to rising sea levels.
The Homeward Bound initiative works with women in science to enhance their opportunity to take up leadership roles globally.
This year 77 women took part in the largest all-female expedition to Antarctica as part of a leadership training program. Rough weather enroute put group decision-making skills to the test.
