For more than half a century, biologists studying Antarctica focused their research on understanding how organisms cope with the continent's severe drought and the coldest conditions on the planet.

Scientists have wondered for decades why marine animals that live in the polar oceans and the deep sea can reach giant sizes there, but nowhere else. Researchers from the Universities of Hawaii and Montana decided to find out.

Billions of tonnes of meltwater flowing into the world's oceans from the Greenland and Antarctic ice sheets could boost extreme weather and destabilise regional climate within a matter of decades, researchers said Wednesday.

A massive cavity that is two-thirds the size of Manhattan and nearly the height of the Chrysler Building is growing at the bottom of Thwaites Glacier in West Antarctica - a discovery that NASA scientists called “disturbing.”

Scientists in Antarctica have found preserved carcasses of tiny animals in Subglacial Lake Mercer, buried under more than 3,500 feet of ice.

A plan to create the world's largest marine sanctuary in Antarctic waters was shot down when a key conservation summit failed to reach a consensus, with environmentalists on Saturday decrying a lack of scientific foresight.

Moderate global temperature rises of just two degrees Celsius could still be enough to melt parts of the largest ice sheet on Earth and raise sea levels by several metres, experts warned on Wednesday.

Five major krill fishing firms Tuesday agreed to halt operations across huge swathes of the Antarctic to help protect wildlife in a move hailed as "bold and progressive" by conservationists.

The melting of Antarctica is accelerating at an alarming rate, with about 3 trillion tons of ice disappearing since 1992, an international team of ice experts said in a new study.

More of a giant France-sized glacier in Antarctica is floating on the ocean than previously thought, scientists said Tuesday, raising fears it could melt faster as the climate warms and have a dramatic impact on rising sea-levels.

Sea ice cover in Antarctica has dropped to its second-lowest on record, Australian authorities said Friday, adding that it was not yet clear what was driving the reduction after several years of record-highs.

A decade ago, a thick layer of ice covered the Collins Glacier on Antarctica's King George Island.Now, the rocky landscape is visible to the naked eye, in a region that is both a victim of and a laboratory for climate change.

A team of international scientists led by the British Antarctic Survey set off on Wednesday to explore a mysterious marine ecosystem that has lain hidden under an ice shelf for up to 120,000 years.

It has become increasingly common to see cliff-sized chunks of glacial ice falling into the Southern Ocean, suggestive of a warming climate. But scientists don't know what's going on beneath Antarctica's ice sheets., so they are preparing to find out.

In a remote region of Antarctica known as Pine Island Bay, the Thwaites and Pine Island glaciers sprawl across a plain over 150-miles-long, widening as they go inland to a reserve of ice two-miles-thick, about the size of Texas. They are melting fast.

Long ago, Antarctica was covered in forests. The ancient trees were able to withstand prolonged periods of pure sunlight or complete darkness, transitioning rapidly between the seasons. But they were victims of the world's greatest mass extinction event.

The "Halloween" crack that popped up last year around the end of October is not about to give the British Antarctic Survey (BAS) a break. BAS has been forced to abandon its Halley VI research station for a second winter due to a new crack.

Scientists say that increasing number of houseflies that arrive in Antarctica on ships are surviving as the continent warms up. Their growing population can introduce deadly pathogens that could have a harmful effect on indigenous lifeforms.

Large-scale melting of snow and ice on Antarctica's massive Ross Ice Shelf, brought on by an unusually warm stretch of weather in the austral summer of 2015-2016, has been documented for the very first time, according to a new study.

ESA's CryoSat mission provides data to determine the precise rate of change in the thickness of the polar ice sheets and floating sea ice. It is capable of detecting changes as little as 1 cm per year. The information from CryoSat is leading to a better understanding of how the volume of ice on Earth is changing and, in turn, a better appreciation of how ice and climate are linked. ESA

Among the most striking of images found is that of Alexander Stevens, who served as the Shackelton Expedition's chief scientist. Here he is pictured on board the SY Aurora some time between 1914 and 1917.

Thwaites Glacier's outer edge. As the glacier flows into the ocean, it becomes sea ice and drives up sea level. Thwaites Glacier ice is flowing particularly fast, and some researchers believe it may have already tipped into instability or be near that point, though this has not yet been established.
