Washington - 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.

Antarctic's giant sea spiders show resilience to warming waters

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.

Melting ice sheets may cause 'climate chaos': study

Paris - 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.

Huge cavity in bottom of Antarctic glacier signals rapid decay

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.”

Remains of ancient life found beneath Antarctic ice

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

Paris - 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.

Win for wildlife as krill fishing restricted in Antarctica

Sydney - 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.

Antarctic researchers mark winter solstice with icy plunge

Sydney - Scientists based in Antarctica welcomed the winter solstice by plunging into icy waters Thursday as part of a "mad tradition" heralding the return of brighter days after weeks of darkness.In temperatures of -22 degrees Celsius (-7.

Antarctica is shedding ice at an accelerating rate

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.

Sea level fears as more of giant Antarctic glacier floating than thought

Sydney - 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.

Antarctic sea ice shrinks for second-straight year

Sydney - 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.

Antarctica: a laboratory for climate change

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.

Scientists set off to explore new Antarctic ecosystem

London - 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.

Robots en route to Antarctica to study underside of ice shelves

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.

Evidence points to collapse of Pine Island and Thwaites glaciers

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.

260-million-year-old fossil forest discovered in Antarctica

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.

New ice crack forces Halley VI Research Station to close again

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.

Hopes dashed for giant new Antarctic marine sanctuary

Sydney - Hopes for a vast new marine sanctuary in pristine East Antarctica were dashed Saturday after a key conservation summit failed to reach agreement, with advocates urging "greater vision and ambition".

Drive for giant new marine sanctuary in Antarctica

Sydney - Australia and France kick off a fresh push Monday to create a vast marine sanctuary in pristine East Antarctica, hoping to build on the success of landmark deal secured last year at a key annual conservation summit.

Paris - A Delaware-sized iceberg, one of the largest ever seen, was set adrift after snapping from a West Antarctic ice shelf that will be closely watched for signs of collapse, scientists said Wednesday.

Trillion-tonne iceberg breaks off Antarctica: scientists

Paris - A trillion-tonne iceberg, one of the biggest on record, has snapped off the West Antarctic ice shelf, said scientists Wednesday who have monitored the growing crack for months.

Multiple icebergs ready to break off Larsen C Ice Shelf

As of Friday, July 7, the Larsen C Ice Shelf is showing very clear signs is it about to calve, according to the latest report from Project Midas scientists. Just three miles stand between the fast-growing crack and the open water.

Sydney - Antarctic researchers welcomed the winter solstice with an exhilarating plunge into icy waters Wednesday as they look forward to brighter days after weeks of darkness.

House flies invade warmer Antarctica threatening native species

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.
