Antarctic ice shelf 'sings' as winds whip across its surface
Winds blowing across snow dunes on Antarctica's Ross Ice Shelf cause the massive ice slab's surface to vibrate, producing a near-constant set of seismic 'tones' scientists could potentially use to monitor changes in the ice shelf from afar, according to new research.

UK government backs creation of Antarctic wildlife reserve
The UK government has thrown its weight behind the creation of the world’s biggest environmental sanctuary, covering a huge swathe of the Antarctic ocean. The massive 1.8m sq km reserve – five times the size of Germany – would ban all fishing in a vast area of the Weddell Sea and parts of the Antarctic peninsula, safeguarding species including penguins, killer whales, leopard seals and blue whales.

Bizarre Particles Keep Flying Out of Antarctica's Ice, and They Might Shatter Modern Physics
There's something out there that physicists have never seen before, and it's coming up from the bottom of the Earth. Scientists think it's a brand-new particle.

New study puts a figure on sea-level rise following Antarctic ice shelves’ collapse
An international team of scientists has shown how much sea level would rise if Larsen C and George VI, two Antarctic ice shelves at risk of collapse, were to break up. While Larsen C has received much attention due to the break-away of a trillion-tonne iceberg from it last summer, its collapse would contribute only a few millimetres to sea-level rise. The break-up of the smaller George VI Ice Shelf would have a much larger impact. The research is published today in the European Geosciences Union journal The Cryosphere.

Krill fishing firms back Antarctic ocean sanctuary
The creation of the world’s biggest ocean sanctuary, protecting a huge tract of remote seas around Antarctica, has come a step closer after major fishing companies came out in favour of the plan. A global campaign – spearheaded by Greenpeace and backed by 1.7 million people – had put massive pressure on the krill fishing industry and retailers amid fears it was endangering one of the world’s last great wildernesses, undermining the global fight against climate change.

Antarctica is melting faster than anyone thought, and we're not ready for the sea level rise that's coming
The melting rate of Antarctic ice has tripled in recent years. If the acceleration of ice melt were to continue, it could potentially cascade.

Captain Scott's polar samples re-examined 100 years on
They look like shrivelled pieces of leather – in fact they are dried communities of microbes scooped up by Captain Robert Falcon Scott’s team of polar explorers. And they could help scientists keep tabs on how Antarctica is changing. While perhaps most famous for the ill-fated Terra Nova expedition from 1910-13, Scott also led the 1901-4 Discovery Expedition to Antarctica that was proclaimed a success, largely due to the pioneering scientific studies carried out on the trip. Among the research carried out during this earlier mission...

Scientists harvest 1st vegetables in Antarctic greenhouse
Scientists in Antarctica have harvested their first crop of vegetables grown without earth, daylight or pesticides as part of a project designed to help astronauts cultivate fresh food on other planets. Researchers at Germany’s Neumayer Station III say they’ve picked 3.6 kilograms (8 pounds) of salad greens, 18 cucumbers and 70 radishes grown inside a high-tech greenhouse as temperatures outside dropped below -20 degrees Celsius (-4 Fahrenheit).

Overfishing of Krill Is Disrupting Antarctic Food Chains
Krill oil, rich in heart-healthy omega-3 fatty acids, is a popular nutritional supplement around the world. However, according to a recent report from Greenpeace, growing demand is fueling commercial fishing in Antarctica's icy waters that could make it harder for all kinds of polar marine life to survive climate change threats.

Arctic has warmest winter on record: 'Never seen anything like this'
The Arctic winter has ended with more news that is worrying even the scientists who watch the effects of climate change closely. The region experienced its warmest winter on record. Sea ice hit record lows for the time of year, new US weather data revealed on Tuesday. “It’s just crazy, crazy stuff,” said Mark Serreze, director of the National Snow and Ice Data Center in Boulder, Colorado, who has been studying the Arctic since 1982. “These heat waves – I’ve never seen anything like this.”

UK team set for giant iceberg expedition
Scientists will set out in the next week to study an Antarctic realm that has been hidden for thousands of years. A British Antarctic Survey-led team will explore the seabed ecosystem exposed when a giant iceberg broke away from the Antarctic Peninsula in 2017. The organisation has also released the first video of the berg, which covers almost 6,000 sq km.
