The Polar Retrospective – Return to sender from the Arctic
While soot and pollutants are transported from the south to the Arctic, substances bound in the permafrost are now being transported back to the south by the tundra fires.
Monitoring Antarctic biodiversity with high-tech towers
The Australian Antarctic Program is preparing an observation tower equipped with environmental sensors, which will be part of the Antarctic Near-Shore and Terrestrial Observation System (ANTOS).
Ancient poppy seeds and willow wood offer clues to the Greenland ice sheet’s last meltdown and a glimpse into a warmer future
Close inspections of the soil beneath the Greenland Ice Sheet show that less than one million years ago it was almost entirely gone.
When a strait hides a piece of continent
A team of researchers has just revealed the existence of a microcontinent located on the Davis Strait and formed 60 million years ago during plate movements.
Spiders have been around Antarctica for 9 million years
Take a look under the rocks of the sub-Antarctic islands and you’ll probably see a spider crawling out. A study shows that they were not introduced by explorers.
Leopard seals’ sex life (almost) revealed
Thanks to the observation of a courtship ritual, we now know more about the sexual behaviour of the mysterious leopard seal. A mating process based on vocalizations that takes place far from the Antarctic ice.
Joey, the fakest bear in the world
The fictional story of an albino brown bear relocated to the North Pole has resurfaced, causing a stir on social networks. Not without consequences for the discourse of experts and the public’s opinion of the work of wildlife conservation specialists.
We used 1,000 historical photos to reconstruct Antarctic glaciers before a dramatic collapse
Two Australian scientists delved deep into a valuable archive of more than 300,000 historical photographs from Antarctica to understand how glaciers reacted in the past.
Fossil forest in Canada’s Arctic: Three new extinct walnut species discovered
Less than 1,000 kilometers from the North Pole, 45 million years ago there was a species-rich forest whose remains were discovered almost 40 years ago. But only now has a research team discovered that three previously unknown walnut species were also growing there.
Volcano near Grindavík likely to keep Iceland busy for a long time to come
It is difficult to predict how long the volcanic activity on the Reykjanes peninsula in Iceland will last, but it is likely to keep the people on the island busy for a long time to come.
How a Greenland mine is becoming vital to NASA’s moonbase plans
To build anything on the Moon, a mineral found in Greenland is needed, so NASA, ESA, and universities across the world are buying more and more of it.
Close encounters of the 3rd kind under Antarctica’s old blue ice
Near mountain ranges, multi-millennia-old ice resurgences are home to active ecosystems never before recorded.
Twice as much meltwater: slush on Antarctic ice shelves was underestimated
On the ice shelf, meltwater in the form of slush occurs more frequently than liquid meltwater accumulations in the Antarctic peak summer, but has not yet been sufficiently taken into account in climate models.
From Australian pink sand beaches to undiscovered Antarctic mountain belt
A team of Australian scientists has established a link between the pink beaches of southern Australia and the Great White Continent, and in the process has discovered a previously undiscovered Antarctic mountain belt.
ArcNet: A network tackling biodiversity loss in the Arctic
This spring, ArcNet became available as a framework that takes a holistic view of Arctic Ocean protection and involves all Arctic stakeholders in the designation of protected areas.
Oldest Southern Hemisphere fossil of a polar marine reptile found
A nothosaur vertebra found on the South Island of New Zealand has now been identified as the oldest fossil of a polar marine reptile ever found in the Southern Hemisphere.
Why are there suddenly salmon in Canada’s far north-west?
Northwest Territories residents and scientists work together to understand how new species of fish end up in the nets of subsistence fishermen. They find that salmon pass through the open waters of the Bering, Chukchi and Beaufort Seas.
‘Toasty’, ‘Country mice’, ‘Greenout’ – study reveals “Antarctic language”
When staying at English-speaking Antarctic stations, you can and should expand your vocabulary by a few terms if you want to be part of the community.
Of ice and fire: what sea salt in Antarctic snowfall reveals about bushfires worse than the Black Summer
Australia has a long history of bushfires. The 2019-2020 Black Summer was the worst in recorded history. But was that the worst it could get?
Antarctic ice shelves can break under the weight of meltwater lakes
Recent time-lapse images and GPS data from the George VI Ice Shelf show that the numerous meltwater lakes on the Larsen B Ice Shelf may have been one of the causes of its sudden disintegration in 2002.
The universal flapping of wings
Like Leonardo da Vinci in his day, Danish physicists at Roskilde University are interested in animal proportions.
2-in-1 update of the interactive Antarctic map: Updated data & new look
Along with the regular update of the Antarctic Digital Database, the British Antarctic Survey recently published a new interactive map viewer.
Permafrost could release more greenhouse gases than previously assumed
Microbes that are currently still trapped in the permafrost can apparently also break down polyphenols. The amount of greenhouse gases escaping from thawing permafrost is therefore higher than expected.
