Alaskan Arctic fish minimally contaminated with “forever chemicals”
Fish in the Beaufort and Chukchi Seas appear to have little exposure to mercury and PFAS, the so-called “forever chemicals”
A beetle introduced in Kerguelen, perpetually voracious
A beetle introduced to Kerguelen, Merizodus soledadinus, is so active that it is thought to be capable of eradicating the archipelago’s native flies. Scientists at the French Polar Institute have discovered that its predatory activity does not diminish as its population grows and its prey diminishes.
Whale populations before whaling much smaller than thought
Before commercial whaling began, the number of humpback whales in the North Atlantic was apparently 86 per cent lower than previously thought.
Do sled dogs turn Svalbard greener?
A study aims to show that increased nutrient inputs from dog waste results in the surrounding tundra turning greener and therefore more productive.
Increased risk of avian influenza H5 in the Falklands
The arrival of spring in the southern hemisphere is raising concerns about the resurgence of the H5N1 virus and the risk of it entering the Antarctic.
Microplastics in penguin chicks’ bellies
Less than four weeks old, Gentoo penguin chicks already carry an enormous amount of microplastics in their digestive tracts, especially polyethylene.
A Swiss team in the footsteps of two botanists from the past
Based on scientific data established in Greenland by two botanists 90 and 20 years ago, a Swiss research team followed the same routes to document plant species and the impact of global warming on flora.
Breeding failure in emperor penguins last winter – and this year?
According to a study, 4 out of 5 emperor penguin colonies in the Bellinghausen Sea lost all their chicks last southern spring due to poor ice conditions. This does not bode well for this year with its record low sea ice.
Paw prints allow soft identification of polar bears
As polar bears walk across snow and ice, they leave tiny skin particles in their paw prints, which a University of Idaho research team used to identify individual bears based on genetic analysis.
Narwhals and belugas remain under pressure in East Greenland
The population of narwhals in East Greenland is far from stable, according to scientists, yet the Greenlandic government aims to maintain the annual hunting quota of 50 animals for 2024.
Polyester fibers find their way into Arctic marine mammal tissues
Microplastics ingested by whales, dolphins and seals do not necessarily remain in their digestive tract or are excreted but can enter the fatty tissue of various body parts or even the lungs.
When Antarctic stations cause pollution
A study conducted near an Australian station reveals significant marine pollution linked to poor waste management.
Tiny teeth point to rare paleo Arctic mammal
A team of paleontologists has excavated the tooth of an extinct mammal, a contemporary of the Arctic dinosaurs, from a Cretaceous coniferous forest.
Young scientists explore Kalaallit Nunaat aboard Que Sera
The Fondation Pacifique takes young scientists on board to explore the Northwest Passage, starting in the North Atlantic between Newfoundland and Greenland, then along the west coast of Kalaallit Nunaat.
Extreme events in Antarctica go up, are environmental protocols still enough?
A study indicates that extreme events in Antarctica will increase, not least due to climate change, and it calls existing environmental protection protocols into question.
Bowhead whales possibly outperform elephants
An extensive study shows that the gestation period of Bowhead whales may last 23 months. So far, a 14-month pregnancy has been assumed.
More protection from enemies despite neighbor dispute in king penguins
Since more eyes detect aggressors earlier, king penguins are better protected in very dense groups, despite more hostilities with neighbors.
Underwater sounds from the Disko Bay via livestream
Soon, the entire world will be able to listen live to the unique Arctic underwater sounds in Greenland’s Disko Bay: Starting next spring, an acoustic monitoring station near Qeqertarsuaq will record the sounds of marine mammals.
When Greenland had melted
Vegetation traces found in an ice core taken nearly 60 years ago in the far north-west corner of Greenland suggest that the ice sheet had largely melted over 400,000 years ago.
Medical use for Antarctic seaweed?
Antarctic algae may have a stronger health-promoting effect than their relatives from warmer latitudes.
A sea lily snatches a ride on a crab in the Svalbard fjords
From the deck of their magnificent sailing boat, in a breathtaking natural scenery, researchers are studying an opportunistic sea lily that hitchhikes on the back of a crab.
1,300 dead penguins on Uruguay’s coastline
Dozens of dead Magellanic penguins have been found daily on Uruguay’s beaches since the beginning of this month. It is estimated that a total of up to 2,000 animals could wash up.
Don’t mess with menopaused orca moms
