‘Sparta’ – the best preserved ice age animal
Following the sensational discovery of two mummified cave lion cubs in the permafrost of Yakutia in 2017 and 2018, there are now further findings after more detailed analyses.
Plastic pollution affects the development of Antarctic krill
Plastic pollution in combination with ocean acidification hinders the development of Antarctic krill in the Southern Ocean. This is shown by a recently published study.
Extreme climatic events increasingly threaten emperors
Emperor penguins are under increasing pressure and could be virtually extinct by 2100 due to clustered extreme events.
“Atlantification” causes ice caps in Russian Arctic to melt faster
Warming is rapidly advancing in the Russian Arctic as well. The melting of glaciers and ice caps on high Arctic archipelagos is driven primarily by warm Atlantic waters.
Synchronous foraging observed in chinstrap penguins
US researchers have been able to show that chinstrap penguins possibly synchronize their dives and hunts for krill, sharing their successes.
Are polar bears smarter hunters than previously thought?
A review study concludes that some polar bears are clever enough to use tools as weapons to hunt walruses.
First animal life as early as 890 million years ago?
Fossils from northwestern Canada may be remains of the oldest sponges found to date.
Mount Erebus provides power for science
Researchers have developed a way to power their instruments using heat from the Antarctic volcano.
Orca females also go through menopause
Researchers have found further evidence that female orcas enter menopause as they age, devoting more time to teaching their young.
Unique bumblebee discovered on Wrangel Island
The glacier bumblebee was first discovered on Novaya Zemlya in 1902. Now scientists have also discovered a population of bumblebees on Wrangel Island.
Franz Josef Land as the seasonal home of narwhals
After their second expedition to Franz Josef Land, Russian researchers assume that narwhals regularly visit the waters around the archipelago during the summer months.
Arctic ocean could be ice-free in summer by 2030
The duration of the ice season will be shorter due to later freezing and earlier ice opening. This is reported by Vladimir Ivanov, expert of the Lomonossov Moscow University.
Heat in Canada as a benefit for Greenland’s ice sheet
The heat wave that has kept much of Canada and the U.S. on edge for weeks has led to mass growth of the Greenland ice sheet.
Longyearbyen emits billions of microfibers
About as many microfibers enter the ocean each year from Spitsbergen’s main town as from Vancouver, mainly from hiking clothing.
Fast ice determines breeding success of emperor penguins
A new study has looked closely at the impact of Antarctic fast ice on emperor penguin colonies, analysing decades of data sets.
Giant petrels attack adult albatrosses in South Atlantic Ocean
Endangered Yellow-nosed Albatrosses are being attacked and killed by Southern Giant Petrels on Gough Island.
120 million years of intact geological record discovered
In the Yukon, scientists have uncovered a 120 million year geological record that is unique in the world.
Sea otters are equipped with “muscle heating”
Researchers discovered that the small marine mammals have a thermogenic “leak” in their skeletal muscles that helps them maintain body temperature.
New moss discovered in Antarctica
Indian scientists have discovered a new species of moss at Bharati Station in East Antarctica. Studies confirm that it is a new species.
Underwater seismometer listens to glacier movements
A new study shows that glaciers flowing into the ocean are responsible for seismic signals similar to slow earthquakes.
Focus on global plastic pollution
In a recent review article, scientists highlight consequences of weathering and degradation processes in plastics and warn of potentially irreversible pollution.
Climate Change makes Arctic Ozone Loss Worse
In spring 2020, the MOSAiC expedition recorded a record loss of ozone in the Arctic stratosphere. As evaluations now show, ozone depletion could intensify.
How young Weddell seals learn to swim
Before young Weddell seals can begin hunting on their own, they must learn how to navigate safely under the sea ice and get to their breathing holes.
Fossil baby teeth reveal dinosaur diversity in the Arctic
A research team has discovered fossils of baby dinosaurs, demonstrating that dinosaur diversity in the Arctic was higher than previously thought.
