The polar retrospective – size, gender, Greenland
While last week a study dispelled a historical myth about gender differences in size, the link between a historical scandal and the issue of women’s and human rights was discussed in Denmark.

The new EU project POLARIN will provide 50 international institutions with access to research infrastructure in the polar regions over the next five years.
The exact reason that rivers in northern Alaska have turned orange is unknown, researcher tells Polar Journal.
A new discovery shows that male sea spider take care of their young in the icy waters of the Antarctic.
Mammals introduced to islands benefit from the “surprise effect” on an evolutionary scale, causing the disappearance of many seabirds. On Kerguelen, hyperspecialized cats threaten the chicks of great albatrosses.
The highly pathogenic bird flu has reached the Antarctic: the H5N1 virus has been detected in two dead skuas found on the Antarctic Peninsula.
Antarctic krill is only slightly contaminated with microplastics and is therefore well suited for monitoring the contamination of the Southern Ocean with microplastics.
SLF technician Matthias Jaggi reports on his expedition to the Antarctic. Part four: last experiments, packing – and crêpes for 52 people
Researchers from the Alfred Wegener Institute (AWI) discovered that apparently little nutritious jellyfish make up a considerable part of the diet of amphipods during the polar night.
A northern elephant seal bull showed highly unusual behavior when he saved a pup from drowning in California.
The crew of the Sea Shepherd vessel “Allankay” recently documented how six supertrawlers sailed through a large group of hundreds of feeding whales to catch huge amounts of krill.
The release period after the breeding season can quickly resemble a sea voyage where the penguins have to choose one route over another… a story of compromise.
Four emperor penguin colonies have been discovered thanks to satellite images. These colonies, identified for the first time, each number fewer than 1 000 pairs.
Why are microplastics found in the polar regions almost exclusively in fibre shape? The latest experiments and simulations provide the answer: fibres can be transported much further in the atmosphere than particles with a different shape.
Analizing ice cores shows that heavy metals have been transported to the heart of Antarctica from both geographically and temporally distant regions.
First announced last spring of the southern hemisphere, highly pathogenic avian influenza HPAI is now affecting five of the 14 species tested in South Georgia. A few suspected cases near the Antarctic Peninsula suggest that the disease is still spreading.
Despite the strong seasonal fluctuations in living conditions in the Arctic, the animals living on the seabed of the Arctic Ocean are largely unaffected by the seasons.
Southern elephant seals don’t fast completely during the drastic moulting period, but they may well go into the water, drink and perhaps even hunt, contrary to what has been established so far.
Male Southern elephant seals are extremely picky when it comes to food, with each animal apparently having its own favorite food.
For the first time, researchers detected chemicals from sunscreen, perfume, etc. in the snow near Ny Ålesund on Spitsbergen.
Currently, SLF technician Matthias Jaggi is working at the Concordia Station in the middle of Antarctica, researching snow. In his blog, he reports on his work and life at 3,000 m above sea level.
In Svalbard, freshwater fish benefit from slightly warmer water than usual in the lakes they inhabit, which could be increasingly beneficial for fishing, at least as long as the glaciers remain.
Calories are needed to combat the cold, and the reindeer have to work so hard to store up energy for the winter that they have to sleep ruminating during the summer.
Along with climate change, environmental pollution is one of the most pressing problems in the Arctic and Antarctic and has increasingly become the focus of research in recent years.
