Polar Journal is back! With fresh energy and a new team, we’re bringing you fascinating stories, behind-the-scenes insights, and all the latest from the world’s polar regions. www.polarjournal.net

In Greenland’s Disko Bay, subglacial meltwater lifts nutrient-rich deep water to the surface, driving a summer phytoplankton bloom. That’s good for the food web, but the climate effect is modest: the modeled CO₂ uptake rises by only about 3%. polarjournal.net/subglacial-m...

Time, a changing climate, and humans are the connecting factors of our latest Polar Retrospective. We thereby take you to islands in the Southern Ocean and into the Arctic region, just as we love doing, bringing you stories from both sides of the planet #science polarjournal.net/the-polar-re...

The 1,000-kilometre-long Tintina Fault runs less than 20 kilometres from Dawson City. New research by the University of Victoria shows it has produced major quakes in the geologically recent past — and may be building toward another exceeding magnitude 7.5. polarjournal.net/forgotten-fa...

When traveling to the UK, you need an ETA. But what’s new is that if you travel to the British Overseas Territory of South Georgia, you also need to have an ETA. But getting one is currently difficult as the system is not operational yet. #Antarctic #tourism polarjournal.net/launch-of-ne...

New, new, new, that’s our take from last week’s information coming from Antarctica and the Arctic. But not all of them were good news, unfortunately. Especially from Svalbard, we got some worrying news about Arctic foxes. polarjournal.net/the-polar-re... #Arctic #map #island #fox #avianflu #inuit

It’s all in the bones, at least when you are looking into the past of Arctic animals and scientists of the @bournemouthuni.bsky.social and @uio.no were particularly lucky in finding 75,000 years old bones in a Norwegian Arctic cave. #DNA #climate #Arctic polarjournal.net/our-dna-anal...

Arctic security is at the top of priority lists of several European nations. We explore the reasons for countries like Germany and France to invest more into their Arctic security strategies. polarjournal.net/a-shifting-h... #Arctic #politics #security #Europe #defense #USA

Male leopard seals spend hours each day calling underwater during breeding season. A new study shows their vocal patterns are simple, repetitive and remarkably similar to human nursery rhymes. polarjournal.net/rockabye-bab...

While it seems easy to create a MPA in polar regions on a map, the reality is more complex. Two new studies that seem to contradict each other, are actually showing which strategies future polar MPAs should take. polarjournal.net/do-marine-pr... #conservation #Arctic #Antarctica

Looking back, February 2025 was too mild in many regions of the Northern hemisphere, especially on Svalbard. Here, scientists found areas that looked like springtime rather than winter. Read more about it here 👉 polarjournal.net/on-svalbard-... #climate #svalbard #warming #science

The strongest earthquake recorded this year so far (8.8) has hit the east coast of Kamchatka and authorities in several countries have issued tsunami warnings that reach from Alaska even to East Antarctica. polarjournal.net/tsunami-warn... #Alaska #earthquake #tsunami #Antarctica

The end of Scott and his companions on their ill-fated expedition to the South Pole is still debated: did the blizzard occur or not? A new study sheds light on this long debate in favour of Scott. #Antarctica #history #expedition #weather polarjournal.net/so-robert-fa...

Last week saw some hot topics coming from the polar regions and we managed to catch a few for you. Whether you are interested in technics, science or conservation, you’ll find it in our team’s latest retrospective #Arctic #Antarctica #science #technical #polarbear polarjournal.net/the-polar-re...

When vacation photos from the far north show a glacier at 30°C, it's clear that something is wrong with the climate. In her new blog, @iceblogger.bsky.social asks why so many don't care and whether we can regain control of the situation. iceblog.org/2025/07/22/c... In German exclusively with us.

Arctic foxes are slowly recovering in northern Europe – but inbreeding remains a threat. A new report shows that genetic diversity isn’t keeping pace with population growth. Conservationists now aim to improve gene flow between fragmented groups. polarjournal.net/protecting-a...

Icebreakers are essential. However, the #USA has been struggling for more than a decade to modernize its fleet. While a newly acquired vessel enters the service of the @uscg-official.bsky.social construction of new #icebreakers faces several issues. polarjournal.net/the-complex-... #Arctic #ships

We've almost forgotten it, but Wordie wasn't always a bay: it was once an ici shelf, and its slow disappearance is a typical example of the powerful phenomenon of #glacier collapse in #Antarctica, fuelled by human activity and political inaction. #Climate polarjournal.net/wordie-chron...

Today, our team dives deep into the Arctic, from the deep sea to the deep earth to deep defense politics in their retrospective of last week’s happenings in polar regions. All just one click away. polarjournal.net/the-polar-re... #Arctic #politics #science #iceland #France #ocean #volcano

Could life have survived the “Snowball Earth” ice ages in meltwater ponds near the equator? A new Antarctic study finds diverse microbial life in ephemeral ponds on the McMurdo Ice Shelf — offering clues to how early eukaryotes endured one of the coldest chapters in Earth’s history.

China's economy views the Arctic as crucial to securing its global economic power. At the same time, however, Chinese scientists are loudly calling for the international regulation of shipping in the Arctic. A paradox? #Arctic #economy #china #science polarjournal.net/chinas-arcti...

Orcas are already fascinating with their ying and yang ☯ colors, but the more we learn about them, the more remarkable they are. These giant #dolphins are the true apex #predator of the ocean, preying on great white sharks and other lesser predators. polarjournal.net/drone-footag...

Never-before-seen images filmed in #Antarctica show traces of #anchoring on a deep, untouched #seabed. Without concluding that there is a definite impact, a study invites us to consider the potential effects of human activities on these fragile ecosystems. 🦋 polarjournal.net/do-antarctic...
