- 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...

- 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
