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%. https://t.co/iSZI8WU37W

A comprehensive modeling study shows how subglacial meltwater triggers an additional summer bloom of phytoplankton in Disko Bay. At the same time, the climate-relevant carbon sequestration increases...

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. https://t.co/wtJ8WzkfFQ

In Canada’s Yukon, the Tintina Fault has the potential for an earthquake exceeding magnitude 7.5. Dawson City lies dangerously close to the epicentre and could be severely affected by the shaking.

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 an ETA. But getting one is currently difficult as the system is not operational yet #Antarctic #tourism
https://t.co/MelsNV3n90

The Government of South Georgia and the South Sandwich Islands had planned to implement a new ETA system for visitors but had to delay these plans now.

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. #Arctic #fox #map #inuit

It’s all in the bones, at least when you are looking into the past of Arctic animals and scientists of the University of Bournemouth and University of Oslo were particularly lucky in finding 75,000 years old bones in a Norwegian Arctic cave #DNA #climate

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. https://t.co/0WX0n48g4C

Here's two more visualizations of the production-ready #PolarClass4 Multi-Purpose #Icebreaker (MPI) that our consortium with @BollingerShip, @RMCFinland and @Seaspan is now offering to the @USCG with delivery within 36 months of contract award.
The Multi-Purpose Icebreaker (MPI) design was developed from the keel up for North American coast guard operations. It exceeds all Arctic Security Cutter requirements specified in the recent RFI and supports all eleven @USCG statutory missions. ...and it looks good! #ARC146

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 👉 https://t.co/4rFoS20vu5

Icebreakers are essential for polar infrastructure. 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 , construction of new #icebreakers faces several issues https://t.co/O5EtfPsqtc
polarjournal.net
The US icebreaker program is struggling amidst high costs and delays while a Finnish-Canadian consortium could help but is hampered by the current trade policy of the US government.

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
