The expedition Arctic Ocean 2025, blog post 7: A last hello and goodbye

The research school onboard the research ice breaker Oden has come to an end. In the evening the day before yesterday we did our last research station and deployed a mooring in the marginal ice zone, where the pack ice meets in the open ocean; a permanent buoy under the the surface that is tethered to the ocean floor and will stay there for the next years.

When science meets politics: Inside the stalled plastics treaty negotiations

This August, delegates from 183 nations gathered in a spacious UN hall in Geneva with a daunting task: to negotiate the world’s first legally binding treaty to end plastic pollution. More than 2,600 participants filled the conference halls, including government representatives, scientists, civil society groups, and industry observers. The mood was tense, hopeful, and, as the days dragged on, increasingly fractured. After nearly two weeks of talks, the negotiations adjourned without an agreement.

The expedition Arctic Ocean 2025, blog post 6: Polar bears, multi-beam sonar and examination

During this week it has become clear that we moved into the autumn freeze up. There is almost no open water around us at all anymore. Where open water was present previously, between the more solid ice floes, the ocean is now covered with a layer of new ice.

Mapping Deep Ocean Currents: Uncovering the Hidden Pathways of Overflow Waters

The recent SWERVE funded FAROX cruise, led by Léon Chafik on RV Skagerak, set out to explore how dense overflow waters move between the Nordic Seas and the North Atlantic. By collecting unprecedented measurements of temperature, salinity, currents, and turbulence, the team mapped deep currents and investigated their role in shaping the climate system.

The expedition Arctic Ocean 2025, blog post 5: We are alone now, it's colder and new ice is forming

Four weeks have now passed and there is less than two weeks left of our Arctic adventure. One can sense that people on board have started to realize this and react differently. Some refuse to think about it while others think about it all the time. This is human nature and the mood onboard is very good but it will be a special moment when we get back.
