EXPEDITION 2025: Tracing Arctic Waters and the Future of Climate

The expedition connects to polar research by tracking Arctic-sourced water masses – formed through cooling and sea ice processes – as they travel and transform en route to the deep Atlantic. These dynamics are closely linked to climate change, both in the Arctic and globally.

Using gliders, current meters, and microstructure sensors, the team will investigate how different pathways converge and mix, and how this contributes to the overflow through the Faroe Bank Channel – the deepest passage across the Greenland-Scotland Ridge.

The expedition will help:

• Improve understanding of AMOC dynamics
• Predict climate impacts related to Arctic changes
• Strengthen Swedish contributions to international polar research

All expedition data will be made publicly available via SMHI within two years.
