This is different from freshwater flowing east and south-west of Greenland, that more easily enters the Labrador Sea.
This result highlights the importance of considering the different pathways fresh waters follow in the subpolar North Atlantic when evaluating their future influence on the region.
In line with previous studies, this suggests that the fresh Baffin / Hudson Bay waters are unlikely to directly affect the Labrador Sea interior.
However, they might have a more indirect influence of on the interior subpolar North Atlantic as they recirculate in the Subpolar Gyre.
The drifters remained on the Labrador shelf, along the Canadian coast, until they reached Flemish Pass, south of the Labrador Sea convection region.
There, the majority of the drifters left the shelf and headed north-eastwards, apparently recirculating into the Subpolar Gyre
Here we specifically investigated how the relatively fresh waters from west of Greenland and Baffin Bay circulate over and away from the Labrador Shelf.
We use trajectories from surface drifters deployed in the last years around Greenland, which provide new data in previously undersampled regions
Why does it matter?
In the coming decades, increasing amounts of Greenland and Arctic waters will enter the North Atlantic, potentially affecting important ocean processes. These waters first flow along the Greenland and Canada coast and their pathways into the open ocean are not fully understood.
🌊 New study out on freshwater pathways in the subpolar North Atlantic:
With @eleanorfrajka.bsky.social and @foukalpoint.bsky.social we used surface drifters to describe the circulation of Baffin Bay and Hudson Bay waters over and away from the Labrador Shelf

💡 Good to know:
If you are already going to present your work in a scientific session, you can also submit an additional abstract to an EOS session.
www.egu24.eu/guidelines/e...
Feel free to contact me if you have questions, and share this call for abstracts with colleagues who could be interested!
In particular it'd be great to get perspectives from political/social scientists on the topics addressed by this session.
Last year's edition of this session was very successful, with 22 talks and posters, and a full room throughout, demonstrating the interest for these topics in the geosciences community. The full list of abstracts from last year can be found here: meetingorganizer.copernicus.org/EGU24/sessio...
We're inviting abstracts that present, analyze and discuss different ways geoscientists engage with the climate and ecological crisis beyond "research as usual", from outreach to activism, from reducing the carbon footprint of our activities to rethinking the way we practice science.

🌍 Climate action in academia #EGU25
Do you research the role of academics / universities in communicating about the climate crisis? Are you an earth scientist involved in climate outreach / activism?
