The Arctic Ocean Dynamics
Workshop 2025
24-26 November 2025 | Ecole normale superieure - PSL
Come reunite with your Arctic research colleagues for stimulating scientific exchange in the vibrant city of Paris. The aim of this workshop is to survey key theoretical ideas, identify knowledge gaps and stimulate further advances in our understanding of Arctic Ocean dynamics. We hope you will join us!
Program
This year's program features four themes over three days:
- Arctic Ocean Circulation and Structure — Exploring the spatial patterns, variability, and dynamical drivers of Arctic Ocean circulation and mixing.
- Sea Ice–Ocean Coupling and Polar Connections — Interactions between sea ice and ocean processes, from floe-scale coupling to large-scale polar variability.
- Freshwater and Overturning Circulation — Linking freshwater pathways, stratification, and overturning dynamics to the evolving Arctic–Atlantic system.
- Beaufort Gyre Dynamics and Variability — Processes controlling the stability, structure, and energy pathways of the Beaufort Gyre under changing wind and ice conditions.

Directions
Transportation
- By Plane: Fly into Roissy–Charles de Gaulle or Orly. From either airport, you can take the RER B to Luxembourg station, or a taxi.
- RER B from the airport: Trains run every 10–15 minutes from both airports. The ride to Luxembourg station takes about 35–40 minutes, and the fare is 13€. Luxembourg station is an easy 10-minute walk from both the workshop hotel and the department.
- Taxi from the airport: Fares to central Paris are fixed. The maximum (all included) is 65€.
-
By Metro:
The nearest stations are Luxembourg (RER B), Place Monge (line 7), and Cardinal Lemoine (line 10). All are about a 10-minute walk from the workshop venue.
