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!


Arctic, Gianluca Meneghello

Program

This year's program features five 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.
  • Arctic meets Antarctic — Two talks aimed at bridging the communities studying the Antarctic and Arctic Oceans.
