Description of the thesis topic

Ocean energy balance is currently receiving considerable attention from oceanographers. Energy sources due to wind stress and heat fluxes are well identified. Yet, much less is known about energy sinks.The aim of our project is to identify a new pathway for energy dissipation in the ocean, involving turbulent dynamics of boundary currents such as the Gulf stream or the Kuroshio. This practical problem is related to a central fundamental question underpinning the longstanding issue of energy dissipation in turbulent flows. We hypothesize that western boundary current may lead to the formation of extremely strong vortices close to the coast, with far reaching consequences on ocean currents at basin scale. We propose to hire a PhD candidate to tackle this issue using both cutting-edge numerical ocean models and modern tools of theoretical physics applied to turbulence.

Work Context

The PhD candidate will work at the physics laboratory of ENS de Lyon and and IGE Grenoble, in the framework of a multidisciplinary project between physics and oceanography, funded by MITI-CNRS.
