About the Position/Job
The CNRS – Laboratoire d’Études en Géophysique et Océanographie Spatiales (LEGOS) is offering a full-time Researcher position focused on the study of scale interactions in the ocean through theory and numerical modelling, as part of the MOTIONS project. This role centres on understanding small- to large-scale ocean processes, especially in regions like the Strait of Gibraltar, using the CROCO-NS numerical model. The project aims to enhance next-generation ocean models by integrating high-resolution, non-hydrostatic simulations. The work involves developing diagnostics, analysing turbulent cascades, and advancing the concept of potential vorticity in non-hydrostatic regimes. Based at LEGOS in Toulouse, this position allows collaboration with leading researchers across France while contributing to a scientifically significant initiative with global implications for ocean dynamics.
