Section: Application Domains

Ocean dynamics, upwelling

Ocean dynamics from remote sensing data is studied in collaboration with LEGOS CNRS Laboratory in Toulouse (SYSC $O_{2}$ ) team, with CRTS and Rabat University in Morocco. The following thematics are studied:

Large time series analysis on global synoptic ocean data to provide fine characteristics of Ocean turbulence, analysis of altimetry data and ocean/atmosphere exchanges (supported by ICARODE project and submitted LEFE-EC2CO IMECO project).
Upwelling, Lyapunov exponents and Lagrangian Coherent Structures (supported by TOUBKAL project).
