Tools used:
* WATERS Wavelet Analysis for Timetracking Eddies
Wavelet analysis performed on relative vorticity calculated from Symphonie POC modelled currents
Other uses of WATERS can be found on Dr Doglioli 's webpage.
* ARIANE is a computational tool (Fortran 90/95) that is dedicated to the offline calculation of 3D streamlines in the output velocity field of an Ocean General Circulation Model (OGCM) such as OPANEMO, ROMS, Symphonie and any ocean model whose equations are based on volume conservation.
see ARIANE 's webpage realized by Nicolas Grima at LPO for more information.
Modelling 


The WATERS package was used in order to track the eddy or filament structures of the Gulf of Lion. It was applied to horizontal maps of relative vorticity, calculated from the velocity outputs of the SYMPHONIE model (data provided by C.Estournel and P.Marsaleix, POC, Toulouse). 
The ARIANE toolkit has been coupled with de SYMPHONIE model and has provided both qualitative and quantitative numerical trajectories.
