One of the goals of the Latex10 field experiment, conducted during September 2010 in the Gulf of Lion (northwest Mediterranean), was to mark a dynamical mesoscale feature by releasing a passive tracer [sulfur hexafluoride (SF6)] together with an array of Lagrangian buoys. The goal was to release the tracer in an initial patch as homogeneous as possible in the horizontal, and to study its turbulent mixing and dispersion while minimizing the contribution due to advection. For that, it was necessary to continuously adjust the vessel route in order to remain as closely as possible in the Lagrangian reference frame moving with the investigated mesoscale structure. To accomplish this task, a methodology and software were developed, which are presented here. The software is equipped with a series of graphical and user-friendly accessories and the entire package for MATLAB can be freely downloaded (). specialized Dispersion Lagrangian circulation transport Ship observations Tracers Experimental design Software MEDITEREANEE GOLFE DU LION 032 122 30 8 1940-1950 2013 0739-0572 https://www.documentation.ird.fr/hor/fdi:010060626 10.1175/jtech-d-12-00183.1 0739-0572 [F B010060626] https://www.documentation.ird.fr/hor/fdi:010060626 https://www.documentation.ird.fr/intranet/publi/2013/09/010060626.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2013-10-02 2017-08-23 fdi:010060626 fre
