There is good agreement between trajectories from the 2018 experiment computed here and cLCS from  \citet{Duran_2018}. Trajectories from the east move across weak cLCS that are deformed as chevrons within the Yucatan shelf, while trajectories from the northwest move along strong cLCS until they meet within the initial-position polygon (Fig. \ref{521863}). The advection of cool SST coincides with most trajectories (Fig. \ref{581122}c) in crossing weak cLCS that, deformed as chevrons, indicate the direction of weak transport.  We note that, unlike LCS, cLCS are not proper transport barriers. The chevrons reported here are similar to what was found in \citet{Gouveia_2021}, where along-slope SST advection happens through weak cLCS deformed as chevrons, while cLCS with relatively strong climatological attraction indicate transport barriers.
