Fig. 6: Example of particle tracking providing advection timescale information.

Example of offline particle tracking for 7 days from 30th August 2021 at 0:00 using JCOPE-T DA surface velocities. The colours represent each day. The black dots are the initial points. The grey contours represent the seafloor topography. The areas of the magenta rectangles correspond to the areas shown in Fig. 7. Source data are provided as a Source Data file.
