The above movie was made by Matthew Spydell. It shows May 3rd ebb tide drifter trajectories from the RIVET experiment at New River Inlet. Bathymetry is shaded. Land regions are in gray. The bar on top indicates elapsed time (in hours) since the start of the release. For more information on this release look at this blog entry.  This movie contains a lot more drifter information though.  In the original blog entry the drifters got out of radio contact so we couldn’t track them in real time.   But they log their GPS positions onboard the drifter memory.    What was interesting (as noted in the original post)  is that there was no indication that the drifters going back  onshore during the flood tide.
