In planning for the drifter releases, Matt Spydell has put together this movie for the entire 2009 simulation: Aug 15 – Nov 15 using the 200m and 66 m (north and south) grids. The movie is long, you can speed it up 2x using the tools button.  The top panels are finite-time forward Lyupanov exponents for times at 2, 4, 6, and 10 hour trajectories with bathymetry contoured at 25 m intervals until 150 m depth and then 50 m intervals.  The bottom panels are vorticity, divergence, Okubo-Weiss parameter, and perturbation temperature all at the surface (top most ROMs bin).   In all bottom 4 panels the temperature deviation is contoured.   The fronts are really clearly visible.   The thick arrow indicates surface current off Pt Sal and a thin arrow indicates wind velocity (note, they are scaled differently).   We are using this information to plan our drifter releases.
