Lagrangian Statistics Diffusivities and Lagrangian integral length and time scales were calculated from the drifter tracks and the two sets of numerical trajectories in both the zonal and meridional directions. Definitions and details of these statistics are provided in Appendix B. In all cases, the minimum number of observations used in these calculations per bin is greater than or equal to 400.
