**Lagrangian Time and Space
Scales**

The Lagrangian autocorrelation function was computed for each drifter velocity
component, and then integrated from zero lag to the first zero crossing of the
autocorrelation to give a Lagrangian integral time scale. The Lagrangian space
scale was then found by multiplying the integral time scale by the rms velocity
for each component.
