ABSTRACT
We examine multiple particle statistics from surface drifters deployed as part of the SCULP program in the northern Gulf of Mexico. The results suggest two dispersion regimes: one in which particles separate exponentially in time for scales less than the deformation radius and one at larger scales in which particle separations increase with a power law dependence on time. In terms of 2-D turbulence, the first regime is consistent with a local enstrophy cascade and the second with an inverse energy cascade. Both two and three particle statistics are considered.
