“…For a random process the integral converges as R ii (t) drops to zero. In practice, the integral time is usually calculated by integrating the autocorrelation function up to the first zero crossing time t Z (Poulain and Niiler, 1989;Zavala Sansón, 2015)…”

We present single-particle statistics of a large data set of surface drifters released in the southern Gulf of Mexico. The study is focused on the probability density functions of velocities, Lagrangian scales and absolute dispersion estimates. The probability distributions display a non-Gaussian shape with extended tails. It is shown that the long tails are mainly associated with the Campeche gyre (an intense cyclonic circulation frequently formed in the region) and, to a lesser extent, with a flow along the western margin of the basin. The results are discussed in light of previous studies on ocean dispersion that have reported Gaussian and non-Gaussian distributions in other regions.

“…Despite the baroclinicity of the oceanic currents and eddies, most concepts from the 2D turbulence theory were shown to largely apply to geostrophic turbulence (Charney, 1971; McWilliams, 1989; Rhines, 1979), and the theory of particle dispersion in 2D turbulent flows has provided a solid background for the study of passive tracer evolution in the ocean (Babiano et al., 1990; Batchelor, 1952; Bennett, 1987; Kraichnan, 1967; LaCasce, 2008; Lin, 1972; Lundgren, 1981). Lagrangian experiments, involving the release of large numbers of satellite‐tracked drifting buoys in pairs or triplets, and studying their relative movement as turbulent advection separates them, have successfully applied these concepts to reveal the turbulent regimes occurring over a variety of time and space scales in the ocean (Colin de Verdiere, 1983; Davis, 1991; LaCasce & Ohlmann, 2003; Ollitrault et al., 2005; Zavala Sansón, 2015, among many).…”

At scales larger than a few kilometers, the ocean motion is essentially horizontal, and the fate of tracers is primarily determined by lateral stirring (horizontal at the surface and isopycnal at depth) by eddies. Despite the baroclinicity of the oceanic currents and eddies, most concepts from the 2D turbulence theory were shown to largely apply to geostrophic turbulence (Charney, 1971;McWilliams, 1989;Rhines, 1979), and the theory of particle dispersion in 2D turbulent flows has provided a solid background for the study of passive tracer evolution in the ocean (
