“…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).…”
