We review statistical analyses of Lagrangian data from the ocean. These can be grouped
into studies involving single particles and those with pairs or groups of particles. Single …

The presence of coherent vortices makes observed mesoscale fields of the ocean resemble
two-dimensional turbulence. Using this analogy, a common definition of a coherent structure …

The Lagrangian separation distance between the endpoints of simulated and observed
drifter trajectories is often used to assess the performance of numerical particle trajectory …

Pair statistics are calculated for subsurface floats in the North Atlantic. The relative diffusivity
(the derivative of the mean square particle separation) is approximately constant at large …

We investigate the performance of standard stochastic models of single-particle dispersion
in two-dimensional turbulence. Owing to the presence of coherent vortices, particle …

A statistical analysis of surface drifter observations is used to compute eddy length and time
scales and eddy diffusion in the Southern Ocean. Eddy diffusion values of the order of 10 4 …

Northwest Atlantic Ocean in: Journal of Physical Oceanography Volume 34 Issue 8 (2004) …

The surface transport properties in the Adriatic Sea, a semienclosed subbasin of the
Mediterranean Sea, have been studied using a drifter dataset in the period December 1994 …

We study the evolution of vortex statistics in freely decaying two-dimensional turbulence at
very large Reynolds number. The results obtained here confirm that the peak vorticity inside …
