We review a series of experimental investigations of anomalous
transport in quasi-geostrophic flow. Tracer particles are
tracked for long periods of time in two-dimensional flows
comprised of chains of vortices generated in a rapidly rotating
annular tank. The tracer particles typically follow chaotic
trajectories, alternately sticking in vortices and flying long
distances in the jets surrounding the vortices. Probability
distribution functions (PDFs) are measured for the sticking
and flight times. The flight PDFs are found to be power laws
for most time-dependent flows with coherent vortices. In many
cases the PDFs have a divergent second moment, indicating
the presence of Levy flights. The variance of an ensemble
of particles is found to vary in time as *sigma^2 ~ t^
z*, with *z > 1* (superdiffusion). The dependence
of the variance exponent *z* on the flight and sticking
PDFs is studied and found to be consistent with calculations
based on a continuous time random walk model.
