Joseph Lacasce: Relative Dispersion in the Nordic Seas

The mixing of temperature and pollutants in the ocean can be studied by examining how pairs of particles, deployed together, separate in time and space. Here we consider a recent field experiment in which 120 satellite-tracked surface drifters were deployed in pairs and triplets off the Norwegian coast. We discuss the observed dispersion, and how this can be rationalized within the framework of the theory of two-dimensional turbulence.
