We consider the rate of spread of a body of passive tracers moving under the influence of a random evolving vector field.

The vector field is of a type used as a model for ocean currents and was introduced by Kolmogorov. The rate of growth of the diameter of the body is of interest for practical reasons (such as in problems of pollution control) and we specify its rate of growth.
