An exact integral expression for the Stokes' drift of diffusive particles produced by an arbitrary wave form is derived. Asymptotic expressions are given in the large-diffusion and small-diffusion limits as a function of the Peclet number. The integrals are evaluated analytically for a square wave and an impulse wave.
