A simple empirical estimate is presented for predicting the variation with depth of a scalar concentration field in the far wake of a submarine operating beneath the ocean surface. By examining near surface and intermediate depth diffusion and turbulent dissipation data, it is shown that the horizontal diffusion coefficient decreases by a factor of from 2.2 to 2.5 in the depth regime between 10 and 300 meters. Semi-empirical equations for the strength of the concentration field from instantaneous and continuous sources are developed.
