A two-dimensional, convective-dispersive transport model was used to predict bounds on the expected long-term time-averaged dilutions for wastes disposed of at the 106-Mile Ocean Disposal Site (between 38 deg 40 min and 39 deg 00 min N, and 72 deg 00 min and 72 deg 30 min W). Potential concentrations of wastes near the outer continental shelf were of particular interest because of the presence of commercial and sportfishing grounds. The major model assumptions were (1) the wastes were completely mixed vertically and remained in the upper mixed layer, (2) the expected center of mass of a discrete dump of material was convected from the disposal site with the mean horizontal current, (3) the expected dispersion of a discrete dump of material about its center of mass was determined by the variance and correlation structure of current velocities, and (4) the expected long-term time-averaged plume can be estimated by superimposing the expected distributions of the individual dumps.
