The principal uncertainty in the determination of the amount of sediment entering the Sound arises from a lack of information about the composition of the materials being eroded from the north shore or Long Island. Field work and sampling along this shore are needed. Before it is incorporated into the permanent bottom of the Sound, sediment is available for resuspension for a number of years. The amount and frequency of resuspension depends on both physical and biological factors, which can... 

Rapid erosion of the cliffs on the north shore of Long Island over the past 90 yr has been deduced from comparison of old and new maps (D. S. Davies, E. W. Axelrod, and J. S. O Connor, undated report. Marine Sciences Research Center, State University of New York, Stony Brook, New York). Because the areas of greatest erosion are quite localized and the composition of the material making up the cliffs has not been systematically sampled, a reliable estimate of the amount of silt-clay sediment entering the Sound from this source cannot be made now. There is a strong possibility that it is significant but nevertheless smaller than the river input.
