Abstract:

This memorandum is concerned primarily with a second evaluation of data reported by the Narragansett Bay Marine Laboratory. The data itself are related to their work on the sediments of Narragansett Bay. The physical parameters of interest to our problems are densities of the sediments and their porosities. The densities are bulk densities in the dry state and in situ. The porosity we are concerned with is the ratio of the voids, presumably filled with water, to the wet bulk volume. These parameters are of interest to us because they are related to attenuation, reflection, and transmission of sound at one boundary of the ocean. What can learn of them is therefore of importance.
