Abstract : The factors in the marine biological environment that pertain to underwater sound were investigated and are reported. Organisms affecting sound attenuation and reflection are identified and studied. The distribution of such organisms in space and time to gain a predictive understanding of their fluctuations in critical areas of the ocean is discussed. Specifically, the U.S. Navy submarine SQUAW (No. 29) was examined and a report was made on the biological fouling present after approximately 5 years of submergence at a depth of 200 feet in the deep oceanic environment. The fouling organisms are identified and their numbers are estimated. Their distribution on the hull is described. (Author)
