Abstract : The program includes studies on the sound reflection and attenuation caused by the presence of planktonic organisms and members of the nekton. These studies are closely aligned with the sonic devices used by the Navy. Identification of these organisms, their behavior and their geographical distribution is necessary in order to predict their occurrence and to separate them from valid USW targets. Investigations of soniferous animals are necessary for the proper identification of the sounds produced with the animal source and to predict the occurrence of sounds on the basis of geographical distribution and behavior of the animals. Another major area of programmatic interest is the means by which animals are able to utilize echolocation.
