Abstract
Since 1959, an acoustic investigation has been made of the characteristics of scattering layers in the deep ocean. Marked variations of scattering strengths and layer depths were observed as a function of time of day, frequency, and location. The greatest variations in scattering strengths with location took place near oceanographic boundaries. Sound sources for the experiments were explosives fired near the surface. Measurements were made with both omnidirectional and directional wideband receivers. The measurement and analysis techniques are illustrated using data collected in the North and South Atlantic and in the North Pacific.
