Abstract
Acoustic scattering from inhomogeneities in the body of the ocean is discussed for both back-scattering and for one-way propagation effects. The main theoretical and experimental descriptions concentrate on the smaller scatterers, especially fish, since internal waves and other wave motions will be covered else-where. A great variety of effects is listed, together with their significance for the scatterers themselves and for the resulting sonar limitations.
