Abstract : A computer program has been developed for calculating the propagation loss of underwater sound into the region of the shadow zone. The calculations are based on a composite propagation scattering model. The computer program has been written partly in FORTRAN IV and partly in NELIAC. Copies of this program are available to interested parties. (Author)
