Acoustic ray paths in the ocean are known to exhibit significant horizontal deflections after repeated reflections from the bottom. The effect may be quantitatively and qualitatively observed through a ray trace model which permits a change in direction of the vertical plane of propagation as a function of bottom slope and grazing angle. ECTRACE is a family of computer programs which traces a bundle of rays in three dimensions and utilizes bottom depth values as a portion of its input. Included are related programs which develop sea bed models from digitized bathymetry data or synthetic bathymetry functions. Author
