Translations:Water reverberations/11/en

In summary, the source and receiver locations are just below the water surface. Source energy travels down to the water bottom, from which it is reflected. The reflected upgoing energy proceeds toward the water surface, where it is recorded as a primary reflection. However, this upgoing energy also is reflected from the surface and then continues to bounce back and forth in the water layer. These multiple reflections within the water layer make up the water-layer reverberation. Such reverberations are generally undesirable because they obscure reflections from deeper horizons. Figure 8 shows the raypaths for the water reverberation. (For clarity, the raypaths have been drawn as slanting lines, although in our normal-incidence model, they are perpendicular to the two interfaces.)
