water column and to increase the strength of the desired signal, SphericelTM
hollow glass spheres were distributed throughout the water column (Figure 24).
The spheres have the appearance of a white powder and a range of specific
gravity of 0.1-1.5 g/cc. During wave generation, distribution of white
pigmentation in the water column remains well mixed.
