Decoding the reverberations.

Figure 1. Segments of one of Common Offset Gathers
from the previous page : the offset is 714 m, the first segment represents the input, the last one - output.To testify for the correctness of the processing, a posteriori identification of multiples has been done. The identification is carried out with compressing of Common Offset Gathers with respect to the space scale: the resulting image of "an artificial medium" is easy interpretable: all of physical rays in such a medium should be close to the vertical (in spite of the real offsets are far from zero: the offset is 714 m). Now all of reverberations related to any pair of strong horizons (free surface, sea-bottom, "basalt") look like a family of "synclines" of near to equal "thickness" (along the time axis) and with common vertex.
NB! Certainly, the identification is rather conventional: just one of the relevant codes is indicated: see, e.g. peglegs (Figure 4): "301 "= "103", "302"= "203", and so forth. Note, that the see-surface index (0 ) is omitted, if it occurs just one time in a given code.


Figure 2. Common Offet Gather (714 m).
Underneath the sea surface (0) two strong horizons are mostly seen: sea -bottom (1) and "basalt" (2): see, e.g. the next Figure 3.

Figure 3. Intrabed reverberations, the 3rd group of multiples and related peglegs.
Again: 301 is the code which stands for 301 and 103.

Figure 4. Just "the 3rd group of primaries"- related peglegs are shown.
