Abstract:
The realisation of seismic profiles with the seismic reflection technique for geophysical mapping of deep waters is greatly affected by the attenuation of the amplitude of the seismic signals received during propagation. This type of information is of particular interest to designers of marine information and communication systems. The purpose of this study is to directly detect the present-day attenuation of a single sound impulse in seawater, by considering the interference that is created during the acquisition of the seismic signals. This impulse, produced by the boomer seismic source, appears like a 'slap' generated in seawater, has defined characteristics, and is reproducible with good precision.
