The problem of sound propagation in a shallow sea with a rough sea bottom is considered. A random matrix approach for studying sound scattering by the water?bottom interface inhomogeneities is developed. This approach is based on the construction of a st...

Bottom formations known as pockmarks basically arise due to extensive gas emission. Active pockmarks are characterized by exceptionally high gas saturation and substantially reduced sound speed. The latter circumstance leads to strong attenuation of soun...

The depth velocity model is a critical element for providing seismic data processing success, as it is responsible for the times of waves? propagation and, therefore, prescribes the location of geological objects in the resulting seismic images. Construc...
