Аннотация:New high-resolution seismo-acoustic data collected from the abyssal plain and from the foot of the continental slope with uninhabited autonomous underwater vehicle (AUV) allowed the identification of regional sedimentary processes formed its present morphological and structural image. The geological interpretation of the new data shows recent activity of the gravity, lithodynamic, erosion and neo-tectonic processes in deep water areas of the Black sea. All of these processes are of significant importance in formation of upper part of the section and are a major geologic hazards for different submarine installations.
