Introduction: The method for interpreting marine seismoacoustic data used to study the engineeringgeological conditions of a fragment of the upper part of the section of the Terek-Caspian trough is described. Materials and Methods: The principles for separating the main groups of data, in which structural horizons are divided into sections with different physical parameters, forming anomalous zones of the "bright spot" type were described. Results and Discussions: The stages of data interpretation and analysis of seismoacoustic anomalies at different levels of the Terek-Caspian trough of the northern Caspian were considered. Features associated with the presence of gas on seismoacoustic records were identified. A lot of attention was paid to the identification of anomalous zones. Each zone was confined to the corresponding reflection horizon. A comparison with similar nearby areas was made for the identification of the specifics of the geological setting in the upper part of the crustal section. Conclusions: An optimal sequence of interpretation of marine seismoacoustic data was formed, which allowed to obtain a high-quality final material intended for solving engineering-geological problems.
