摘要：
The article presents the results of seismoacoustic studies carried out in Petrozavodsk Bay of Lake Onega. The goal was to study a near-surface geological section. Seismoacoustic studies were done by the reflection method in a modified ultra-high-resolution seismic survey. The data were office processed and interpreted: five seismic complexes were identified and correlated with information on the lake's structure, culminating in maps of all five identified reflectors covering all of Petrozavodsk Bay. It was possible to estimate the abundance and thickness of sediments corresponding to each complex.
