Abstract

We present the results of seismoacoustic works carried out in the Petrozavodsk Bay of Lake Onega, the goal was to study a near-surface geological section. Seismoacoustic investigations were presented by the reflection method in a modification ultra-high resolution seismic survey. During the office work, the data were processed and interpreted, in which five seismic complexes were identified and correlated with the information about the lake structure. The result of the work was the maps construction of all five identified reflecting horizons covering all Petrozavodsk Bay. It was possible to estimate the sediments abundance and thickness corresponding to each complex.
