The subject of this article represents results of scientific studies in 2018–2019. The studies indicate that the phenomena of gas saturation of bottom sediments are often observed within the Lake Onega. Basically, this occurs in the mouths, while in the open part of the lake the degree of gas saturation of the sediments is incomparably less. According to the geo-chemical studies, numerous signs confirmed the predominantly biogenic origin of gases.
