New lithological, palinological and chronological data obtained through the study of bottom sediments from four small lake depressions on the Pomor Coast, Onega Bay, White Sea are presented. The integrated study of bottom sediments from lakes lying at different elevations in the northeastern part of the Sumozersky moraine complex and the White Sea lowland allowed to establish the time and features of their deposition, to distinguish the palaeoclimatic stages in the development of the environment on the Karelian Coast of the White Sea during the Late Glacial and Holocene.
