Some results of the joint study of Quaternary sediments on the White Sea coast and ground to reconstruct paleogeographic events of its development in the Late Neopleistocene - Holocene boundary

The work is devoted to clarifying the history of the development of the White Sea in the Late Neopleistocene-Holocene by combining land and sea research in one project. The work was carried out in the Kandalaksha Bay of the White Sea, on the Solovetsky Archipelago and adjacent water area, and on the southern coast of the Kola Peninsula. New seismic-stratigraphic data were obtained on Quaternary deposits of the transition zone from the deep-water part of Kandalaksha Bay to its narrow shallow part. A combined (land-sea) geomorphological scheme and map of the last glaciation for the Solovetsky Islands were compiled; based on the study of several key areas, a paleogeographic scheme of evolution from glacial-lacustrine to glacial-marine-deep-sea and shallow marine and coastal aeolian deposits was created. For Quaternary deposits in the south of the Kola Peninsula, wells were drilled, including up to the crystalline basement.
