Аннотация:The paper presents the lithological and chronometric data (15 new and 9 earlier published dates) obtained in2018–2020 on the Upper Pleistocene sections along the Terskiy and Zimniy Coasts of the White Sea. Focused onthe Lower Weichselian (MIS 5d-a) and lower Middle Weichselian (MIS 4) sediment successions, the marine andglacial events are discussed. Marine environment was reconstructed in the White Sea basin, and water exchangebetween Barents and White Seas via Gorlo Strait. In the presented sedimentary succession, the sandy units datedto 72–66 ka and 63.5–53.5 ka on the Terskiy Coast and to 61–52 ka on the Zimniy Coast were associated with theMezen marine transgression. Glacial event during MIS 4 is suggested in the north-easternmost shore of the WhiteSea, where the Barents Ice Sheet expanded from the Kara and Barents Seas shelf and reached the eastern coast ofthe Mezen Bay. The Terskiy Coast (southern Kola Peninsula) seems to be affected by local glacial sheet during theearly Middle Weichselian.
