Abstract

 Geomorphological, ground penetration radar profiling and paleolimnological investigations were carried out in the Kobyl`e (11 m asl), Chevakino (7 m asl), and Lopshen`gskoye (1 m asl) Lakes. Based on the lithology data, we obtain the relative sea-level (RSL) changes in the northern part of Gulf of Dvina (White Sea, Arctic Ocean) during the Holocene. The levels of two transgressions (Late Glacial and Tapes) and one Early Holocene regression are identified. According to the lithology composition of bottom sediments, investigated lakes has a longer transitional stage, then lakes in 22 km to the south.
