- Sediment successions in coastal cliffs around Mezen Bay, southeastern White Sea, record an unusually detailed history of former glaciations, interstadial marine and fluvial events from the Weichselian. A regional glaciation model for the Weichselian is based on new data from the Mezen Bay area and previously published data from adjacent areas. Following the Mikulinian (Eemian) interglacial a shelf-centred glaciation in the Kara Sea is reflected in proglacial conditions at 100-90 ka. A local ice-cap over the Timan ridge existed between 75 and 65 ka. Renewed glaciation in the Kara Sea spread southwestwards around 60 ka only, interrupted by a marine inundation, before it advanced to its maximum position at about 55-50 ka. After a prolonged ice-free period, the Scandinavian ice-sheet invaded the area from the west and terminated east of Mezen Bay about 17 ka. The previously published evidence of a large ice-dammed lake in the central Arkhangelsk region, Lake Komi, finds no support in this study. Copyright (C) 2003 John Wiley Sons, Ltd.
