Unstable early-Holocene climatic and environmental conditions in northwestern Russia derived from a multidisciplinary study of a lake-sediment sequence from Pichozero, southeastern Russian Karelia
A sediment core from Lake Pichozero (61degrees46'; N, 37degrees25'; E 118 m a.s.l.) provides information on the environmental and climatic conditions in southeastern Russian Karelia during the Lateglacial and early Holocene (12800-9300 cal. BP). The chronology of the sequence is constraine...

A sediment core from Lake Pichozero (61degrees46'; N, 37degrees25'; E 118 m a.s.l.) provides information on the environmental and climatic conditions in southeastern Russian Karelia during the Lateglacial and early Holocene (12800-9300 cal.
