Middle Weichselian environments on western Yamal Peninsula, Kara Sea based on pollen records
Pollen data from two sections from coastal cliff on western Yamal Peninsula (69°43.27ŽN, 66°48.80ŽE) document the environmental history during the Karginsky (Middle Weichselian) interstadial. Low pollen concentrations, large amounts of redeposited pollen, and relatively large presence of Artemisia p...

Low pollen concentrations, large amounts of redeposited pollen, and relatively large presence of Artemisia pollen characterize sediments deposited c. 33 14C ka. The narrow 14C age interval possibly indicate that some of the plant macrofossils might be reworked and/or it may indicate high accumulation rate with deposition.
