Winter air temperature during the Holocene optimum in the north‐eastern part of the east European plain based on ice wedge stable isotope records
Abstract Early Holocene winter air temperatures have been reconstructed for the north‐eastern part of the East European Plain using stable isotope (δ 18 O and δ 2 H) records of syngenetic ice wedges. We show that ice wedges here actively grew synchronously with accumulation of peatlands in bogged an...

Abstract Early Holocene winter air temperatures have been reconstructed for the north‐eastern part of the East European Plain using stable isotope (δ 18 O and δ 2 H) records of syngenetic ice wedges.
