Holocene ice wedges of the Kolyma Lowland and January paleotemperature reconstructions based on oxygen isotope records
Abstract Ice wedges in the Holocene deposits of alases and floodplains have been studied in the Kolyma Lowland region. Most ice wedges have been found within alases dated to between 11 and 4.2 cal kyr BP, corresponding to the Greenlandian and Northgrippian stages of the Holocene. This study confirms...
