Ice wedges are a characteristic feature of northern permafrost landscapes and grow mainly
by snowmelt that refreezes in thermal contraction cracks that open in winter. In high latitudes …

Abstract Late Pleistocene and Holocene ground ice are common throughout the Arctic.
Some forms of relict ground ice preserve local meteoric water, and their stable oxygen‐and …

Ice-rich Pleistocene-age permafrost is particularly vulnerable to rapid thaw, which may
quickly expose a large pool of sedimentary organic matter (OM) to microbial degradation …

The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to
increased microbial decomposition in a warming climate. The environmental parameters …

Dating of ancient permafrost is essential for understanding long-term permafrost stability and
interpreting palaeoenvironmental conditions but presents substantial challenges to …

A megaslump at Batagaika, in northern Yakutia, exposes a remarkable stratigraphic
sequence of permafrost deposits~ 50–80 m thick. To determine their potential for answering …

Syngenetic permafrost deposits formed extensively on and around the arising Beringian
subcontinent during the Late Pleistocene sea level lowstands. Syngenetic deposition …

Palaeoenvironmental reconstructions with temporal coverages extending beyond Marine
Isotope Stage (MIS) three are scarce within the data sparse region of Chukotka, Far East …

Central Yakutia is a large region in northeastern Siberia characterized by extensive
permafrost, large river valleys, mountain glaciers, and large massifs of aeolian sands; the …

Paleoenvironmental and paleoclimatic changes at the transition from the Late Pleistocene to
the Early Holocene in the arctic Western Beringia (AWB) appear to be extremely important …
