Circum-Arctic Map of the Yedoma Permafrost Domain [PDF]

Frontiers in Earth Science, 2021
Ice-rich permafrost in the circum-Arctic and sub-Arctic (hereafter pan-Arctic), such as late Pleistocene Yedoma, are especially prone to degradation due to climate change or human activity.

Iron Redistribution Upon Thermokarst Processes in the Yedoma Domain [PDF]

Frontiers in Earth Science, 2021
Ice-rich permafrost has been subject to abrupt thaw and thermokarst formation in the past and is vulnerable to current global warming. The ice-rich permafrost domain includes Yedoma sediments that have never thawed since deposition during the late ...

Implications of Yedoma bank outcrop on the Arctic river sediment transport

Scientific Reports
Our study records the interaction of hydrological and periglacial processes caused by the syngenetic permafrost (yedoma) transformation on the largest Siberian River.

Yedoma Permafrost Genesis: Over 150 Years of Mystery and Controversy

Frontiers in Earth Science, 2022
Since the discovery of frozen megafauna carcasses in Northern Siberia and Alaska in the early 1800s, the Yedoma phenomenon has attracted many Arctic explorers and scientists.

Geomorphological and Climatic Drivers of Thermokarst Lake Area Increase Trend (1999–2018) in the Kolyma Lowland Yedoma Region, North-Eastern Siberia

Remote Sensing, 2021
Thermokarst lakes are widespread in Arctic lowlands. Under a warming climate, landscapes with highly ice-rich Yedoma Ice Complex (IC) deposits are particularly vulnerable, and thermokarst lake area dynamics serve as an indicator for their response to ...

A globally relevant stock of soil nitrogen in the Yedoma permafrost domain [PDF]

Nature Communications, 2022
A climate sensitive permafrost region (Yedoma domain) was found to contain globally relevant N stock of >40 Gt nitrogen, of which 4 to 16 Gt of the N could become available by thaw until 2100. This study increases the current estimates by nearly 50%.

Paleo-Ecology of the Yedoma Ice Complex on Sobo-Sise Island (EasternLena Delta, Siberian Arctic)

Frontiers in Earth Science, 2021
Late Pleistocene permafrost of the Yedoma type constitutes a valuable paleo-environmental archive due to the presence of numerous and well-preserved floral and faunal fossils.

Upland Yedoma taliks are an unpredicted source of atmospheric methane

Nature Communications
Landscape drying associated with permafrost thaw is expected to enhance microbial methane oxidation in arctic soils. Here we show that ice-rich, Yedoma permafrost deposits, comprising a disproportionately large fraction of pan-arctic soil carbon, present

Simulating soil organic carbon in yedoma deposits during the Last Glacial Maximum in a land surface model

Geophysical Research Letters, 2016
Substantial quantities of organic carbon (OC) are stored in the thick, ice‐rich, and organic‐rich sediments called yedoma deposits, distributed in eastern Siberia and Alaska today.

Validity of radiocarbon ages of Siberian yedoma

GeoResJ, 2017
Abstract The ice wedges are considered as key subjects for 14C aging of yedoma, as there are no any exchange processes between the environment and the ice wedges. Syngenetic sediments contain allochthonous organic admixtures which originated at a distance from its present position.
