The polygenetic hypothesis of Yedoma origin – comparing grain-size distributions of Alaskan and Siberian Yedoma [PDF]

open access: yes, 2016
The formation of late Pleistocene Yedoma in western Beringia (Siberia) is still widely debated. Moreover, different geological and cryostratigraphical views on Yedoma exist between researchers focusing on western or eastern Beringia (Alaska and Northwest

Utilization of ancient permafrost carbon in headwaters of Arctic fluvial networks [PDF]

open access: yes, 2015
Northern high-latitude rivers are major conduits of carbon from land to coastal seas and the Arctic Ocean. Arctic warming is promoting terrestrial permafrost thaw and shifting hydrologic flowpaths, leading to fluvial mobilization of ancient carbon stores.

Seasonal Impact on 3D GPR Performance for Surveying Yedoma Ice Complex Deposits

open access: yesFrontiers in Earth Science, 2022
Ground-penetrating radar (GPR) is a popular geophysical method for imaging subsurface structures with a resolution at decimeter scale, which is based on the emission, propagation, and reflection of electromagnetic waves.

Microbial and Geochemical Evidence of Permafrost Formation at Mamontova Gora and Syrdakh, Central Yakutia

open access: yesFrontiers in Earth Science, 2021
Biotracers marking the geologic history and permafrost evolution in Central Yakutia, including Yedoma Ice Complex (IC) deposits, were identified in a multiproxy analysis of water chemistry, isotopic signatures, and microbial datasets.

Organic matter characteristics in yedoma and thermokarst deposits on Baldwin Peninsula, west Alaska [PDF]

open access: yesBiogeosciences, 2018
As Arctic warming continues and permafrost thaws, more soil and sedimentary organic matter (OM) will be decomposed in northern high latitudes. Still, uncertainties remain in the quality of the OM and the size of the organic carbon (OC) pools stored in

Implications of yedoma bank outcrops on the arctic rivers sediment runoff

open access: yesГидросфера. Опасные процессы и явления, 2023
Размыв обнажений многолетнемерзлых пород (едома) в бортах долин крупных рек Арктики рассматривается как важный источник поступления взвешенных наносов и углерода в природные воды рек Лена, Колыма, Яна, Индигирка и далее в Северный ледовитый океан.

DataSheet1_Circum-Arctic Map of the Yedoma Permafrost Domain.pdf

open access: yes, 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.

Distribution of mineral constituents in Yedoma permafrost: implications for Yedoma formation [PDF]

open access: yes, 2018
Ice-rich permafrost deposits such as Yedoma are highly sensitive to thaw and given that they contain up to one third of the organic carbon content of the Northern circumpolar permafrost region, their degradation is considered to be a potential climate ...

Sub-Surface Carbon Stocks in Northern Taiga Landscapes Exposed in the Batagay Megaslump, Yana Upland, Yakutia

open access: yesLand, 2020
The most massive and fast-eroding thaw slump of the Northern Hemisphere located in the Yana Uplands of Northern Yakutia was investigated to assess in detail the cryogenic inventory and carbon pools of two distinctive Ice Complex stratigraphic units and ...
