Reconstructing Permafrost Sedimentological Characteristics and Post-depositional Processes of the Yedoma Stratotype Duvanny Yar, Siberia

Frontiers in Earth Science, 2021
Cryogenic weathering is a key driver of periglacial sediment composition and properties. Selective mineral-grain weathering caused by freeze-thaw cycles in permafrost environments has the ability to dominate this process, leading to silt-rich grain-size ...

Deglacial Permafrost Organic Carbon Delivery at the Northern Svalbard Continental Margin: Insights From Tetraether Lipids and Plant Biomarkers

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 6, June 2026.
Abstract Degradation of Arctic permafrost due to global warming and sea level rise could trigger positive feedbacks, exacerbating climate change. However, uncertainties remain on how permafrost systems may respond because we lack a complete understanding of the permafrost‐climate feedback.

Reconciling carbon-stock estimates for the Yedoma region [PDF]

, 2016
Permafrost soil organic carbon (C) in the Yedoma region comprises a large fraction of the total circumpolar permafrost C pool, yet estimates based on different approaches during the past decade have led to disagreement in the size and composition of the ...

Erosional and Hydrological Controls on the Age and Thermochemical Stability of Particulate Organic Carbon in an Arctic River

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Understanding the mechanisms that drive the mobilization and fate of organic carbon (OC) in Arctic landscapes is important for modeling the feedbacks among permafrost thaw, carbon cycling, and climate change. While significant progress has been made toward measuring in situ OC decomposition in permafrost soils and bulk particulate organic ...

Gas Permeability of Frozen Sediments: Implications for Modeling Gas and Water Transport in Permafrost

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract We measure the gas permeability of two permafrost sediments at a range of ice saturations and use van Genuchten‐Mualem equations to model the relative gas (krg) and water (krw) permeabilities of frozen sediments. We show that our frozen sediment krg data and model display the same functional form as frozen and unfrozen sediment krg data from ...

Variable respiration rates of incubated permafrost soil extracts from the Kolyma River lowlands, north-east Siberia

Polar Research, 2017
Thawing permafrost supplies dissolved organic carbon (DOC) to aquatic systems; however, the magnitude, variability and fate of this DOC is not well constrained. Our objective was to examine DOC respiration from seasonally thawed and near-surface (

Modelling the Sensitivity of Yukon River Biogeochemical Dynamics to Environmental and Chemical Drivers: Implications for Dissolved Organic Carbon

Hydrological Processes, Volume 40, Issue 4, April 2026.
We present a novel, process‐based, river model that effectively captures the interplay among hydrological, chemical, and soil parameters shaping riverine DOC transformations and reproduces observed DOC concentrations in the Yukon River. Sensitivity analysis highlights the importance of understanding the variability in DOC entering the headwater from ...
