Permafrost and Periglacial Processes, EarlyView.ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

Evidence for nonuniform permafrost degradation after fire in boreal landscapes [PDF]
Journal of Geophysical Research: Earth Surface, 2016 AbstractFire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire‐induced change.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT The amount and stratigraphic setting of ground ice in permafrost slopes is a key control on the style and magnitude of permafrost mass wasting. Understanding the spatial and stratigraphic variations in ground ice distribution on permafrost slopes is therefore a fundamental property in assessing the stability of permafrost hillslopes.

Estimation of Excess Ice and Thaw Settlement in Frozen Soil Using Industrial Computed Tomography
Permafrost and Periglacial Processes, EarlyView.ABSTRACT Permafrost thaw can induce terrain instabilities and hazards as a result of the loss of excess ice from host sediments. The loss of excess ice threatens the integrity of infrastructure and drives ecosystem changes across northern landscapes. This study tests a nondestructive approach to estimate excess ice and potential thaw settlement using ...

Microbial nutrient limitation in Arctic lakes in a permafrost landscape of southwest Greenland
, 2015 . Permafrost is degrading across regions of the Arctic, which can lead to increases in nutrient concentrations in surface freshwaters. The oligotrophic state of many Arctic lakes suggests that enhanced nutrient inputs may have important effects on these ...

Marshy pools on permafrost mitigate landscape‐scale climate warming [PDF]
Eos, Transactions American Geophysical Union, 2014 Starting 5000 years ago, small marshy lakes dotting northern Siberia became significant carbon sinks, cooling the climate on a landscape scale. Researchers from the University of Alaska Fairbanks (UAF) published their findings in Nature online on 16 July.

Permafrost and Periglacial Processes, EarlyView.ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...
