Permafrost Landscapes: Classification and Mapping [PDF]
Geosciences, 2019 Permafrost landscapes occupy 25% of the world’s land area. The formation, dynamics, and evolution of these landscapes are greatly controlled by permafrost processes and thus require special approaches to classification and mapping. Alases, pingoes,

Frontiers in Environmental Science, 2022 Soil carbon (C) in permafrost peatlands is vulnerable to decomposition with thaw under a warming climate. The amount and form of C loss likely depends on the site hydrology following permafrost thaw, but antecedent conditions during peat accumulation are

Evidence for unexpected net permafrost aggradation driven by local hydrology and climatic triggers
Environmental Research Letters, 2023 Rapid rates of high latitude warming over the past century have led to widespread research on permafrost thaw and its consequences. Studies from lowland plains environments in the discontinuous permafrost zone have highlighted extensive areal loss of ...

Ice Volumes in Permafrost Landscapes of Arctic Yakutia
Land, 2022 This article is devoted to the study of the distribution of ground ice volumes in the upper layers of 5–10 m permafrost in the permafrost landscapes of Arctic Yakutia. Compilation of such a map will serve as a basis for assessing the vulnerability of permafrost to global warming, anthropogenic impact and forecasting the evolution of permafrost ...

Past permafrost dynamics can inform future permafrost carbon-climate feedbacks
Communications Earth & Environment, 2023 Climate warming threatens to destabilize vast northern permafrost areas, potentially releasing large quantities of organic carbon that could further disrupt the climate.

Landsat-Based Monitoring of Landscape Dynamics in Arctic Permafrost Region
Journal of Remote Sensing, 2022 Ice-rich permafrost thaws as a result of Arctic warming, and the land surface collapses to form characteristic thermokarst landscapes. Thermokarst landscapes can bring instability to the permafrost layer, affecting regional geomorphology, hydrology, and ...

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