Facies analysis of yedoma thermokarst lakes on the northern Seward Peninsula, Alaska [PDF]

, 2016
Thermokarst lakes develop as a result of the thaw and collapse of ice-rich, permanently frozen ground (permafrost). Of particular sedimentological importance are thermokarst lakes forming in late Pleistocene icy silt (yedoma), which dramatically alter ...

Thermokarst Lagoons - Carbon Pools and Panarctic Distribution

, 2020
The permafrost carbon (C) pool is a major storage component of the terrestrial C cycle and it is vulnerable in a warming climate. Permafrost carbon is mobilized by different processes of thaw and erosion, including thermokarst and thermo-erosion.

The future of community- and policy- relevant thermokarst research: Lessons learned and a call to action

, 2021
Several decades of research have provided insight into patterns of and controls on thermokarst initiation and expansion, yet studies tend to focus on individual types of thermokarst (i.e., thaw lake formation and subsequent drainage) in particular ...

The evolution of a thermokarst-lake landscape: late Quaternary permafrost degradation and stabilization in interior Alaska

, 2016
Thermokarst processes characterize a variety of ice-rich permafrost terrains and often lead to lake formation. The long-term evolution of thermokarst landscapes and the stability and longevity of lakes depend upon climate, vegetation and ground ...

Organic Carbon and Nitrogen Stocks along a Thermokarst Lake Sequence in Arctic Alaska

, 2019
Thermokarst lake landscapes are permafrost regions, which are prone to rapid (on seasonal to decadal timescales) changes, affecting carbon and nitrogen cycles.

Evaluation of the energy budget of thermokarst lake in permafrost regions of the Qinghai–Tibet Plateau

Advances in Climate Change Research
Thermokarst lake formation accelerates permafrost degradation due to climate warming, thereby releasing significant amounts of carbon into the atmosphere, complicating hydrological cycles, and causing environmental damage.

Conceptualization and Application of the Alaska Thermokarst Model [PDF]

, 2016
Thermokarst topography forms whenever ice-rich permafrost thaws and the ground subsides due to the volume loss when ground ice transitions to water. The Alaska Thermokarst Model (ATM) is a large- scale, state-and-transition model designed to simulate ...

Application of remote sensing and mathematical morphology of landscape for studying thermokarst processes [PDF]

, 2012
The purpose of this work is to study the development and regularity of morphological structures associated with thermokarst processes. An attempt is made to solve two problems, by analyzing the spatial regularity of morphological structures associated ...

Characterization of organic matter stored in Yedoma and thermokarst permafrost

, 2016
The permafrost region approximately makes up one quarter of the land surface of the Northern Hemisphere. Its soil organic carbon pool is estimated to be about twice the size of carbon in the modern atmosphere.
