Quantifying the Surface Deformation of Pingos on the Alaskan North Slope Using Interferometric Synthetic Aperture Radar (InSAR)

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 682-691, October/December 2026.
ABSTRACT Pingos are large mounds with cores formed of intrusive ice that form in periglacial landscapes. These ice structures can form in regions of discontinuous permafrost, commonly as hydraulic or open‐system pingos, or in locations of continuous permafrost, commonly as hydrostatic or closed‐system pingos.

Evolution of thermokarst in East Siberian ice-rich permafrost

, 2013
Thermokarst lakes and basins are major components of ice-rich permafrost landscapes in East Siberian coastal lowlands and are regarded as indicators of regional climatic changes.

Electrical Resistivity Tomography for the 2D and 3D Investigation of Pingos and Permafrost Mounds in Northern Canada's Mountain and Coastland Areas

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 804-829, October/December 2026.
ABSTRACT Pingos and related permafrost mounds are widespread periglacial landforms in Arctic environments that are ice‐rich on the one hand and contain taliks on the other, making them vulnerable to climate change. So far, the interior, geophysical characteristics, and distribution of ground ice within these dome‐ or cone‐shaped features have not been ...

Temporal Behavior of Lake Size-Distribution in a Thawing Permafrost Landscape in Northwestern Siberia

Remote Sensing, 2014
Arctic warming alters regional hydrological systems, as permafrost thaw increases active layer thickness and in turn alters the pathways of water flow through the landscape.

Frequency‐Domain Airborne Electromagnetic Imaging of Permafrost Reveals Heterogeneity and Drivers of Permafrost Change in the Discontinuous Permafrost Zone of Northwestern Canada

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract Northern permafrost landscapes are undergoing rapid warming and thaw, yet the three‐dimensional subsurface structure that governs thaw vulnerability and landscape response remains poorly resolved by conventional ground temperature monitoring and satellite remote sensing.

Organic carbon content in degrading permafrost beneath expanding thermokarst lakes

, 2014
Arctic lakes are globally significant sources of methane, resulting from anaerobic decomposition of thawed organic matter in lake bottoms. We examined patterns of permafrost degradation near thermokarst lakeshores in the tundra of Old Crow Flats, a 5600 ...

Biogeochemical and hydrochemical parameters of sediment core PG2412 beneath thermokarst lake Goltsovoye Lake on the Bykovsky Pensinula, northeastern Siberia

, 2020
These datasets describe a 31.5 m long sediment core taken from beneath thermokarst lake Goltsovoye Lake (71.74515 N, 129.30217 E) on the Bykovsky Peninsula, northeastern Siberia. The thermokarst lake was 510 cm deep.

Table1_From permafrost soil to thermokarst lake sediment: A view from C:N:P stoichiometry.XLSX

, 2022
Thermokarst lakes are formed as a result of thawing ice-rich permafrost, transforming vast permafrost soil into lake sediment and changing the biogeochemistry of carbon (C), nitrogen (N), and phosphorus (P).

Evaporation From Soil and Thermokarst Lakes Contribute More to Local Precipitation Than Plant Transpiration in Permafrost Regions of the Central Qinghai—Tibet Plateau

Water Resources Research
Permafrost degradation on the Qinghai—Tibet Plateau (QTP) directly affects evapotranspiration and moisture recycling processes by changing the underlying land surface conditions.

Rapid Increase in Geogenic CO2 Emissions from Antarctic Permafrost

Global Biogeochemical Cycles, Volume 40, Issue 10, October 2026.
Abstract Thawing permafrost can amplify climate change by releasing previously stored carbon, but observations of this feedback come mainly from the Arctic. Ice‐free Antarctic terrains are generally regarded as minor CO2 sources, although sub‐permafrost brines and deep carbon reservoirs may support localized geogenic degassing.
