...O.V. Nechaev; K.N. Danilovskiy; I.V. Mikhaylov Abstract —This article presents a novel approach to addressing the challenges in permafrost monitoring through the integration of deep-learning techniques with conventional electromagnetic sounding methods. Our methodology comprises a forward finite...

...Presley Greer; Shuhab D. Khan; Edgar A. Bering Abstract The warming of Alaska’s permafrost has been leading to thawing within its discontinuous permafrost. This can cause ice wedges to melt, resulting in thermokarst formations such as sinkholes and landslides, which are causing damage to Alaskan...

...Jefferson Bustamante; Gabriel Fabien-Ouellet; Mathieu J. Duchesne; Amr Ibrahim ABSTRACT Marine seismic surveys can be used to map ice-bearing subsea permafrost on a large scale. However, current seismic processing technologies have limited capacity to image permafrost distribution at depth, mainly...

...D.E. Edemsky; V.E. Tumskoy; I.V. Prokopovich Abstract —Ground penetrating radar method which was applied to study distribution and occurrence of polygonal wedge ice along with other structural features in the near-surface layers of the permafrost section on the western coast of the Taymyr Peninsula...

...Margaret M. Darrow; Ronald P. Daanen; Meaghan C. Gould Abstract Frozen debris lobes (FDLs) are slow-moving landslides in permafrost. FDL-A, the largest monitored FDL in the Brooks Range of Alaska, has steadily progressed downslope toward the Dalton Highway, which is the only road to the oil and gas...

...Ehsan Vosoughi; Bernard Giroux; Mathieu J. Duchesne; J. Christian Dupuis ABSTRACT Permafrost is a multiphase porous media that can host matter in all three states (solid, liquid, and gas). The equilibrium between the states of matter within the pore space is largely driven by salinity, pressure...

... deliquescence and differential salt mobility and cation exchange. Although the cation exchange mechanism was shown to explain the chemistry of pore waters in permafrost cores from several meters depth, it has not been evaluated for near-surface groundwater and wetland features (water tracks) in which excess...

.... 9c ), so it is standard practice to collect till samples from ≥1 m depth to ensure that the C-horizon has been sampled. Considerations for soil development in permafrost terrain is described in a later section. The design of a till sampling survey is governed by the size of the area...

...Jefferson Bustamante; Gabriel Fabien-Ouellet; Mathieu J. Duchesne; Amr Ibrahim ABSTRACT Monitoring the change in permafrost conditions and distribution is crucial for forecasting global warming. As seismic velocities increase with ice content, marine seismic surveys can map the top of ice-bearing...

...A.A. Galanin; I.V. Klimova; I.I. Khristoforov; Q. Wu; Zh. Ze Abstract —The surface pattern of permafrost area in the Tibetan Plateau, with 15–20 m polygons, resembles the patterned ground of the Arctic periglacial loess plains in northeastern Eurasia and North America. However, unlike the Arctic...

...M.N. Nikitenko; V.N. Glinskikh; I.V. Mikhaylov; A.A. Fedoseev Abstract —The study is aimed at theoretical development and scientific substantiation of a high-resolution transient electromagnetic (TEM) geophysical technique for monitoring the state of permafrost. The electromagnetic monitoring...

... focus is made on the seismic behavior of areas where seismic risk zoning is problematic because of permafrost. The paper presents synthesis of previous and new data on ground responses to large earthquakes in specific territories of the Baikal–Mongolia region with complex cryological conditions...

... as kinematically active failure surfaces or cause the generation of new joints that enhance hydraulic conductivity and rock mass weakening ( Evans and Clague 1994 ; Ballantyne 2002 ; McColl 2012 ). In addition, climate warming and the correlated permafrost degradation promote rock weathering, reduce the rock...

..., in subarctic northwest North America. However, new zircon U-Pb dates for the tephra suggest that the tephra was deposited ca. 207 ka during MIS 7, with wide-ranging implications for chronologies of glaciation, paleoclimate, relict permafrost, and phylogeography. We analyzed ~1900 detrital glass shards from 28...
