Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

MULTI-SCALE LANDSCAPE MAPPING OF THE TYUMEN REGION AS A GEOINFORMATION BASE FOR ORGANIZATION OF LANDSCAPE PLANNING, ENVIRONMENTAL MANAGEMENT AND REGIONAL SUSTAINABLE DEVELOPMENT

InterCarto. InterGIS, 2016
Landscape analysis is considered with the following items: 1) a synthetic layer integral physiographic information about the natural environment; 2) an information basis for mapping and evaluation components of landscapes; 3) a basis for the assessment ...

Internal Permafrost Structure of Geomorphologically Distinct Palsas in Northern Sweden Revealed by Quasi‐3D ERT

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

InSAR-derived seasonal subsidence reflects spatial soil moisture patterns in Arctic lowland permafrost regions [PDF]

The Cryosphere
The identification of spatial soil moisture patterns is of high importance for various applications in high-latitude permafrost regions but challenging with common remote sensing approaches due to high landscape heterogeneity.

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

Permafrost and Periglacial Processes, EarlyView.
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.

Geoinformation modeling of permafrost landscapes of North-Eastern Siberia

, 2022
The landscape-indicative approach makes it possible to determine permafrost landscapes based on the identification of two physiognomic indicators-variables of relief and vegetation, as well as stratigraphic-genetic sediment complexes. For permafrost characteristics of landscapes, multilevel combinations of environmental variables (criteria) for ...

Periglacial Puzzles: Unravelling Environmental Controls on Alpine Solifluction Lobe Dimensions and Shape

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Freeze–thaw processes cause periglacial creep (otherwise known as solifluction) which forms solifluction lobes. These are lobate features characterized by a steep riser (front) and a smooth tread (body). Despite the widespread occurrence of these lobes, the controls on their morphometry remain poorly understood. Research into solifluction lobe
