Excess Ground Ice Profiles in Continuous Permafrost Mapped From InSAR Subsidence

Water Resources Research
Excess ground ice formation and melt drive surface heave and settlement, and are critical components of the water balance in Arctic soils. Despite the importance of excess ice for the geomorphology, hydrology and biogeochemistry of permafrost landscapes,

Hydrochemistry of hillslope permafrost catchments with degrading and stable ice-wedge polygons, Ogilvie Mountains, Yukon, Canada

Arctic Science
Ice-wedge polygonal terrain is one of the most widespread landscapes in continuous permafrost, and at many locations, is undergoing substantial degradation.

On the potential of hand-held GPS tracking of fjord ice features for remote-sensing validation

Annals of Glaciology, 2018
Research on young thin sea ice is essential to understand the changes in the Arctic. But it is also the most challenging to investigate, both in situ and from satellites.

The role of hydrothermal processes in permafrost degradation on China’s Qilian Eboling Ridge

Geoderma
Warming climate has led to permafrost degradation at varying rates, which can accelerate the release of permafrost carbon and ground ice melt. However, these impacts are not clear and the sensitivity of ice and peat-rich permafrost to climate change has ...

Spatial distribution and zonation characteristics of permafrost ground ice on the Qinghai‒Xizang Engineering Corridor, China

Advances in Climate Change Research
Permafrost ground ice represents a critical solid water resource and engineering medium, with high ice-content permafrost in the Qinghai‒Xizang Engineering Corridor (QTEC) exhibiting heightened sensitivity to degradation, which in turn limiting our ...

Stock Frost or Ground Ice [PDF]

Nature, 1908
DURING the recent frosty weather the subject of what is locally called “stock frost” has been much to the front in this neighbourhood. This phenomenon is known to the scientific world, I believe, as “ground ice,” and the circumstances in which it appears and disappears present to the ordinary observer a very great many puzzling features.

Reassessing Alpine Permafrost Thermal State by Accounting for Ground Ice

Earth's Future
Permafrost thermal state, representing the stored “cold energy” in the ground, is crucial for assessing permafrost changes. However, the conventional metric, mean annual ground temperature (MAGT), has inherent limitations because it overlooks the ...

Distributed De-Icing Approach for Overhead Ground Wires Based on AC Power Supply with Thermodynamic Validation

Energies
The accumulation of ice on power lines severely affects the safety of power systems. Conventional ice melting methods suffer from poor flexibility and adaptability, accompanied by high power consumption.

Thermo-hydro-mechanical analysis of subsurface ice-based thermal energy storage

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
Ice-based thermal energy storage systems are widely utilized for cooling and managing peak electrical demand globally, offering daily or weekly storage capabilities for both individual homes and larger office buildings. However, scaling these systems for
