Structure and formation of ice-ground veins of the second lake-alluvial terrace in the North of Gydan in the late Neopleistocene–Holocene

Лëд и снег, 2019
The syngenetic ice and ice-ground composite veins in khasyrey (alas) and interalas plateaus were studied on the second lake-alluvial terrace located in the North of the Gydan Peninsula near the village of Gyda. On the basis of the radiocarbon dating, the

Vertical distribution of excess ice in icy sediments and its statistical estimation from geotechnical data (Tuktoyaktuk Coastlands and Anderson Plain, Northwest Territories)

Arctic Science, 2023
Excess ice, found as massive ice and within icy sediments, is an important variable to quantify as it is a dominant control on the terrain and geotechnical response to permafrost thaw.

Doped colloidal artificial spin ice

New Journal of Physics, 2015
We examine square and kagome artificial spin ice for colloids confined in arrays of double-well traps. Unlike magnetic artificial spin ices, colloidal and vortex artificial spin ice realizations allow creation of doping sites through double occupation of

A Comparison of Frequency Domain Electro-Magnetometry, Electrical Resistivity Tomography and Borehole Temperatures to Assess the Presence of Ice in a Rock Glacier

Frontiers in Earth Science, 2020
Alpine permafrost is currently warming, leading to changes such as active layer deepening and talik formation. Frequency domain electro-magnetometry (FDEM) measurements were tested as a simple and efficient method to investigate ground characteristics ...

Ice–shelf Grounding: Ice and Bedrock Temperature Changes [PDF]

Journal of Glaciology, 1980
AbstractIce rises form where an ice shelf runs aground on the sea bed. After grounding occurs, basal ice temperatures cool from the sea-water temperature towards an equilibrium temperature appropriate to grounded ice. This cooling can take many thousands of years, and much of the delay is due to the thermal inertia of the bedrock.

Vertical Structure of a Snowfall Event Based on Observations From the Aircraft and Mountain Station in Beijing

Frontiers in Environmental Science, 2021
An aircraft platform, ground-based disdrometer, cloud radar, radiometer, and automatic station were combined to study a snowfall case (16:30–21:00 observed by ground cloud radar) on the Yangqing Mountains in Beijing.

Projecting circum-Arctic excess-ground-ice melt with a sub-grid representation in the Community Land Model

The Cryosphere, 2019
. To address the long-standing underrepresentation of the influences of highly variable ground ice content on the trajectory of permafrost conditions simulated in Earth system models under a warming climate, we implement a sub-grid representation of ...

Mathematical Model for Determination of EMF and Current Induced in the Loop of Lighting Protection Cable by Magnetic Fields of 220 KV Phase Currents

Российская Арктика, 2022
The electrical grid of regional power systems primarily uses double-circuit 220 kV overhead power lines to function. This paper provides information on the problem of ice formation on overhead ground wires of 220 kV power lines, including a brief ...

Microtopographic control on the ground thermal regime in ice wedge polygons [PDF]

The Cryosphere, 2018
The goal of this research is to constrain the influence of ice wedge polygon microtopography on near-surface ground temperatures. Ice wedge polygon microtopography is prone to rapid deformation in a changing climate, and cracking in the ice wedge ...
