The effect of “annealing” on the specific crushing energy of the layered frozen ice.

Лëд и снег
The paper demonstrates realization of an experimental method of shock destruction of ice in order to study its specific energy of destruction and strength under various annealing conditions. Ice was prepared by layer-by layer freezing of distilled water.

From the Stochastic Weather to a Putative Chaotic Earth System [PDF]

arXiv, 2022
In this brief report we discuss how continuous changes on the physical parameters that determine the weather conditions may lead to long term climate variability. This variability of the weather patterns are a response to continuous random short period weather excitations that are imprinted in the ocean-atmosphere-cryosphere-land system, the Earth ...

Oscillatory subglacial drainage in the absence of surface melt [PDF]

, 2014
The presence of strong diurnal cycling in basal water pressure records obtained during the melt season is well established for many glaciers. The behaviour of the drainage system outside the melt season is less well understood.

Climates of the Earth and Cryosphere Evolution [PDF]

Surveys in Geophysics, 2011
The interrelationship between the cryosphere and the climate is not always operating on Earth over a scale of billions or millions of years. Indeed, most of the time, the Earth is regulated at temperatures such that no ice sheet exists. Nevertheless, it is very fruitful to understand the conditions where and when ice sheets were triggered during the ...

De Geer moraine internal architecture based on sedimentological and geophysical investigations and implications for ice‐marginal reconstructions

Boreas, EarlyView.
De Geer moraines may act as valuable ice‐marginal indicators; however, to date, their variable mode of formation has presented challenges for this utility. Here, we present sedimentological and ground penetrating radar data of DGMs located in southwest Finland.

The main results of monitoring the power of the active layer at CALM sites of the Nadymsky object

Vestnik MGTU
Monitoring of the thickness of the active layer within the lake-marsh type of terrain in the northern taiga was carried out at three sites organized in 1997, 2013 and 2022.

The role of inland ice dynamics in controlling the variable maximum extent of the Laurentide Ice Sheet off southeastern Baffin Island

Boreas, EarlyView.
Reconstructions of the maximum extent of the Laurentide Ice Sheet (LIS) and its associated ice flows at the Last Glacial Maximum (LGM) are needed for understanding how marine‐based ice sheets will respond to modern climate change. Here, we provide evidence for the location of the maximal extent of the LIS margin during the LGM in Merchants and ...

GIS and field data-based modelling of snow water equivalent in shrub tundra

Fennia: International Journal of Geography, 2015
An approach for snow water equivalent (SWE) modelling in tundra environments has been developed for the test area on the Yamal peninsula. Detailed mapping of snow cover is very important for tundra areas under continuous permafrost conditions, because ...

Mountain Cryosphere Landscapes in South America: Value and Protection

Conservation, 2023
Mountain landscapes support hydric and biodiversity potential under different ownership and land use perspectives. A focal point justifying their preservation is often the legislation’s ethical endorsement. Yet, when scales for assessment diverge without
