Rock waste dumps on the Davydov Glacier (Akshyirak Range, Tien Shan)

Лëд и снег, 2015
Since 1995, a barren rock has been formed at the Davydov Glacier, due to the works at the Kumtor Gold Mine. By the end of 2010, total amount of the rock, stockpiled on the glacier, apparently exceeded 200 million tons, the height of dumps of rock ...

Recent and future variability of the ice-sheet catchment of Sermeq Kujalleq (Jakobshavn Isbræ), Greenland

Journal of Glaciology
Knowledge of ice-sheet catchments is critical for mass-balance assessments, especially glacier-scale input–output budgets. This study explores variations in the catchment of Sermeq Kujalleq, or Jakobshavn Isbrø, Greenland. Six observation-based catchment

Glacier Algae: A Dark Past and a Darker Future

Frontiers in Microbiology, 2019
“Glacier algae” grow on melting glacier and ice sheet surfaces across the cryosphere, causing the ice to absorb more solar energy and consequently melt faster, while also turning over carbon and nutrients.

Mass balance of glacier No. 139 in the basin of Lake Karakul in the Eastern Pamirs

Central Asian Journal of Water Research, 2022
Mountain glaciers, including the poorly examined glaciers of Lake Karakul Basin, are considered the most vulnerable part of the cryosphere directly reacting to the changing climatic conditions.

Was Scotland deglaciated during the Younger Dryas? [PDF]

, 2016
Recent work has produced data that challenges the canonical view that the Younger Dryas (c.12.9–11.7 ka) was a time of glacier expansion across the North Atlantic. Boulders on moraines located within the inner sector of the Scottish Loch Lomond Stadial (≈

Global glaciological models: a new stage in the development of methods for predicting glacier evolution. Part 1. General approach and model architecture

Лëд и снег, 2021
For several decades, mathematical models of mountain glaciers and ice sheets have been used to study the dynamics of the cryosphere. In recent years, a new step in glaciological modeling has made possible to recon- struct processes in mountain-glacial ...

Soil Microbial Networks Shift Across a High-Elevation Successional Gradient. [PDF]

, 2019
While it is well established that microbial composition and diversity shift along environmental gradients, how interactions among microbes change is poorly understood.

Numerical simulation of glacier terminus evolution using the dual action principle for momentum balance

Journal of Glaciology
The momentum conservation equation for glacier flow can be described through minimization of an action functional. Several software packages for glacier flow modeling use this action principle in the design of numerical solution procedures.

Landslide-generated tsunami and particle transport in mountain lakes and reservoirs

Annals of Glaciology, 2016
Gravitational mass flows may generate tsunamis as they hit water bodies such as oceans, reservoirs or mountain lakes. Upon impact, they can generate tremendous particle-laden or debris flows and floods.
