Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal [PDF]

open access: yes, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

Assessment of glacier lakes development potential in the Central Caucasus

open access: yesЛëд и снег, 2020
Glacier mass loss and consequent terminus retreat lead to formation and growth of glacier lakes. In Caucasus outbursts of glacial lakes formed in recent decades have led to human casualties and significant damage. In this study the location and volume of

Intra-annual and intra-seasonal flow dynamics of a High Arctic polythermal valley glacier [PDF]

open access: yes, 2002
Measurements of surface dynamics on polythermal John Evans Glacier, Nunavut, Canada, over two winter periods and every 7-10 days throughout two melt seasons (June-July 2000, 2001) provide new insight into spatio-temporal patterns of High Arctic glacier ...

Experiments with model glaciers

open access: yesGeographical Review of Japan, 1926
A piece of apparatus was designed with which it was hoped to determine the relative rates at which glacier ice would respond by flow to the same head at varying depth pressures. The primary object of the experiments was frustrated, but measurements were secured which permitted the plotting of a curve showing the approximate relation of rate of flow and

Monte Carlo ice flow modeling projects a new stable configuration for Columbia Glacier, Alaska, c. 2020 [PDF]

open access: yesThe Cryosphere, 2012
Due to the abundance of observational datasets collected since the onset of its retreat (c. 1983), Columbia Glacier, Alaska, provides an exciting modeling target.

A framework for three-dimensional dynamic modeling of mountain glaciers in the Community Ice Sheet Model (CISM v2.2) [PDF]

open access: yesGeoscientific Model Development
It is essential to improve our understanding of glaciers and their effects on sea levels, ecosystems, and freshwater resources in a changing climate. To this end, we implemented a framework for three-dimensional, high-resolution, regional-scale glacier ...

A minimal model of a tidewater glacier [PDF]

open access: yesAnnals of Glaciology, 2005
AbstractWe propose a simple, highly parameterized model of a tidewater glacier. The mean ice thickness and the ice thickness at the glacier front are parameterized in terms of glacier length and, when the glacier is calving, water depth. We use a linear relation between calving rate and water depth.

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]

open access: yes, 2011
The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

AGILE v0.1: The Open Global Glacier Data Assimilation Framework [PDF]

open access: yesGeoscientific Model Development
The growing availability of glacier observations poses a challenge for models to integrate this heterogeneous information in a dynamically consistent way.

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

open access: yes, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,
