Estimation of glacier ice extinction using long-wavelength airborne Pol-InSAR [PDF]

open access: yes, 2013
In recent years there has been increased interest in using synthetic aperture radar (SAR) to study and monitor glaciers and ice sheets for glaciological and climate change research.

Spatial differences of ice volume across High Mountain Asia

open access: yesAdvances in Climate Change Research, 2023
Advanced knowledge of glacier ice volume is vital for water resource assessment. Previous studies have focused on the estimation of ice volume, but the quantitative understanding of the spatial variability of ice volume across High Mountain regions is ...

A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics [PDF]

open access: yes, 2010
We present results from numerical ice-flow models that include calving criteria based on penetration of surface and basal crevasses, which in turn is a function of longitudinal strain rates near the glacier front.

Decadal evolution of a very small heavily debris-covered glacier in an Alpine permafrost environment

open access: yesJournal of Glaciology, 2016
Glacier response to climate forcing can be heterogeneous and complex, depending on glacier system characteristics. This article presents the decadal evolution of the Tsarmine Glacier (Swiss Alps), a very small and heavily debris-covered cirque glacier ...

Neural Networks Applied to Estimating Subglacial Topography and Glacier Volume [PDF]

open access: yesJournal of Climate, 2009
AbstractTo predict the rate and consequences of shrinkage of the earth’s mountain glaciers and ice caps, it is necessary to have improved regional-scale models of mountain glaciation and better knowledge of the subglacial topography upon which these models must operate.

Crevasses triggered on Pine Island Glacier by drilling through an exceptional melt layer [PDF]

open access: yes, 2010
The basic theory of crevasse formation suggests that crevasses initiate at or near the surface. However, due to variations in stress with depth, it has been suggested that it is possible for crevasses to initiate at depths of 10–30m.

Recent observations and glacier modeling point towards near-complete glacier loss in western Austria (Ötztal and Stubai mountain range) if 1.5 °C is not met [PDF]

open access: yesThe Cryosphere
Most glaciers in Austria are expected to disappear in the coming decades. The general trend to deglaciation is apparent from observations of past glacier change as well as projections of future glacier evolution in the region.

Changes of Marukh Glacier from 1945 to 2011

open access: yesЛëд и снег, 2015
Field studies have been carried out in summer 2011 at Marukh Glacier located in western part of the Northern Caucasus. The studies included ground-based radio-echo sounding measurements at a frequency of 20 MHz and glacier surface elevation survey using ...

What is the global glacier ice volume outside the ice sheets?

open access: yesJournal of Glaciology, 2023
A recent study (Millan and others, 2022a, Nature Geoscience 15(2), 124–129) claims that ice volume contained in all glaciers outside the ice sheets and its potential contribution to sea level is 20% less than previously estimated.

Improving estimation of glacier volume change: a GLIMS case study of Bering Glacier System, Alaska [PDF]

open access: yesThe Cryosphere, 2007
Abstract. The Global Land Ice Measurements from Space (GLIMS) project has developed tools and methods that can be employed by analysts to create accurate glacier outlines. To illustrate the importance of accurate glacier outlines and the effectiveness of GLIMS standards we conducted a case study on Bering Glacier System (BGS), Alaska.
