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

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

Spatial differences of ice volume across High Mountain Asia
Advances 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 ...

Including debris cover effects in a distributed model of glacier ablation [PDF]
, 2012 Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

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]
The CryosphereMost 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.

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

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

Changes of Marukh Glacier from 1945 to 2011
Лëд 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?
Journal 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.

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]
, 2016 Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.
