Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]
, 2002 The relationship between the evolution of subglacial drainage system morphology and spatial patterns of glacier surface velocity was investigated using dye tracing experiments and ground surveying throughout the 1995 melt season at Haut Glacier d'Arolla,

Enthalpy balance theory unifies diverse glacier surge behaviour
Annals of Glaciology, 2022 It is commonly asserted that there are two distinct classes of glacier surges: slow, long-duration ‘Svalbard-type’ surges, triggered by a transition from cold- to warm-based conditions (thermal switching), and fast, shorter-duration ‘Alaska-type’ surges ...

Implications of climate change on Glacier de la Plaine Morte, Switzerland [PDF]
Geographica Helvetica, 2013 Changes in Switzerland's climate are expected to have major impacts on glaciers, the hydrological regime and the natural hazard potential in mountainous regions.

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

Marine outlet glacier dynamics, steady states and steady-state stability
Journal of Glaciology, 2022 Laterally confined marine outlet glaciers exhibit a diverse range of behaviours. This study investigates time-evolving and steady configurations of such glaciers.

Sustained retreat of the Pine Island Glacier [PDF]
, 2013 We use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and shoaling of the glacier surface and bedrock slopes, respectively, which ...

Journal of Glaciology, 2023 The Tian Shan mountain range, known as the water towers of Central Asia, plays a key role in local water supply, yet large uncertainties remain about the amount of water that is stored in its glaciers.

Ice‐Dynamical Glacier Evolution Modeling—A Review
Reviews of Geophysics, 2022 AbstractGlaciers play a crucial role in the Earth System: they are important water suppliers to lower‐lying areas during hot and dry periods, and they are major contributors to the observed present‐day sea‐level rise. Glaciers can also act as a source of natural hazards and have a major touristic value.

Sub-debris melt rates on southern Inylchek Glacier, central Tian Shan [PDF]
, 2008 Melt rates of glacier surfaces are strongly influenced by the existence of a debris cover. Dependent on thickness and other physical parameters the debris layer can enhance or reduce ablation as compared to bare ice conditions.

A Model of a Surging Glacier [PDF]
Journal of Glaciology, 1972 Abstract As the cause of a surge we assume a sudden improvement of the sliding conditions at the glacier bed. This improvement has the same effect on the behaviour of the glacier as an equivalent variation of the annual balance. We are therefore able to apply Nye’s (1963) theory of the advance and retreat of glaciers to our problem. A
