Thinning-induced glacier deceleration in the Zanskar Himalayas [PDF]
The CryosphereTrends in surface velocity provide insight into glacier response to climate change as well as local drivers of ice dynamics. The Zanskar Himalayas are heavily glacierised, and retreating glaciers pose a threat to local and regional water security ...

Creep-Velocity Bounds and Glacier-Flow Problems [PDF]
Journal of Glaciology, 1967 Abstract A general result due to Martin can be used to find upper and lower bounds on velocities in steady-creep problems. This method can be applied to glacier flow if ice can be assumed to satisfy a powerlaw stress–strain-rate relation.

Proximity to active volcanoes enhances glacier velocity
Communications Earth & EnvironmentAbstractVolcanic heating is predicted by theory to affect the velocity of nearby glaciers. However, conclusive studies on a large scale are lacking. Here, we conduct a global comparison of the velocities of glaciers near active volcanoes (i.e. within 5 km) and those located elsewhere ( > 5 km from an active volcano).

The equilibrium flow and mass balance of the Taku Glacier, Alaska 1950–2006 [PDF]
The Cryosphere, 2008 The Taku Glacier, Alaska has advanced 7.5 km since the late nineteenth century, while all other primary outlet glaciers of the Juneau Icefield are in retreat.

Utilising seismic station internal GPS for tracking surging glacier sliding velocity
Journal of GlaciologyGlacier ice flux is a key indicator of mass balance; therefore, accurate monitoring of ice dynamics is essential. Satellite-based methods are widely used for glacier velocity measurements but are limited by satellite revisit frequency.

ITS_LIVE global glacier velocity data in near-real time
The CryosphereAbstract. Glaciers and ice sheets cover some 15 million square kilometers of the Earth's surface, shaping continental landscapes and modifying climate on a global scale. Recent decades of atmospheric and oceanic warming have induced rapid glacier loss worldwide that has caused sea level rise, flooding, changes to Earth's overall energy balance, and ...

Slowdown of glacier velocity emerging in the Zanskar Himalayas
Abstract. Trends in glacier surface velocity provide insight into the response of glaciers to climate change as well as local drivers of ice dynamics. The Zanskar Himalayas are heavily glacierised, but retreating glaciers pose a threat to local and regional water security.
