Velocity Changes of Rock Glaciers and Induced Hazards

2014
Recent observations and geodetic measurements in the European Alps show that changes are occurring on rock glacier dynamics, ranging from moderate velocity variations to strong acceleration or even total collapse. These changes can be related to the ground temperature and to climate warming.

Glacier Velocity Estimation by Means of a Polarimetric Similarity Measure

IEEE Transactions on Geoscience and Remote Sensing, 2013
The contribution of polarimetric synthetic aperture radar (PolSAR) images compared with that of single-channel SAR images in terms of temporal scene characterization has been found and described to add valuable information in the literature. However, despite a number of recent studies focusing on single-polarized glacier monitoring, the potential of ...

The distribution of stress and velocity in glaciers and ice-sheets

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1957
Abstract A block of ice resting upon a rough slope forms a theoretical model of a glacier or an ice-sheet, the sides of the glacier valley being ignored. Previous papers have described two types of steady flow in this model: (a) laminar flow, in which the longitudinal velocity gradient r is zero, and (b) extending or compressive flow,

Seismic Wave Velocities in the Hans Glacier, Spitsbergen

2013
Direct measurements of P and S wave velocities were performed by a special seismometer array on the Hans Glacier, in the vicinity of the Polish Polar Station Hornsund, Spitsbergen. Artificial quakes were generated at a point of central location between the seismometer sites. The calculated velocities are: VP = 3,620 m/s, VS = 1,780 m/s.

Impacts of supraglacial lakes and snowmelt on glacier velocity on the example of the Baltoro Glacier in Pakistan

Millionen von Menschen in Pakistan leben entlang des Indus und sind auf das Schmelzwasser der Gletscher im Karakorum angewiesen. Gletscherschmelzwasser steuert ebenso die Gletscherdynamik, die eine relevante Information über die Entwicklung der Gletscher in einem sich ändernden Klima ist, an.
