Erosion by an Alpine glacier.
Assessing the impact of glaciation on Earth's surface requires understanding glacial erosion processes. Developing erosion theories is challenging because of the complex nature of the erosion processes and the difficulty of examining the ice/bedrock interface of contemporary glaciers. We demonstrate that the glacial erosion rate is proportional to the ice-sliding velocity squared, by quantifyin...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

While basal icequakes associated with glacier motion have been detected under Antarctica for several decades, there remains very little evidence of stick-slip motion for Alpine glaciers. Here we analyzed 2357 basal icequakes that were recorded at Glacier d’Argentière (Mont-Blanc Massif) between February and November of 2012, and that are likely to be associated with basal sliding. These events ...
متن کاملRapid subglacial erosion beneath Pine Island Glacier, West Antarctica
[1] We present measurements of ice thickness, gravimetry and surface elevation on Pine Island Glacier, West Antarctica, separated by a period of 49 years. At one station, on the main trunk of the glacier we measured a surface elevation lowering with no significant change in ice thickness. We interpret these as indicating subglacial erosion of 31.8 13.4 m at this location, at a mean rate over th...
متن کاملQuantifying sediment transfer between the front of an active alpine rock glacier and a torrential gully
The present contribution describes results from the quantification of transferred sediment volumes between the front of an active rock glacier and a torrential gully. The focus is set on the methodological approach which combines terrestrial laser scanning (TLS) generated digital terrain models (DTM) and geodetic field surveys. The aim is to compare high resolution DTMs from different dates in ...
