Geophysical parameters estimation with TerraSAR-X of outlet glaciers in the Transantarctic Mountains
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012We discuss TerraSAR-X observations of three Transantarctic Mountain (TAM) outlet glaciers: Byrd, Nimrod and Beardmore. High resolution TerraSAR-X data acquired over the area in late 2009 and late 2010 using left looking mode were processed to generate detailed 2D ice velocity maps by means of speckle tracking.

Internal structure and trend of glacier change assessed by geophysical investigations
Environmental Earth Sciences, 2012Ground-penetrating radar (GPR) is a useful tool for mapping the thickness, morphology and structure of alpine glaciers. Englacial information obtained during a field survey of the Koxkar Glacier in Tian Shan, China, in June 2008 was retrieved from GPR profile data.

Geophysical survey of Johnsons Glacier (Antarctica): Comparing seismic and RES data
SEG Technical Program Expanded Abstracts 2000, 2000Seismic and radio-echo sounding data have been acquired along coincident profiles at the temperate Johnsons Glacier (Livingston Island, South Shetland Islands, Antarctica). Seismic data have been processed and the results provide information about ice-thickness and bedrock topography.

A Geophysical and Petrophysical Appraisal of a Possible Origin of Himalayan Rivers and Glaciers
Journal Geological Society of India, 1989Abstract Recent investigations of the seismic, electrical conductivity and rheological structures of the continental crust favours the presence of a fluid-rich layer at the mid and lower crustal levels. Such layers may exhibit high electrical conductivity, seismic reflectivity and ductility.

The centenary of World War I triggered several and relevant studies in the fields of Conflict Archeology. The research scenario becomes even more challenging when the study site is located at high altitude in the Alps were past battles and also the modern research should face extreme conditions.

Ice thickness of the West Kunlun glaciers revealed by airborne geophysical survey
Glacier ice thickness models are fundamental to studies of glaciology, hydrology, and climatology. They play a key role in estimating ice volume, simulating future glacier evolution, and projecting meltwater runoff changes. However, ice thickness measurements (e.g., ice penetrating radar) only cover about 14% of global glacier area and disparity existsJunjun Yang, Qing Shu

The glaciers of the European Alps are currently affected by large mass losses, due to unfavorable climatic conditions. Glacier areas and volumes rapidly decrease and the bedrock tends to outcrop, causing morphological changes and fragmentation of most ice bodies.

Permafrost and Periglacial Processes, 2006
AbstractThe composition of rock glaciers was sounded by a combination of conventional geophysical methods near the lower limit of mountain permafrost in the Swiss Alps. P‐wave velocity, direct current (DC) resistivity and year‐round ground surface temperatures were measured on 32 talus‐derived rock glaciers.
