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.

Science, 1964
From physical measurements on glaciers and experimental studies of ice properties a framework of concept and theory is being built which bids fair to place glaciers among the more quantitatively understandable phenomena in the earth sciences. Measurements of flow velocity, deformation and stress, ice thickness and channel configuration, temperature ...

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 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.

High-Resolution Geophysical Images of Static Crustal Structure and Time-Dependent Glacier Flow
2022Availability of better data has always been a fundamental driver of the progress in geophysical observational studies, and motivates development of new methodologies in utilizing emerging datasets to obtain key information that existing methodologies cannot provide. In this thesis, I present two lines of studies. In Chapter 2, I present the development

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.

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.

Internal Structure of Four Rock Glaciers in the Northern Tien Shan from Geophysical Investigations
The cryosphere in Central Asia is critically important as a source of water. Widespread glacier mass loss has been observed across the Tien Shan in response to rising temperatures, raising concerns over future water resources. The Northern Tien Shan, situated along the border of Kazakhstan and Kyrgyzstan hosts almost 700 rock glaciers, including a ...Ella Wood +6 more
