Geophysical evidence of multiple glacier advances in Lago Fagnano (54°S), southernmost Patagonia

Quaternary Science Reviews, 2010
The Island of Tierra del Fuego, at the southernmost extreme of Patagonia, is located in one of the most extensively glaciated areas of the Southern Hemisphere outside Antarctica during the late Pleistocene. The Lago Fagnano region, at w54 30 0 S and w68 W, has experienced several phases of glacier growth and retreat since the Last Glacial Maximum ...

Processes of crevasse formation and the dynamics of calving glaciers : a study at Breiđamerkurjökull

, 2009
A new model proposed by Benn et al. (2006, 2007) explains the dynamics of calving glaciers based on a new sliding law and a calving criterion modified from a crevasse depth model. In this thesis three key elements of this model are tested: 1) the role

The Causes and Implications of Microstructures in Glacial Sediments [PDF]

, 1998
This thesis examines how microstructures in glaciogenic sediments reflect the processes forming them, and how these microstructures then affect the conditions around them, through a series of field studies, laboratory tests, models, and statistical ...

Signal characteristics of surface seismic explosive sources near the West Antarctic Ice Sheet divide

Journal of Glaciology
Seismic imaging in 3-D holds great potential for improving our understanding of ice sheet structure and dynamics. Conducting 3-D imaging in remote areas is simplified by using lightweight and logistically straightforward sources.

Helheim 2006: Integrated Geophysical Observations of Glacier Flow

, 2006
During the summer field season, 2006, we undertook a pilot geophysical experiment at Helheim Glacier, East Greenland, in which we deployed a network of GPS instruments on and around the glacier to measure the ice deformation field as a function of time. The experiment was motivated by the discovery of a new class of earthquakes occurring at glaciers in

Glacier Changes on the Pik Topografov Massif, East Sayan Range, Southeast Siberia, from Remote Sensing Data

, 2018
Small mountain glaciers represent the most abundant class in many glaciarized areas around the world; however, less is known about their recent area changes under climatic variability of the last decades.

A geophysical and glaciological survey of the highest tropical mountain glaciers (Mt. Huascarán, Andes)

Journal of Glaciology
Abstract Peru hosts a significant portion of the world’s tropical glaciers, which are undergoing rapid mass loss due to climate change. Knowledge of the ice volume and bedrock topography of these glaciers is important for predicting changes in glacier dynamics, runoff, and interpreting ice-core records. This study presents results from glaciological

Using Sea-Level Data to Constrain the Contribution of the Greenland Ice Sheet to Contemporary and Recent Sea-Level Change [PDF]

, 2010
Due to the potentially wide-reaching impacts on climate and sea-level change of a declining Greenland Ice Sheet (GrIS), the mass balance of the past decade has caused concern that the ice sheet is reacting to increased temperatures of the industrial era ...
