RHEOLOGY OF GLACIER ICE

Le Journal de Physique Colloques, 1985
A new method for calculating the stress field in bounded ice shelves is used to compare strain rate and deviatoric stress on the Ross Ice Shelf, Antarctica. The analysis shows that strain rate (per second) increases as the third power of deviatoric stress (in newtons per square meter), with a constant of proportionality equal to 2.3 x 10

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing [PDF]

, 2013
In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an increasing contribution to sea level rise.

Precipitation phase drives seasonal and decadal snowline changes in high mountain Asia

Environmental Research Letters
Snow cover is of key importance for water resources in high mountain Asia (HMA) and is expected to undergo extensive changes in a warming climate.

Weathering Dynamics Under Contrasting Greenland Ice Sheet Catchments

Frontiers in Earth Science, 2019
Chemical weathering dynamics in Greenland Ice Sheet (GrIS) catchments are largely unknown, due to a scarcity of field data. This paper presents the most comprehensive study to date of chemical weathering rates from four GrIS catchments of contrasting ...

Modeling and Compensation of the Penetration Bias in InSAR DEMs of Ice Sheets at Different Frequencies

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Interferometric synthetic aperture radar (InSAR) is able to provide important information for the characterization of the surface topography of glaciers and ice sheets.

A review of topographic controls on moraine distribution [PDF]

, 2014
Ice-marginal moraines are often used to reconstruct the dimensions of former ice masses, which are then used as proxies for palaeoclimate. This approach relies on the assumption that the distribution of moraines in the modern landscape is an accurate ...

Younger Dryas glacier advances in the tropical Andes driven by increased precipitation

Scientific Reports
There is currently a debate about the timing and drivers of former glacier behaviour and climate change in the tropical Andes. Using 10Be dating we determined the ages of 21 boulders on moraines in the Santa Cruz Valley, Peru (∼10°S, altitudes ~ 4100 to ~

Results from the Ice Thickness Models Intercomparison eXperiment Phase 2 (ITMIX2)

Frontiers in Earth Science, 2021
Knowing the ice thickness distribution of a glacier is of fundamental importance for a number of applications, ranging from the planning of glaciological fieldwork to the assessments of future sea-level change.

Mountain glacier-to-rock glacier transition

Global and Planetary Change, 2019
Abstract In many of the world's high mountain systems, glacier recession in response to climate change is accompanied by a paraglacial response whereby glaciers are undergoing a transition to rock glaciers. We hypothesise that this transition has important implications for hydrological resources in high mountain systems and the surrounding lowlands ...
