Sustained retreat of the Pine Island Glacier [PDF]

, 2013
We use satellite observations to show that, between 1992 and 2011, the Pine Island Glacier hinge line retreated at a rate of 0.95 ± 0.09 km yr−1 despite a progressive steepening and shoaling of the glacier surface and bedrock slopes, respectively, which ...

Influence of glacier inventories on ice thickness estimates and future glacier change projections in the Tian Shan range, Central Asia

Journal of Glaciology, 2023
The Tian Shan mountain range, known as the water towers of Central Asia, plays a key role in local water supply, yet large uncertainties remain about the amount of water that is stored in its glaciers.

Ice Volume Characterization using Long-Wavelength Airborne PolSAR Data [PDF]

, 2012
The interest in studying land ice for glaciological and climate change research has increased in recent years. The need of information on a global scale makes synthetic aperture radar (SAR) suitable for these studies.

Glacier volume estimation as an ill-posed inversion [PDF]

Journal of Glaciology, 2014
AbstractEstimating a glacier’s volume by inferring properties at depth (e.g. bed topography or basal slip) from properties observed at the surface (e.g. area and slope) creates a calculation instability that grows exponentially with the size of the glacier.

A comparison of glacier melt on debris-covered glaciers in the northern and southern Caucasus [PDF]

, 2011
The glacier coverage in the Caucasus Mountains underwent considerable changes during the last decades. In some regions, the observed reduction in glacier area is comparable to those in the European Alps and the extent of supra-glacial debris increased on

Modeling the Response of the Langtang Glacier and the Hintereisferner to a Changing Climate Since the Little Ice Age

Frontiers in Earth Science, 2019
This study aims at developing and applying a spatially-distributed coupled glacier mass balance and ice-flow model to attribute the response of glaciers to natural and anthropogenic climate change.

Comparison of Hydrological Patterns between Glacier-Fed and Non-Glacier-Fed Lakes on the Southeastern Tibetan Plateau

Remote Sensing, 2021
Lakes on the Tibetan Plateau have experienced variations over the last several decades, and the delineation of lake dynamics is favorable for the regional water cycle and can serve as important information for plateau environmental research.

The physical basis of glacier volume‐area scaling [PDF]

Journal of Geophysical Research: Solid Earth, 1997
Ice volumes are known for only a few of the roughly 160,000 glaciers worldwide but are important components of many climate and sea level studies which require water flux estimates. A scaling analysis of the mass and momentum conservation equations shows that glacier volumes can be related by a power law to more easily observed glacier surface areas ...

Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]

, 2002
The relationship between the evolution of subglacial drainage system morphology and spatial patterns of glacier surface velocity was investigated using dye tracing experiments and ground surveying throughout the 1995 melt season at Haut Glacier d'Arolla,
