Glacier-Surface Velocity Derived Ice Volume and Retreat Assessment in the Dhauliganga Basin, Central Himalaya – A Remote Sensing and Modeling Based Approach

Frontiers in Earth Science, 2019
Himalayan glaciers are a storehouse of fresh water and play a significant role in influencing the runoff through numerous perennial rivers flowing over the Indo-Gangetic plains, providing freshwater to the second largest populated country in the world ...

Glacier thickness estimations of alpine glaciers using data and modeling constraints [PDF]

The Cryosphere, 2019
Abstract. Advanced knowledge of the ice thickness distribution within glaciers is of fundamental importance for several purposes, such as water resource management and the study of the impact of climate change. Ice thicknesses can be modeled using ice surface features, but the resulting models can be prone to considerable uncertainties.

Permafrost Favorability Index: Spatial Modeling in the French Alps Using a Rock Glacier Inventory

Frontiers in Earth Science, 2017
In the present study we used the first rock glacier inventory for the entire French Alps to model spatial permafrost distribution in the region. The inventory, which does not originally belong to this study, was revised by the authors in order to obtain ...

Assessment of glacier lakes development potential in the Central Caucasus

Лëд и снег, 2020
Glacier mass loss and consequent terminus retreat lead to formation and growth of glacier lakes. In Caucasus outbursts of glacial lakes formed in recent decades have led to human casualties and significant damage. In this study the location and volume of

Sensitivity analysis of a King George Island outlet glacier, South Shetlands, Antarctica [PDF]

Anais da Academia Brasileira de Ciências, 2023
The Lange glacier is an outlet glacier situated in the Admiralty Bay, King George Island, Peninsula Antarctica. It retreated about 1 km since the 1950s.

Simulation of Historic Glacier Variations with a Simple Climate-Glacier Model [PDF]

Journal of Glaciology, 1988
AbstractGlacier variations during the last few centuries have shown a marked coherence over the globe. Characteristic features are the maximum stand somewhere in the middle of the nineteenth century, and the steady retreat afterwards (with some minor interruptions depending on the particular region).

A framework for three-dimensional dynamic modeling of mountain glaciers in the Community Ice Sheet Model (CISM v2.2) [PDF]

Geoscientific Model Development
It is essential to improve our understanding of glaciers and their effects on sea levels, ecosystems, and freshwater resources in a changing climate. To this end, we implemented a framework for three-dimensional, high-resolution, regional-scale glacier ...

Detection and characterization of discontinuous motion on Thompson Glacier, Canadian High Arctic, using synthetic aperture radar speckle tracking and ice-flow modeling

Journal of Glaciology, 2023
We investigate unusual discontinuous glacier motion on Thompson Glacier, Umingmat Nunaat, Arctic Canada, using synthetic aperture radar (SAR) images and ice-flow modeling.

Modeled Climate-Induced Glacier Change in Glacier National Park, 1850–2100 [PDF]

BioScience, 2003
consequences of glacier retreat by creating spatially explicit models of the creation and ablation of glaciers and of the response of vegetation to climate change. We determined the melt rate and spatial distribution of glaciers under two possible future climate scenarios, one based on carbon dioxide‐induced global warming and the other on a linear ...

Debris cover effect on the evolution of Northern Caucasus glaciers in the 21st century

Frontiers in Earth Science, 2023
More than 13% of the area of the Caucasus glaciers is covered by debris affecting glacier mass balance. Using the Caucasus as example, we introduce a new model configuration that incorporates a physically-based subroutine for the evolution of ...
