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.

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.

Mid-Term Monitoring of Glacier’s Variations with UAVs: The Example of the Belvedere Glacier

Remote Sensing, 2021
Recently, Unmanned Aerial Vehicles (UAV) have opened up unparalleled opportunities for alpine glacier monitoring, as they allow for reconstructing extensive and high-resolution 3D models.

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 ...

How sensitive are mountain glaciers to climate change? Insights from a block model

Journal of Glaciology, 2018
Simple models of glacier volume evolution are important in understanding features of glacier response to climate change, due to the scarcity of data adequate for running more complex models on a global scale.

Volume–area scaling vs flowline modelling in glacier volume projections [PDF]

Annals of Glaciology, 2007
AbstractVolume–area scaling provides a practical alternative to ice-flow modelling to account for glacier size changes when modelling the future evolution of glaciers; however, uncertainties remain as to the validity of this approach under non-steady conditions.

New estimate of volume of glaciers worldwide [PDF]

Eos, Transactions American Geophysical Union, 2012
As climate warms, melting mountain glaciers are likely to contribute significantly to sea level rise over the next decades, but how much they will contribute remains uncertain, as the total volume of Earth's mountain glaciers is not precisely known. Some studies have estimated the total volume of water stored in glaciers worldwide using statistical ...

Regional and global volumes of glaciers derived from statistical upscaling of glacier inventory data [PDF]

Journal of Geophysical Research: Earth Surface, 2010
Very few global‐scale ice volume estimates are available for mountain glaciers and ice caps, although such estimates are crucial for any attempts to project their contribution to sea level rise in the future. We present a statistical method for deriving regional and global ice volumes from regional glacier area distributions and volume area scaling ...

On the estimation of ice volume of alpine glaciers

Ice and Snow, 2015
Volume (V) − area (S) scaling approach (V = kSp, where V and S are obtained from direct measurements) is widely used for ice storage assessments in glacier-mountain systems. Accuracy of this approach was tested using surface area and volume dataset for 121 glaciers of different morphological type and sizes in Altay Mountains.

Volume, formation and sedimentation of future glacier lakes in Switzerland [PDF]

, 2022
Abstract. Ongoing climate change and associated glacier retreat is causing rapid environmental change, including shifts in high-alpine landscapes. Glacier lakes, which can form in topographical depressions left behind by glacier retreat, are prominent features within such landscapes.
