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.

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.

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.

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]

, 2012
Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

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 ...

Downwasting and supraglacial lake evolution on the debris-covered Ngozumpa Glacier, Khumbu Himal, Nepal [PDF]

, 2015
In recent decades, the downwasting of several debris-covered glaciers in the Himalaya has led to the formation of large and potentially hazardous moraine- dammed lakes.

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.

Recent glacier decline in the Kerguelen Islands (49°S, 69°E) derived from modeling, field observations, and satellite data [PDF]

, 2015
Date of Acceptance: 28/02/2015The retreat of glaciers in the Kerguelen Islands (49°S, 69°E) and their associated climatic causes have been analyzed using field data and Moderate Resolution Imaging Spectroradiometer (MODIS) satellite images to validate a ...
