On thin glacial ice: New Austrian Glacier Inventory shows accelerating glacier shrinkage and 31 % area loss within two decades [PDF]

The Cryosphere
We present the new Austrian glacier inventory, AGI5. Glacier outlines were manually digitized from high-resolution orthoimagery and digital elevation models, using older inventories as a baseline.

Combined Use of Sentinel-1 and Sentinel-2 for Glacier Mapping: An Application Over Central East Alps

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022
The systematic monitoring of glaciers is essential to both evaluate water resource availability and better understand the effects of climate change. The increased speed of glacier changes observed in the past few years requires a more frequent update of ...

Glacier shrinkage in the Alps continues unabated as revealed by a new glacier inventory from Sentinel-2 [PDF]

Earth System Science Data, 2020
The ongoing glacier shrinkage in the Alps requires frequent updates of glacier outlines to provide an accurate database for monitoring, modelling purposes (e.g.

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,

A satellite-derived glacier inventory for North Asia

Annals of Glaciology, 2016
This study outlines a consistent methodology for identifying glacier surfaces from Landsat 5, 7 and 8 imagery that is applied to map all mainland North Asian glaciers, providing the first methodologically consistent and complete glacier inventory for the

The Greater Caucasus Glacier Inventory (Russia, Georgia and Azerbaijan) [PDF]

The Cryosphere, 2018
There have been numerous studies of glaciers in the Greater Caucasus, but none that have generated a modern glacier database across the whole mountain range. Here, we present an updated and expanded glacier inventory at three time periods (1960, 1986,

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.

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 ...

Assessment of area, volume and ELA of glacial systems in Northeast Russia from satellite images in the beginning of XXI century

Лëд и снег, 2015
The paper compares remotely sensed glacier inventories of the Byrranga, Suntar-Khayata, and Chersky ranges (2003), Koryak Highland and Chukotka mountains (2008) with data from the Inventory of Glaciers of the USSR (1945–1985).

Glacier area changes in Northern Eurasia

Environmental Research Letters, 2014
Glaciers are widely recognized as key indicators of climate change. Recent evidence suggests an acceleration of glacier mass loss in several key mountain regions.
