A global database of historic glacier lake outburst floods

Earth System Science Data, 2023
. Ongoing atmospheric warming has accelerated glacier mass loss in many mountain regions worldwide. Glacier lakes trap part of the glacial meltwater and have increased by about 50 % in number and area since the 1990s.

Crevasses triggered on Pine Island Glacier by drilling through an exceptional melt layer [PDF]

, 2010
The basic theory of crevasse formation suggests that crevasses initiate at or near the surface. However, due to variations in stress with depth, it has been suggested that it is possible for crevasses to initiate at depths of 10–30m.

Combination of UAV and terrestrial photogrammetry to assess rapid glacier evolution and conditions of glacier hazards

, 2017
Tourists and hikers visiting glaciers all year round face hazards such as the rapid formation of collapses at the terminus, typical of such a dynamically evolving environment.

Including debris cover effects in a distributed model of glacier ablation [PDF]

, 2012
Distributed glacier melt models generally assume that the glacier surface consists of bare exposed ice and snow. In reality, many glaciers are wholly or partially covered in layers of debris that tend to suppress ablation rates.

Intra-annual and intra-seasonal flow dynamics of a High Arctic polythermal valley glacier [PDF]

, 2002
Measurements of surface dynamics on polythermal John Evans Glacier, Nunavut, Canada, over two winter periods and every 7-10 days throughout two melt seasons (June-July 2000, 2001) provide new insight into spatio-temporal patterns of High Arctic glacier ...

Glacier variations at Aru Co in western Tibet from 1971 to 2016 derived from remote-sensing data

Journal of Glaciology, 2018
Twin glaciers collapsed in 2016 near Aru Co, western Tibet and caused extreme loss to human beings. In this study, we attempted to track the dynamics of glaciers in the region, for example the glacier area and mass changes in Aru Co for the period 1971 ...

Formation of a large ice depression on Dålk Glacier (Larsemann Hills, East Antarctica) caused by the rapid drainage of an englacial cavity

Journal of Glaciology, 2021
In the afternoon of 30 January 2017, a catastrophic outburst flood occurred in the Larsemann Hills (Princess Elizabeth Land, East Antarctica). The rapid drainage of both a thin supraglacial layer of water (near Boulder Lake) and Lake Ledyanoe into the ...

Temporal variations in the ice volume of Xiao Dongkemadi Glacier, central Tibetan Plateau, from 1969 to 2020

Journal of Glaciology
Glaciers play a crucial role in the Asian Water Tower, underscoring the necessity of accurately assessing their mass balance and ice volume to evaluate their significance as sustainable freshwater resources.

Detection of crevassed areas with minimum geometric information: Vernagtferner case study

Journal of Glaciology, 2023
Crevasses pose severe risks for mountaineers and field glaciologists. Smaller cracks between 0.5 and 2 m are still dangerous, but often not visible in medium resolution satellite imagery.

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
