Sustained retreat of the Pine Island Glacier [PDF]

open access: yes, 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 ...

Spatio-temporal variability in geometry and geodetic mass balance of Jostedalsbreen ice cap, Norway

open access: yesAnnals of Glaciology, 2023
The Jostedalsbreen ice cap is mainland Europe's largest ice cap and accommodates 20% (458 km2 in 2019) of the total glacier area of mainland Norway.

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

open access: yes, 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 ...

94 GHz Radar Backscatter Characteristics of Alpine Glacier Ice

open access: yesGeophysical Research Letters, 2023
Measuring the radar backscatter characteristics of glacier ice at different frequencies and incidence angles is fundamental to predicting the glacier mapping performance of a sensor. However, such measurements at 94 GHz do not exist.

Subglacial drainage processes at a High Arctic polythermal valley glacier [PDF]

open access: yes, 2005
Dye-tracer experiments undertaken over two summer melt seasons at polythermal John Evans Glacier, Ellesmere Island, Canada, were designed to investigate the character of the subglacial drainage system and its evolution over a melt season. In both summers,

Glacier shrinkage across High Mountain Asia

open access: yesAnnals of Glaciology, 2016
An assessment of glacier shrinkage (reduction of area) for all of High Mountain Asia requires a complete compilation of measured rates of change and also a methodology for objective comparison of rates.

CONCEPTUAL FRAMEWORK OF COMBINED PIXEL AND OBJECT-BASED METHOD FOR DELINEATION OF DEBRIS-COVERED GLACIERS [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Delineation of the glacier is an important task for understanding response of glaciers to climate. In Himalayan region, most of the glaciers are covered with debris.

The distribution of basal motion beneath a High Arctic polythermal glacier [PDF]

open access: yes, 2003
The longitudinal pattern of surface velocity of a large, predominantly colds polythermal glacier (John Evans Glacier, Ellesmere Island, Canada) was measured over summer and winter periods.

Glacier classification from Sentinel-2 imagery using spatial-spectral attention convolutional model

open access: yesInternational Journal of Applied Earth Observations and Geoinformation, 2021
Glaciers are critical components of the cryosphere and most sources of water. The Sentinel-2 imagery provides an efficient and cost-effective way for the production of inventories of glaciers.

Influence of subglacial drainage system evolution on glacier surface motion: Haut Glacier d'Arolla, Switzerland [PDF]

open access: yes, 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,
