Recent (2018–2021) glaciological, hydrological and geomorphological landscape changes of Hailuogou Glacier tongue, southeastern Tibetan Plateau

open access: yesJournal of Maps, 2023
Glaciers in the Tibetan Plateau are melting at an unprecedented recently rate in the context of global warming. Time-sequenced landform mapping for the Hailuogou Glacier, a partly debris-covered glacier in the southeastern Tibetan Plateau, shows the ...

Halving of Swiss glacier volume since 1931 observed from terrestrial image photogrammetry [PDF]

open access: yesThe Cryosphere, 2022
The monitoring of glaciers in Switzerland has a long tradition, yet glacier changes during the 20th century are only known through sparse observations.

A new global gridded glacier dataset based on the Randolph Glacier Inventory version 6.0

open access: yesJournal of Glaciology, 2021
Gridded glacier datasets are essential for various glaciological and climatological research because they link glacier cover with the corresponding gridded meteorological variables.

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 ...

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 ...

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.

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

open access: yes, 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.

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.

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.
