Dynamics of lake-terminating glaciers in the Himalaya and Southeastern Tibet between 1990 and 2020

Journal of Glaciology
Lake-terminating glaciers retreat and thin faster than land-terminating glaciers, yet their long-term dynamics remain underexplored. Using multi source–remote sensing data combined with glacier velocity and elevation change datasets, we investigated ...

Utilising seismic station internal GPS for tracking surging glacier sliding velocity

Journal of Glaciology
Glacier ice flux is a key indicator of mass balance; therefore, accurate monitoring of ice dynamics is essential. Satellite-based methods are widely used for glacier velocity measurements but are limited by satellite revisit frequency.

Automated detection and temporal monitoring of crevasses using remote sensing and their implications for glacier dynamics

Annals of Glaciology, 2016
Detailed studies on temporal changes of crevasses and their linkage with glacier dynamics are scarce in the Himalayan context. Observations of temporally changing surficial crevasse patterns and their orientations are suggestive of the processes that ...

Shifts in glacier dynamics during land-to-lake terminus transition in western Patagonia

Journal of Glaciology
Land-to-lake glacier terminus transition can alter glacier dynamics and enhance mass loss. However, the magnitude and timing of dynamic changes during this transition remain poorly constrained, especially in hyperhumid regions such as western Patagonia ...

Multisensor Glacier Surface Classification Using Confidence-Aware Explainable Inverse-Mapping Neural Network

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Mapping snow cover at the end of the ablation season allows us to extract the snow line altitude (SLA). The SLA is an important proxy for the equilibrium line altitude of a glacier and an indicator of glacier health.

Dynamics of Erebus Glacier Tongue [PDF]

Annals of Glaciology, 1982
Recent measurements conducted on Erebus Glacier Tongue (EGT) have enabled improvements to be made to previous analyses of earlier data (Holdsworth 1974). The use of LANDSAT imagery and controlled aerial photography up to 1978 have enabled glacier flow rates and hence strain-rates to be determined more accurately than before.

Characterization of the near-surface air temperature dynamics over glaciers using thermal infrared measurements

Frontiers in Earth Science
Alpine glaciers are undergoing rapid mass loss, primarily driven by rising summer air temperatures. However, the glacier microclimate, especially the role of atmospheric dynamics near the surface and turbulent fluxes, is not adequately understood.

Systems thinking to adapt tourism to climate change: Application to summer glacier skiing in Switzerland

Annals of Tourism Research Empirical Insights
Climate change affects mountain tourism and summer glacier skiing, a highly vulnerable activity. This paper explores the complex dynamics affecting summer glacier skiing in Swiss Alpine destinations. The methodology involved conducting 26 semi-structured

Geomorphology of the Évettes alpine glacial landsystem: documenting the legacy of the Little Ice Age in the Western Alps, France

Journal of Maps
The end of the Little Ice Age (LIA) in the nineteenth century triggered glacial retreat across the Northern Hemisphere, leaving behind sediment-landform assemblages that preserve records of glacier behavior.

Surge of the Bivachny Glacier in 2012–2015

Лëд и снег, 2015
The surge of the Bivachny Glacier that occurred in 2012–2015 is analyzed with the use of photographing performed from International Space Station in 2001–2015 together with data of the satellite monitoring of 1972–2000.
