Discovery of the Fastest Ice Flow along the Central Flow Line of Austre Lovénbreen, a Poly-thermal Valley Glacier in Svalbard

Remote Sensing, 2019
Ice flow velocity is a sensitive indicator of glacier variations both controlling and representing the delivery of ice and affecting the future stability of ice masses in a warming climate.

Assessing ice-cliff backwasting and its contribution to total ablation of debris-covered Miage glacier, Mont Blanc massif, Italy [PDF]

, 2014
Continuous surface debris cover strongly reduces the ablation of glaciers, but high melt rates may occur at ice cliffs that are too steep to hold debris.

Simulating climatic mass balance, seasonal snow development and associated freshwater runoff in the Kongsfjord basin, Svalbard (1980–2016)

Journal of Glaciology, 2018
The Kongsfjord basin in northwest Svalbard is the site of a number of interdisciplinary studies concerned with the effect of fresh water from seasonal snow and glacier melt on the physical and biological environment.

Microbial nitrogen cycling on the Greenland Ice Sheet [PDF]

, 2012
Nitrogen inputs and microbial nitrogen cycling were investigated along a 79 km transect into the Greenland Ice Sheet (GrIS) during the main ablation season in summer 2010. The depletion of dissolved nitrate and production of ammonium (relative to icemelt)

Future Retreat of Great Aletsch Glacier and Hintereisferner – application of a full-Stokes model to two valley glaciers in the European Alps [PDF]

The Cryosphere
We simulate the future evolution of two valley glaciers in the European Alps over the course of the 21st century. The model setup combines a numerical realization of full-Stokes ice dynamics coupled to a surface energy balance model forced with the ...

Centreline and cross-glacier air temperature variability on an Alpine glacier: assessing temperature distribution methods and their influence on melt model calculations

Journal of Glaciology, 2017
The spatio-temporal distribution of air temperature over mountain glaciers can demonstrate complex patterns, yet it is often represented simplistically using linear vertical temperature gradients (VTGs) extrapolated from off-glacier locations. We analyse

Calving laws and where to find them

Journal of Glaciology
Calving from tidewater glaciers and ice shelves is an important component of global mass balance and may contribute significantly to future sea-level rise.

Modelling of hydrological response to climate change in glacierized Central Asian catchments [PDF]

, 2007
The arid lowlands of Central Asia are highly dependent on the water supplied by the Tien Shan mountains. Snow and ice storage make large contributions to current runoff, particularly in summer.

Simulating seasonal evolution of subglacial hydrology at a surging glacier in the Karakoram

Journal of Glaciology
Glacier motion, retreat and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that ...

Glacier mass variation and its effect on surface runoff in the Beida River catchment during 1957–2013

Journal of Glaciology, 2017
Using in-situ measured data from Qiyi Glacier, in combination with meteorological and run-off data from stations, a distributed degree-day model was developed for 631 investigated glaciers in the Beida River catchment to explore glacier mass change and ...
