Committed retreat: controls on glacier disequilibrium in a warming climate

Journal of Glaciology, 2018
The widespread retreat of mountain glaciers is a striking emblem of recent climate change. Yet mass-balance observations indicate that many glaciers are out of equilibrium with current climate, meaning that observed retreats do not show the full response

Analysis of Antarctic Peninsula glacier frontal ablation rates with respect to iceberg melt-inferred variability in ocean conditions

Journal of Glaciology, 2020
Marine-terminating glaciers on the Antarctic Peninsula (AP) have retreated, accelerated and thinned in response to climate change in recent decades. Ocean warming has been implicated as a trigger for these changes in glacier dynamics, yet little data ...

Fundamentals of glacier dynamics [PDF]

Geomorphology, 2001
Glaciers form when snow melts and refreezes, or is compressed, to form ice. Spreading under their own weight, they flow seaward, channeled along preferred routes by the shape or composition of the underlying bedrock. Though we don't know why, some ice streams flow rapidly within slower‐moving ice in Greenland and Antarctica.

Satellite-observed surging dynamics of North Kunchhang Glacier I in the Eastern Karakoram [PDF]

The Cryosphere
Frequent glacier surges are a distinctive characteristic of Karakoram glaciers, with their occurrence increasing recently, significantly impacting glacier morphology and dynamics.

Microbial community dynamics in the forefield of glaciers [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2014
Retreating ice fronts (as a result of a warming climate) expose large expanses of deglaciated forefield, which become colonized by microbes and plants. There has been increasing interest in characterizing the biogeochemical development of these ecosystems using a chronosequence approach.

Summer Dynamics of Microbial Diversity on a Mountain Glacier

mSphere, 2022
Microbial diversity on mountain glaciers is an underexplored component of global biodiversity. Microbial presence and activity can also reduce the surface albedo or reflectiveness of glaciers, causing them to absorb more solar radiation and melt faster, which in turn drives more microbial activity.

Terminus dynamics at an advancing glacier: Taku Glacier, Alaska [PDF]

Journal of Glaciology, 2009
AbstractTaku Glacier, Alaska, USA, is currently in the advance stage of the tidewater glacier cycle. We investigated the near-terminus dynamics by measuring surface velocities, surface elevation changes, ice thickness and ablation. Velocities vary on sub-daily, diurnal, seasonal and interannual timescales.

Alarming recession of glaciers in Bhilangna basin, Garhwal Himalaya, from 1965 to 2014 analysed from Corona and Cartosat data

Geomatics, Natural Hazards & Risk, 2017
Himalayan glaciers are showing reliable evidences of climate change. Glacier status in Bhilangna basin of Garhwal Himalaya were mapped from Corona and Cartosat satellite images acquired in 1965 and 2014.

Ice‐Dynamical Glacier Evolution Modeling—A Review

Reviews of Geophysics, 2022
AbstractGlaciers play a crucial role in the Earth System: they are important water suppliers to lower‐lying areas during hot and dry periods, and they are major contributors to the observed present‐day sea‐level rise. Glaciers can also act as a source of natural hazards and have a major touristic value.

Evaluation of surface mass-balance records using geodetic data and physically-based modelling, Place and Peyto glaciers, western Canada

Journal of Glaciology, 2023
Reliable, long-term records of glacier mass change are invaluable to the glaciological and climate-change communities and used to assess the importance of glacier wastage on streamflow. Here we evaluate the in-situ observations of glacier mass change for
