Geometric Controls of Tidewater Glacier Dynamics [PDF]
Abstract. Retreat of marine outlet glaciers often initiates depletion of inland ice through dynamic adjustments of the upstream glacier. The local topography of a fjord may promote or inhibit such retreat, and therefore fjord geometry constitutes a critical control on ice sheet mass balance.

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 ...

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

Fundamentals of glacier dynamics [PDF]
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.

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

Summer Dynamics of Microbial Diversity on a Mountain Glacier
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.

Dynamics of glacier calving at the ungrounded margin of Helheim Glacier, southeast Greenland. [PDF]
During summer 2013 we installed a network of 19 GPS nodes at the ungrounded margin of Helheim Glacier in southeast Greenland together with three cameras to study iceberg calving mechanisms. The network collected data at rates up to every 7 s and was designed to be robust to loss of nodes as the glacier calved.

Ice‐Dynamical Glacier Evolution Modeling—A Review
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.

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.
