Geometry and drainage of a retreating glacier overlying and recharging a karst aquifer, Tsanfleuron-Sanetsch, Swiss Alps

Acta Carsologica, 2010
Alpine glaciers store large amounts of freshwater contributing to groundwater recharge during warmer periods, but the inter­actions between glaciers and aquifers have rarely been inves­tigated in detail.

Using PlanetScope-derived time-series elevation models and orthophotos to track glacier 3D dynamics in mid-latitude mountain regions

GIScience & Remote Sensing
Assessing glacier surface height changes provides crucial insights into glacier mass loss and the impact of climate variability. Remote sensing images play a vital role in providing data points for monitoring.

Diverse landscapes beneath Pine Island Glacier influence ice flow

Nature Communications, 2017
Projecting the future retreat and thus global sea level contributions of Antarctica’s Pine Island Glacier is hampered by a poor grasp of what controls flow at the ice base.

Reconstructing Glacier Surge Kinematics Using a Numerical Ice‐Flow Model Applied to the Dusty Glacier, St. Elias Mountains, Canada

Geophysical Research Letters
Long‐term records of the flow patterns and dynamics of surge‐type glaciers improve our understanding of their underlying dynamic processes, and are critical to better resolve their contribution to a changing cryosphere.

WAVES OF ACCELERATED MOTION IN A GLACIER APPROACHING SURGE: THE MINI-SURGES OF

, 2014
. Periods of dramatically accelerated motion, in which the flow velocity increases suddenly from about 55 cm/d to a peak of 100-300 cm/d and then decreases gradually over the course of a day, occurred repeatedly during June and July 1978-81 in Variegated

Role of glaciers in watershed hydrology: a preliminary study of a "Himalayan catchment" [PDF]

The Cryosphere, 2010
A large number of Himalayan glacier catchments are under the influence of humid climate with snowfall in winter (November–April) and south-west monsoon in summer (June–September) dominating the regional hydrology.

Numerical simulation of glacier terminus evolution using the dual action principle for momentum balance

Journal of Glaciology
The momentum conservation equation for glacier flow can be described through minimization of an action functional. Several software packages for glacier flow modeling use this action principle in the design of numerical solution procedures.

Biotic Acceleration of Glacier Melting in Yala Glacier 9 Langtang Region, Nepal Himalaya

, 2020
In some Himalayan glaciers, the microbial production on the glacier surface is so large during the monsoon season that the surface of the ablation area is covered with a dark coloured mud-like material which mainly consists of algae and bacteria.

Global glacier changes

, 2008
Changes in glaciers and ice caps provide some of the clearest evidence of climate change, and as such they constitute key variables for early detection strategies in global climate-related observations.
