Melting of the glacier base during a small-volume subglacial rhyolite eruption: evidence from Blahnukur, Iceland. [PDF]

, 2002
Although observations of recent volcanic eruptions beneath Vatnajokull, Iceland have improved the understanding of ice deformation and meltwater drainage, little is known about the processes that occur at the glacier base.

Fast Glacier Flow

Eos, Transactions American Geophysical Union, 1987
An AGU Chapman Conference on Fast Glacier Flow was held at Whistler Village, Canada, from May 4 to 8, 1986. The timing of the conference seemed particularly propitious because of results of recent observational programs, such as the breakup of the tidewater Columbia Glacier in Alaska, the imbalance of Ice Stream B in Antarctica and the existence of ...

Air temperature distribution and energy balance modelling of a debris-covered glacier [PDF]

, 2016
Near-surface air temperature is an important determinant of the surface energy balance of glaciers that is often represented by constant linear temperature gradients in models.

Susceptibility Analysis of Glacier Debris Flow Based on Remote Sensing Imagery and Deep Learning: A Case Study along the G318 Linzhi Section

Sensors, 2023
Glacial debris flow is a common natural disaster, and its frequency has been increasing in recent years due to the continuous retreat of glaciers caused by global warming.

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.

A distributed energy-balance melt model of an alpine debris-covered glacier [PDF]

, 2014
Distributed energy-balance melt models have rarely been applied to glaciers with extensive supraglacial debris cover. This paper describes the development of a distributed melt model and its application to the debris-covered Miage glacier, western ...

Scenario Simulation of Glacier Collapse in the Amnye Machen Mountains, Qinghai–Tibetan Plateau

Geosciences
Simulating potential glacier collapses can provide crucial support for local disaster prevention and mitigation efforts. The Xiaomagou Glacier in the Amnye Machen Mountains, Qinghai–Tibetan Plateau, has experienced five collapses in the past two decades.

Multi-decadal basal slip enhancement at Saskatchewan Glacier, Canadian Rocky Mountains

Journal of Glaciology, 2023
Glacier motion responds dynamically to changing meltwater inputs, but the multi-decadal response of basal sliding to climate remains poorly constrained due to its sensitivity across multiple timescales.

Glacier Flow in a Curving Channel [PDF]

Journal of Glaciology, 1987
AbstractThe flow of a glacier along a channel of constant longitudinal curvature is analyzed using analytical and finite-element methods. Channels of various cross–sectional shape are investigated, ranging from a simple rectangular form with zero shear traction along the bed to realistic profiles taken from Blue Glacier, Washington.

Velocities of Major Outlet Glaciers of the Patagonia Icefield Observed by TerraSAR-X [PDF]

, 2008
The capabilities of TerraSAR-X data for feature tracking by amplitude correlation over glacier surfaces are investigated. Methodical aspects of the amplitude correlation approach are described.
