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.

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 ...

Assessing the catastrophic break-up of Briksdalsbreen, Norway, associated with rapid climate change

, 2011
Recent research has raised concerns about the potential influence of rapid climate change on the stability of major ice sheets. The behaviour of glaciers is determined largely by the processes and conditions operating at their base.

Modeling 2m air temperatures over mountain glaciers: Exploring the influence of katabatic cooling and external warming [PDF]

, 2015
Air temperature is one of the most relevant input variables for snow and ice melt calculations. However, local meteorological conditions, complex topography, and logistical concerns in glacierized regions make the measuring and modeling of air ...

Short-term variability in Greenland Ice Sheet motion forced by time-varying meltwater inputs: implications for the relationship between subglacial drainage system behavior and ice velocity. [PDF]

, 2012
High resolution measurements of ice motion along a 120 km transect in a land-terminating section of the GrIS reveal short-term velocity variations (<1 day), which are forced by rapid variations in meltwater input to the subglacial drainage system from

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

Testing hypotheses of the cause of peripheral thinning of the Greenland Ice Sheet: is land-terminating ice thinning at anomalously high rates? [PDF]

, 2008
Recent observations have shown that the periphery of the Greenland ice sheet (GrIS) is thinning rapidly and that this thinning is greatest around marine-terminating outlet glaciers. Several theories have been proposed which provide a link between climate

Coherent scatterers detection: application over glacier terrain using TerraSAR-X time series data [PDF]

, 2011
This paper investigates the detection of Coherent Scatterers (CSs) in ice and glacier terrain by means of TerraSAR-X time series data in the test site of the Helheim Glacier in Greenland.

Estimation of the Surface Velocity Field of Temperate Glaciers Using Airborne SAR Interferometry [PDF]

, 2008
This paper presents a methodology to process airborne interferometric SAR data to measure surface velocity fields of temperate glaciers. First, a solution based on multi-squint is proposed to estimate residual motion errors (inaccuracies of the ...

Proximity to active volcanoes enhances glacier velocity

Communications Earth & Environment
AbstractVolcanic heating is predicted by theory to affect the velocity of nearby glaciers. However, conclusive studies on a large scale are lacking. Here, we conduct a global comparison of the velocities of glaciers near active volcanoes (i.e. within 5 km) and those located elsewhere ( > 5 km from an active volcano).
