Improved representation of laminar and turbulent sheet flow in subglacial drainage models

Journal of Glaciology
Subglacial hydrology models struggle to reproduce seasonal drainage patterns that are consistent with observed subglacial water pressures and surface velocities. We modify the standard sheet-flow parameterization within a coupled sheet–channel subglacial

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.

Assessing the dynamic changes and the effect of buoyancy of lake-terminating Yanong Glacier in the southeastern Tibetan Plateau with UAV surveys

Journal of Hydrology: Regional Studies
Study region: Yanong Glacier, a lake-terminating glacier, in the southeastern Tibetan Plateau. Study focus: Previous researches had indicated higher mass loss of lake-terminating glaciers than land-terminating glaciers over the past few decades. However,

Glacier volume response time and its links to climate and topography based on a conceptual model of glacier hypsometry [PDF]

The Cryosphere, 2009
Glacier volume response time is a measure of the time taken for a glacier to adjust its geometry to a climate change. It has been previously proposed that the volume response time is given approximately by the ratio of glacier thickness to ablation at ...

Synchronous terminus change of East Antarctic outlet glaciers linked to climatic forcing [PDF]

, 2013
In recent years there has been a growing trend of acceleration, thinning and retreat of ocean-terminating outlet glaciers in both the Greenland and West Antarctic Ice Sheets, resulting in an increasing contribution to sea level rise.

First Alps-wide reconstruction of LGM glacial sediment transport enabled by GPU-accelerated particle tracking [PDF]

Earth Surface Dynamics
Reconstructing the transport histories and provenances of glacial sediments and ice-contact deposits (e.g. tills, moraines) in formerly glaciated regions remains a major challenge, particularly at icefield- to ice-sheet scales and over multi-millennial ...

Cryospheric ecosystems: a synthesis of snowpack and glacial research [PDF]

, 2015
The fourteen letters that contributed to this focus issue on cryospheric ecosytems provide an excellent basis for considering the state of the science following a marked increase in research attention since the new millennium.

The impact of supraglacial ice cliff and pond formation on debris-free, tropical glacier mass loss

Journal of Glaciology
Tropical Andean glaciers provide an important flux of freshwater to communities living both in high-altitude Cordillera and population centres downstream in countries such as Peru and Bolivia. Glacier recession threatens the sustainability of these water

Modelling glacier-bed overdeepenings and possible future lakes for the glaciers in the Himalaya—Karakoram region

Annals of Glaciology, 2016
Surface digital elevation models (DEMs) and slope-related estimates of glacier thickness enable modelling of glacier-bed topographies over large ice-covered areas.
