Near-margin ice thickness and subglacial water routing, Leverett Glacier, Greenland
Ice thickness measurements near the margin of the Greenland Ice Sheet (GrIS) are relatively sparse, presenting issues for modeling ice-flow dynamics, ice-sheet change, and subglacial hydrology.

Global Warming and Mass Extinctions Associated With Large Igneous Province Volcanism
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Some knowledge on and parameters of China's alpine hydrology
Based on field data from the Hulu Watershed in the Qilian Mountains of China,five types of experiential parameters of alpine hydrology are calibrated: ① wind-induced factors of gauge-measured precipitation; ② threshold air temperature (day and half ...

Worldwide version-controlled database of glacier thickness observations [PDF]
Although worldwide inventories of glacier area have been coordinated internationally for several decades, a similar effort for glacier ice thicknesses was only initiated in 2013.

An energy-balance model for debris-covered glaciers including heat conduction through the debris layer [PDF]
Extensive covers of supraglacial debris are often present in glacier ablation areas, and it is essential to assess exactly how the debris affects glacier melt rates.

Arctic tidewater glaciers are retreating, serving as key indicators of global warming. This study aims to assess how subglacial hydrology affects glacier front retreat by comparing two glacier–fjord models of the Hansbreen glacier: one incorporating a ...

Brief communication: Heterogenous thinning and subglacial lake activity on Thwaites Glacier, West Antarctica [PDF]
A system of subglacial lakes drained on Thwaites Glacier from 2012–2014. To improve coverage for subsequent drainage events, we extended the elevation and ice-velocity time series on Thwaites Glacier through austral winter 2019.

Subsurface hydrology of an overdeepened cirque glacier [PDF]
AbstractTo investigate the subsurface hydrological characteristics of an overdeepened cirque glacier, nine boreholes were drilled to the bed of West Washmawapta Glacier, British Columbia, Canada, in summer 2007. All holes were surveyed with a video camera, and four were subsequently instrumented with a combination of pressure transducers, thermistors ...

Hydrological controls on diurnal ice flow variability in valley glaciers [PDF]
This paper uses a combination of field data and three-dimensional modeling to investigate the spatial variability in basal conditions required to induce observed fluctuations in diurnal ice velocity at Haut Glacier d'Arolla, Switzerland.

Transient evolution of basal drag during glacier slip
Glacier slip is usually described using steady-state sliding laws that relate drag, slip velocity and effective pressure, but where subglacial conditions vary rapidly transient effects may influence slip dynamics.
