Quantification of seasonal and diurnal dynamics of subglacial channels using seismic observations on an Alpine glacier [PDF]
The Cryosphere, 2020 Water flowing below glaciers exerts a major control on glacier basal sliding. However, our knowledge of the physics of subglacial hydrology and its link with sliding is limited because of lacking observations. Here we use a 2-year-long dataset made of on-

Spectral roughness of glaciated bedrock geomorphic surfaces: Implications for glacier sliding [PDF]
, 2000 A microroughness meter (MRM) was used to measure the high-frequency roughness of a number of geomorphic surfaces in the forefield of Glacier de Tsanfleuron, Switzerland.

Near-margin ice thickness and subglacial water routing, Leverett Glacier, Greenland
Arctic, Antarctic, and Alpine Research, 2018 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.

Hydrology of a land-terminating Greenlandic outlet glacier
, 2013 Hydrology is recognised as an important component of the glacial system in alpine environments. In particular, the subglacial drainage of surface meltwaters is known to exert a strong influence on the motion of glaciers and on their capacity to erode the underlying bedrock.

Debris cover and surface melt at a temperate maritime alpine glacier: Franz Josef Glacier, New Zealand [PDF]
, 2012 Melt rates on glaciers are strongly influenced by the presence of supraglacial debris, which can either enhance or reduce ablation relative to bare ice.

Some knowledge on and parameters of China's alpine hydrology
Shui kexue jinzhan, 2014 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 ...

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 ...

Worldwide version-controlled database of glacier thickness observations [PDF]
Earth System Science Data, 2020 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.

Connect Store: A fully coupled 3D model of ice flow, calving, subglacial hydrology and ice-ocean interactions applied to Store Glacier, Greenland [PDF]
, 2020 This dissertation uses the 3D, finite-element, full-Stokes, open-source model Elmer/Ice to investigate the coupled dynamics of the ice-calving-subglacial-hydrology-plume system at Store Glacier, a large, fast-flowing tidewater outlet glacier on the west ...

Transient evolution of basal drag during glacier slip
Journal of Glaciology, 2022 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.
