Mineral deformation and subglacial processes on ice-bedrock interface of Hailuogou Glacier
Chinese Science Bulletin, 2009 Hailuogou Glacier is located in a warm and humid maritime environment. It is large and moves very fast. The bottom of the glacier slides intensively and the temperature at the bottom approaches the pressure melting point. Therefore, there are abundant melting water and debris which act as effective “grinding tools” for glacial abrasion.

A preliminary Scanning Electron Microscope (SEM) study of magnetite surface microtextures from the Wahianoa moraines, Mt Ruapehu, New Zealand. [PDF]
, 2010 Scanning electron microscope (SEM) of quartz micro‐textures has routinely been used to identify the depositional environment of sediments in areas of former ice‐sheet glaciation.

Defining Petrophysical Units of the Palmer Deep Sites from Leg 178 [PDF]
, 2002 Palmer Deep, on the inner continental shelf southwest of Anvers Island off the Antarctic Peninsula, is a glacially overdeepened basin consisting of three subbasins. Two sites, 1098 and 1099, were drilled in the Palmer Deep area.

Glacial erosion: status and outlook
Annals of Glaciology, 2019 Glacier-erosion rates range across orders of magnitude, and much of this variation cannot be attributed to basal sliding rates. Subglacial till acts as lubricating ‘fault gouge’ or ‘sawdust’, and must be removed for rapid subglacial bedrock erosion. Such

Climatic control on the peak discharge of glacier outburst floods
, 2007 Lakes impounded by natural ice dams occur in many glacier regions. Their sudden emptying along subglacial paths can unleash similar to 1 km(3) of floodwater, but predicting the peak discharge of these subglacial outburst floods ('jokulhlaups') is ...

Transient glacier dynamics and subglacial hydro-mechanical processes
, 2023 The Cryosphere, encompassing elements like sea ice, permafrost, snow, glaciers, and ice sheets, faces a grave threat from ongoing climate change and can significantly impact ecosystems, human lives, and livelihoods. Understanding their dynamics is essential to predict their future and inform mitigation strategies.

Simulating seasonal evolution of subglacial hydrology at a surging glacier in the Karakoram
Journal of GlaciologyGlacier motion, retreat and glacier hazards such as surges and glacial lake outburst floods (GLOFs) are likely underpinned by subglacial hydrology. Recent advances in subglacial hydrological modeling allow us to shed light on subglacial processes that ...
