Investigating Antarctic subglacial hydrologic processes from marine sediment cores
2023Understanding processes operating beneath glacial ice is imperative for holistic knowledge of glaciated regions and for accurately projecting future behavior of and sea-level contributions from the Antarctic Ice Sheet. Evolution of subglacial hydrologic networks is one such process where knowledge gaps persist, in large part because of the challenges ...

Striated clast pavements: Products of deforming subglacial sediment?
Geology, 1991Studies of modern glaciers have recently drawn attention to the importance of subglacial sediment deformation to glacier dynamics and processes. Inferences regarding the probable shear strength of this sediment imply that large clasts may in some cases sink to underlying rigid sediment, where abrasion by overlying deforming sediment could occur.

Subglacial hydrology and sediment transport at Bondhusbreen, southwest Norway
Geological Society of America Bulletin, 1985Tunnels driven, in rock under the glacier Bondhusbreen in Norway, and thence upward to the ice-rock interface, provide a rare opportunity to study a subglacial drainage system. Early in the melt season, suspended sediment discharges in the subglacial water channels are large, and channels apparently change position.

A new subglacial sediment deformation discharge rule
Movement of glaciers over (soft) sediment beds can deform the underlying sediment, transporting it in the direction of glacier flow. This subglacial sediment discharge can vary spatially, leading to net erosion in some areas and deposition in others—stripping some areas free of sediment, while others accumulate thick deposits— ...Lucas Zoet +2 more
