Microstructures of sediment flow deposits and subglacial sediments: a comparison
Boreas, 2001Microstructural analysis of glacial deposits has recently been used as a research tool to determine sediment genesis. However, the occurrence of microstructures in deposits of known origin has not been sufficiently documented, hindering our ability to confidently interpret microstructures in sediments of unknown origin.

Organic Remains in Finnish Subglacial Sediments
Quaternary Research, 1995AbstractMany sites in Fennoscandia contain pre-Late Weichselian beds of organic matter, located mostly in the flanks of eskers. It is a matter of debate whether these fragmentary beds were deposited in situ, or whether they were deposited elsewhere and then picked up and moved by glacial ice.

Subglacial processes, sediments and landforms—an introduction
Sedimentary Geology, 1994This introduction provides an overview of research presented at the Symposium on Subglacial Processes, Sediments and Landforms held at the University of Ulster, July 1992. Particular attention is focused on new developments in understanding the subglacial environment and elaboration of current controversies concerning the formation of subglacial ...

Subglacial Sediment Dispersal and till Composition
The Journal of Geology, 1987Dispersal of subglacial sediment down-ice from its bedrock source assumes the form of a negative exponential decay curve. Dispersal decay curves can be quantified by their decay constants, half-distances ( = half-lives), and total transport distances.

Sedimentation in a subglacial lake, Enniskerry, eastern Ireland
Sedimentary Geology, 1994Abstract Field relationships between a subglacial lake fill from the Enniskerry basin, eastern Ireland, provide evidence for dynamic links between the sedimentary fill, regional subglacial meltwater flow and regional ice dynamics. The basin fill (6–7 km2) forms an integral part of an extensive (30 km) subglacial meltwater system which developed ...

Behaviour of subglacial sediment and basal ice in a cold glacier
Geological Society, London, Special Publications, 2000Abstract Tunnels in glaciers offer unique opportunities for examining basal processes. At Suess Glacier in the Taylor Valley, Antarctica, a 25 m tunnel excavated into the bed of the glacier provides access to a 3.2m thick basal zone and the ice-substrate contact.

The impact of snow line altitude on subglacial sediment export
2023Large Alpine glaciers typically export significant quantities of subglacially eroded sediment to their downstream environments via meltwater streams. The supply of this glaciogenically-produced sediment has an extensive impact on landform genesis and evolution; downstream ecology and ecosystem succession; river morphology and flood risk management ...

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.
