Methanogenesis in subglacial sediments
Environmental Microbiology Reports, 2010Summary Methanogenic archaea have a unique role in Earth's global carbon cycle as producers of the greenhouse gas methane (CH 4 ). However, despite the fact that ice covers 11% of Earth's continental landmass, evidence for methanogenic activity in subglacial environments has

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.

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.

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 ...

The Biogeochemical Legacy of Arctic Subglacial Sediments Exposed by Glacier Retreat
Global Biogeochemical Cycles, 2022During past periods of advance, Arctic glaciers and ice sheets overrode soil, sediments, and vegetation and buried significant stores of organic matter (OM); these glaciers are now shrinking rapidly due to climate warming.

Sedimentation in a Permian Subglacial Channel
SEPM Journal of Sedimentary Research, 1981ABSTRACT An unusual sediment accumulation in the glaciogene Permian near Bacchus Marsh, Victoria is interpreted as representing the development and infilling of a subglacial channel. This polymictic conglomerate has a thickness of more than 50 m and rests within glacial and periglacial Permian strata.

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 ...
