A Numerical Model for Fluvial Transport of Subglacial Sediment [PDF]

Journal of Geophysical Research F: Earth Surface, 2019
Sediment discharge from glaciers impacts downstream aquatic habitats, hydropower operations, and river infrastructure. Since discharge of subglacial sediment will evolve in response to glacier retreat, estimating future subglacial sediment dynamics is of great relevance.

Technologies for Retrieving Sediment Cores in Antarctic Subglacial Settings [PDF]

Philosophical Transactions Series A, Mathematical, Physical, and Engineering Sciences, 2016
Accumulations of sediment beneath the Antarctic Ice Sheet contain a range of physical and chemical proxies with the potential to document changes in ice sheet history and to identify and characterize life in subglacial settings. Retrieving subglacial sediments and sediment cores presents several unique challenges to existing technologies.

Methanogenesis in subglacial sediments

Environmental Microbiology Reports, 2010
Summary 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

Sedimentation in a Permian subglacial channel

Journal of Sedimentary Research, 1981
Abstract 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.
