Particle and aggregate mobility in till: Microscopic evidence of subglacial processes

Quaternary Science Reviews, 1997
Abstract Microscopic studies of tills show that the deforming bed of glaciers is made up of minute rotational elements or wheels, consisting of a nucleus alone or a nucleus with spiralling arms of fine grains. These fine grains can move from one wheel to the next, providing a process of high grain mobility within a deforming subglacial till ...

Subglacial processes from drumlins in Clew Bay, western Ireland

Earth Surface Processes and Landforms, 2015
AbstractInterpretation of subglacial processes and environments can be usefully informed by the stratigraphy and structures of sediments preserved within drumlins, and the down‐ice variability of these sediments. Drumlins in Clew Bay, western Ireland, were formed by westward late Pleistocene ice flow onto the Atlantic shelf, but the depositional ...

An investigation of subglacial shear zone processes from Weybourne, Norfolk, UK

Quaternary Science Reviews, 2007
Abstract The glacial sediments of north Norfolk are a type site for subglacial deforming bed sediments. This investigation focussed on subglacial shear zone process at the field and thin section scale, in order to understand subglacial processes, as well as considering the implications for regional stratigraphies.

Subglacial drainage modelling and Bayesian calibration using Gaussian Process emulators

Subglacial drainage models sensitively depend on the values of numerous uncertain parameters. However, the computation time associated with running these models makes it difficult to quantify the associated uncertainty in model outputs and to use field data to calibrate parameter values.
