Computationally efficient subglacial drainage modelling using Gaussian process emulators: GlaDS-GP v1.0

Geoscientific Model Development
Abstract. Subglacial drainage models represent water flow at the ice–bed interface through coupled distributed and channelized systems to determine water pressure, discharge, and drainage system geometry. While they are used to understand processes such as the relationship between surface melt and ice flow, the number of uncertain model parameters and ...

Micromorphology and microstructural analysis of polyphase deformation of tills, West Runton [PDF]

, 2011
Glacially deformed sediments have been studied intensely since the 1970’s (van der Meer and Menzies, 2011), and with this, the use of micromorphology as a component technique (Menzies and Maltman, 1992; van der Meer, 1993; Menzies, 2000; Phillips and ...

Southern Ocean warming: Increase in basal melting and grounded ice loss [PDF]

, 2013
We apply a global finite element sea ice/ice shelf/ocean model (FESOM) to the Antarctic marginal seas to analyze projections of ice shelf basal melting in a warmer climate.

Subglacial processes at the fringe of the last Scandinavian Ice Sheet in central Poland derived from macro‐ and micro‐sedimentological proxies

Boreas
Geological information contained in tills is important for deciphering processes that operated under past ice sheets and helps to constrain the fundamentals of glacial erosion, transport and deposition.

Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]

Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...
