The Causes and Implications of Microstructures in Glacial Sediments [PDF]
, 1998 This thesis examines how microstructures in glaciogenic sediments reflect the processes forming them, and how these microstructures then affect the conditions around them, through a series of field studies, laboratory tests, models, and statistical ...

The finite-volume method in computational rheology [PDF]
, 2012 The finite volume method (FVM) is widely used in traditional computational fluid dynamics (CFD), and many commercial CFD codes are based on this technique which is typically less demanding in computational resources than finite element methods (FEM ...

GRACE constraints on Earth rheology of the Barents Sea and Fennoscandia [PDF]
Solid Earth, 2020 The Barents Sea is situated on a continental margin and was home to a large ice sheet at the Last Glacial Maximum. Studying the solid Earth response to the removal of this ice sheet (glacial isostatic adjustment; GIA) can give insight into the subsurface

Variational inference of ice shelf rheology with physics-informed machine learning
Journal of Glaciology, 2023 Floating ice shelves that fringe the coast of Antarctica resist the flow of grounded ice into the ocean. One of the key factors governing the amount of flow resistance an ice shelf provides is the rigidity (related to viscosity) of the ice that ...

High-resolution LiDAR mapping of glacial landforms and ice stream lobes in Finland [PDF]
Bulletin of the Geological Society of Finland, 2017 Newly available high resolution airborne LiDAR (Light Detection And Ranging) technology is generating unprecedented next-generation imagery of Earth surface features. LiDAR datasets are being employed by the Geological Survey of Finland (GTK) as part of

Upward Expansion of Supra-Glacial Debris Cover in the Hunza Valley, Karakoram, During 1990 ∼ 2019
Frontiers in Earth Science, 2020 Supra-glacial debris cover is key to glacier ablation through increasing (thin debris layer) or decreasing (thick debris layer) melt rates, thereby regulating the mass balance of a glacier and its meltwater runoff.

Viscous and elastic buoyancy stresses as drivers of ice-shelf calving
Journal of Glaciology, 2020 The Antarctic Ice Sheet loses mass via its ice shelves predominantly through two processes: basal melting and iceberg calving. Iceberg calving is episodic and infrequent, and not well parameterized in ice-sheet models.

Magnetic anisotropy and debris-dependent rheological heterogeneity within stratified basal ice
Journal of Glaciology, 2019 Basal ice of glaciers and ice sheets frequently contains a well-developed stratification of distinct, semi-continuous, alternating layers of debris-poor and debris-rich ice.

Development of crystal orientation fabric in the Dome Fuji ice core in East Antarctica: implications for the deformation regime in ice sheets [PDF]
The Cryosphere, 2022 The crystal orientation fabric (COF) of a polar ice sheet has a significant effect on the rheology of the ice sheet. With the aim of better understanding the deformation regime of ice sheets, the work presented here investigates the COF in the upper 80 %
