Time-dependence of the spatial pattern of accumulation rate in East Antarctica deduced from isochronic radar layers using a 3-D numerical ice flow model (2011)
Journal Article
Leysinger Vieli, G., Hindmarsh, R., Siegert, M., & Bo, S. (2011). Time-dependence of the spatial pattern of accumulation rate in East Antarctica deduced from isochronic radar layers using a 3-D numerical ice flow model. Journal of Geophysical Research, 116(F2), https://doi.org/10.1029/2010jf001785

In East Antarctica surface mass balance data can only be obtained from the sparsely distributed ice cores when considering time periods greater than a few decades. Observations of internal layers measured by airborne ice penetrating radar, in princip...

A numerical study of glacier advance over deforming till (2010)
Journal Article
Leysinger Vieli, G., & Gudmundsson, G. (2010). A numerical study of glacier advance over deforming till. The Cryosphere, 4(3), 359-372. https://doi.org/10.5194/tc-4-359-2010

The advance of a glacier over a deforming sediment layer is analysed numerically. We treat this problem as a contact problem involving two slowly-deforming viscous bodies. The surface evolution of the two bodies, and of the contact interface between... Read More about A numerical study of glacier advance over deforming till.

Draping or overriding: The effect of horizontal stress gradients on internal layer architecture in ice sheets (2006)
Journal Article
Hindmarsh, R., Leysinger Vieli, G., Raymond, M., & Gudmundsson, G. (2006). Draping or overriding: The effect of horizontal stress gradients on internal layer architecture in ice sheets. Journal of Geophysical Research, 111, https://doi.org/10.1029/2005jf000309

Internal isochronic layers in ice sheets sensed by radar show two characteristic relationships to the basal topography: Either they override it, with layers above the crests of rises lying essentially flat, or they drape over it, with the layers foll...

On estimating length fluctuations of glaciers caused by changes in climatic forcing (2004)
Journal Article
Leysinger Vieli, G., & Gudmundsson, G. (2004). On estimating length fluctuations of glaciers caused by changes in climatic forcing. Journal of Geophysical Research, 109, https://doi.org/10.1029/2003jf000027

The reaction of alpine glaciers to shifts in the equilibrium line altitude (ELA) is calculated by using a two-dimensional numerical model to solve the full equations for the velocity and stress fields (full-system model) in the absence of basal motio...
