Ice-stream stability on a reverse bed slope (2012)
Journal Article
Jamieson, S., Vieli, A., Livingstone, S., Ó Cofaigh, C., Stokes, C., Hillenbrand, C., & Dowdeswell, J. (2012). Ice-stream stability on a reverse bed slope. Nature Geoscience, 5(11), 799-802. https://doi.org/10.1038/ngeo1600

Marine-based ice streams whose beds deepen inland are thought to be inherently unstable. This instability is of particular concern because significant portions of the marine-based West Antarctic and Greenland ice sheets are losing mass and their retr...

Antarctic palaeo-ice streams (2012)
Journal Article
Livingstone, S., O'Cofaigh, C., Stokes, C., Hillenbrand, C., Vieli, A., & Jamieson, S. (2012). Antarctic palaeo-ice streams. Earth-Science Reviews, 111(1-2), 90-128. https://doi.org/10.1016/j.earscirev.2011.10.003

We review the geomorphological, sedimentological and chronological evidence for palaeo-ice streams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors controlling grou...

The evolution of the subglacial landscape of Antarctica (2010)
Journal Article
Jamieson, S., Sugden, D., & Hulton, N. (2010). The evolution of the subglacial landscape of Antarctica. Earth and Planetary Science Letters, 293(1-2), 1-27. https://doi.org/10.1016/j.epsl.2010.02.012

The aim is to investigate the evolution of the subglacial landscape of Antarctica using an ice sheet and erosion model. We identify different stages of continental glaciation and model the erosion processes associated with each stage. The model links...

The impact of parametric uncertainty and topographic error in ice-sheet modelling (2008)
Journal Article
Hebeler, F., Purves, R., & Jamieson, S. (2008). The impact of parametric uncertainty and topographic error in ice-sheet modelling. Journal of Glaciology, 54(188), 889-919. https://doi.org/10.3189/002214308787779852

Ice-sheet models (ISMs) developed to simulate the behaviour of continental-scale ice sheets under past, present or future climate scenarios are subject to a number of uncertainties from various sources. These sources include the conceptualization of... Read More about The impact of parametric uncertainty and topographic error in ice-sheet modelling.

Modelling landscape evolution under ice sheets (2008)
Journal Article
Jamieson, S., Hulton, N., & Hagdorn, M. (2008). Modelling landscape evolution under ice sheets. Geomorphology, 97(1-2), 91-108. https://doi.org/10.1016/j.geomorph.2007.02.047

We use an ice sheet model (GLIMMER) with an erosion component to examine the evolution of landscapes under ice sheets over long time scales in hypothetical situations. GLIMMER is a fully coupled thermomechanical 3-dimensional ice sheet model with a s... Read More about Modelling landscape evolution under ice sheets.

Cenozoic Landscape evolution of the Lambert basin, East Antarctica: the relative role of rivers and ice sheets (2005)
Journal Article
Jamieson, S., Hulton, N., Sugden, D., Payne, A., & Taylor, J. (2005). Cenozoic Landscape evolution of the Lambert basin, East Antarctica: the relative role of rivers and ice sheets. Global and Planetary Change, 45(1-3), 35-49. https://doi.org/10.1016/j.gloplacha.2004.09.015

The inception of the Antarctic Ice Sheet at around 34 Ma followed a period of globally warm climatic conditions. The efficacy of glacial erosion since this time is modelled using BEDMAP Antarctic digital elevation data and seismically estimated offsh...

Tectonic forcing of longitudinal valleys in the Himalaya: morphological analysis of the Ladakh Batholith, North India (2004)
Journal Article
Jamieson, S., Sinclair, H., Kirstein, L., & Purves, R. (2004). Tectonic forcing of longitudinal valleys in the Himalaya: morphological analysis of the Ladakh Batholith, North India. Geomorphology, 58(1-4), 49-65. https://doi.org/10.1016/s0169-555x%2803%2900185-5

Longitudinal valleys form first order topographic features in many mountain belts. They are commonly located along faults that separate tectonic zones with varying uplift histories. The Indus Valley of Ladakh, northern India, runs northwestwards foll...

Erosion-driven uplift in the Gamburtsev Subglacial Mountains of East Antarctica (1999)
Journal Article
Paxman, G., Watts, A., Ferraccioli, F., Jordan, T., Bell, R., Jamieson, S., & Finn, C. (1999). Erosion-driven uplift in the Gamburtsev Subglacial Mountains of East Antarctica. Earth and Planetary Science Letters, 452, 1-14. https://doi.org/10.1016/j.epsl.2016.07.040

The relative roles of climate and tectonics in mountain building have been widely debated. Central to this debate is the process of flexural uplift in response to valley incision. Here we quantify this process in the Gamburtsev Subglacial Mountains,... Read More about Erosion-driven uplift in the Gamburtsev Subglacial Mountains of East Antarctica.
