‘Calving laws’, ‘sliding laws’ and the stability of tidewater glaciers (2007, background): “…general model of calving glacier dynamics is a formidable challenge involving some of the most stubborn problems in glaciology, including realistic parameterization of calving processes, the ‘grounding-line problem’ (e.g. Vieli and Payne, 2005) and the ‘unresolved sliding problem’ (Weertman, 1979).”
A three-dimensional full Stokes model of the grounding line dynamics: effect of a pinning point beneath the ice shelf (2011, background): “Until 2005, as demonstrated by Vieli and Payne (2005), none of the numerical models available was able to describe properly the grounding line migration.”
Antarctic grounding line mapping from differential satellite radar interferometry (2011, background): “zone is a major challenge in modern numerical modeling of ice sheet flow [Gillet‐Chaulet and Durand, 2010; Vieli and Payne, 2005].”
Marine ice-sheet dynamics. Part 1. The case of rapid sliding (2007, methodology): “The model used here, originally due to Muszynski & Birchfield (1987) and MacAyeal (1989), has been employed in a number of numerical studies of coupled ice-sheet–iceshelf systems (e.g. Vieli & Payne 2005), the novelty in our paper being a consistent approach using matched asymptotics.”
Ice sheet grounding line dynamics: Steady states, stability, and hysteresis (2007, methodology): “[126] By contrast with the numerical algorithms discussed by Vieli and Payne [2005], we do not differentiate the flotation condition in (A7) with respect to t to obtain an explicit evolution equation for xg, but retain it in its initial form.”
Marine ice sheet dynamics: Hysteresis and neutral equilibrium (2009, background): “[5] An abundant literature dealing with the coupling between grounded ice sheet and floating ice shelf, and identifying this transition zone as a crucial control of the marine ice sheet dynamics, was motivated by the initial discussion proposed byWeertman [e.g., Van der Veen, 1985;Hindmarsh, 1993, 1”
A physically based calving model applied to marine outlet glaciers and implications for the glacier dynamics (2010, background): “The assumption is made that basal drag depends on sliding velocity and effective basal pressure (Bindschadler 1983; Van der Veen and Whillans, 1996; Vieli and Payne, 2005).”
Grounding line movement and ice shelf buttressing in marine ice sheets (2009, background): “This suggests that numerical inconsistencies cannot be attributed to underresolution of stress gradients in the grounding line transition zone alone, which were suggested by Schoof [2007b] as the cause of the inconsistent results obtained in previous work [e.g., Vieli and Payne, 2005].”
