Basal mechanics of ice streams: Insights from the stick‐slip motion of Whillans Ice Stream, West Antarctica (2009, methodology): “However, there has been some debate about extrapolating the small-scale laboratory studies of till, O(10 1–1 m), to field scale, O(1–105 m) [e.g., Fowler, 2002; Tulaczyk et al., 2000b].”
The effect of cavitation on glacier sliding (2005, background): “The mechanics of such glaciers may then be similar to ice streams underlain by weak till (Tulaczyk et al. 2000b), where lateral shear stresses rather than basal shear stress dominate force balance (Echelmeyer et al. 1994; Raymond 1996; Schoof 2005; Truffer et al. 2001).”
Glacier-surge mechanisms promoted by a hydro-thermodynamic feedback to summer melt (2015, background): “Input of surface meltwater during consecutive summers progressively raises the pore-water pressure within the sediment, reducing its shear strength and favouring rapid destabilization (Clarke et al., 1984; Tulaczyk et al., 2000).”
Changes in west Antarctic ice stream velocities: Observation and analysis (2002, methodology): “[57] Both the viscous-deforming bed [Alley et al., 1987; Blankenship et al., 1987] and the plastic bed models [Kamb, 1991; Tulaczyk et al., 2000a, 2000b] transport till downstream, although till fluxes differ by roughly one order of magnitude [Tulaczyk et al., 2001].”
Shallow shelf approximation as a “sliding law” in a thermomechanically coupled ice sheet model (2008, result): “The underlying physical model is supported by recent observations [Joughin et al., 2004b; Tulaczyk et al., 2000] and theory [Schoof , 2006a] for ice streams.”
