Glacier-surge mechanisms promoted by a hydro-thermodynamic feedback to summer melt (2015, background): “However, recent studies suggest meltwater connections from the surface to the bed through cold ice of substantial thickness (e.g. Das et al., 2008; Clason et al., 2014).”
Convection-Driven Melting near the Grounding Lines of Ice Shelves and Tidewater Glaciers (2011, background): “Surface meltwater is known to drain to the bed of the Greenland Ice Sheet, imparting a seasonal variability to the motion of ice in the ablation zone (Zwally et al. 2002; Das et al. 2008; Joughin et al. 2008), and at least some of this meltwater eventually reaches the grounding lines of the tidewate”
Ice-sheet acceleration driven by melt supply variability (2010, background): “This is favoured by strong diurnal cycles(5) or frequent rain events,(17) both of which are more likely at lower latitudes, or if the ice sheet develops numerous surface lakes that drain abruptly.(18) I have developed a new model that captures drainage channelization under glaciers and ice sheets, a”
