Ice flow at a location in the equilibrium zone of the west-central Greenland Ice Sheet accelerates above the midwinter average rate during periods of summer melting. The near coincidence of the ice acceleration with the duration of surface melting, followed by deceleration after the melting ceases, indicates that glacial sliding is enhanced by rapid migration of surface meltwater to the ice-bedrock interface. Interannual variations in the ice acceleration are correlated with variations in the… 

Large and Rapid Melt-Induced Velocity Changes in the Ablation Zone of the Greenland Ice Sheet

Continuous Global Positioning System observations reveal rapid and large ice velocity fluctuations in the western ablation zone of the Greenland Ice Sheet, which suggests that the englacial hydraulic system adjusts constantly to the variable meltwater input, which results in a more or less constant ice flux over the years.

Decay of the Greenland Ice Sheet due to surface-meltwater-induced acceleration of basal sliding

Simulations of the Greenland Ice Sheet are carried out with a high-resolution version of the ice-sheet model SICOPOLIS for several global-warming scenarios for the period 1990-2350. In particular,

Self-regulation of ice flow varies across the ablation area in south-west Greenland

Abstract. The concept of a positive feedback between ice flow and enhanced melt rates in a warmer climate fuelled the debate regarding the temporal and spatial controls on seasonal ice acceleration.

Fracture Propagation to the Base of the Greenland Ice Sheet During Supraglacial Lake Drainage

The rapid (<2 hours) drainage of a large supraglacial lake down 980 meters through to the bed of the Greenland Ice Sheet initiated by water-driven fracture propagation evolving into moulin flow coincided with increased seismicity, transient acceleration, ice-sheet uplift, and horizontal displacement.

Amplified melt and flow of the Greenland ice sheet driven by late-summer cyclonic rainfall

Intense rainfall events significantly affect Alpine and Alaskan glaciers through enhanced melting, ice-flow acceleration and subglacial sediment erosion, yet their impact on the Greenland ice sheet

Winter motion mediates dynamic response of the Greenland Ice Sheet to warmer summers

We present ice velocities from a land‐terminating transect extending >115 km into the western Greenland Ice Sheet during three contrasting melt years (2009–2011) to determine whether enhanced melting

Greenland ice sheet motion coupled with daily melting in late summer

We use ground‐based and satellite observations to detect large diurnal and longer‐period variations in the flow of the Greenland Ice Sheet (GrIS) during late summer that are strongly coupled with

Decadal slowdown of a land-terminating sector of the Greenland Ice Sheet despite warming

It is shown that annual ice motion across an 8,000-km2 land-terminating region of the west GIS margin, extending to 1,100 m above sea level, was 12% slower in 2007–14 compared with 1985–94, despite a 50% increase in surface meltwater production.

Dynamic response of the Greenland ice sheet to recent cooling

It is hypothesized that under thinner ice, increases in basal water pressure offset a larger proportion of the ice overburden pressure, leading to reduced effective pressure and thus greater acceleration when compared to thicker ice further inland, and is strongly correlated with ice thickness.
