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 has not been assessed. Here we present measurements of ice velocity, subglacial water pressure and meteorological variables from the western margin of the Greenland ice sheet during a week of warm, wet cyclonic weather in late August and early September 2011. We find that extreme surface runoff from… 

Greenland Ice Sheet late-season melt: investigating multiscale drivers of K-transect events

Abstract. One consequence of recent Arctic warming is an increased occurrence and longer seasonality of above-freezing air temperature episodes. There is significant disagreement in the literature

Increased Greenland melt triggered by large-scale, year-round precipitation events

Abstract. Surface melting is a major driver of Greenland's mass loss. Yet, the mechanisms that trigger melt are still insufficiently understood because seasonally-based studies blend processes

Increased Greenland melt triggered by large-scale, year-round cyclonic moisture intrusions

Abstract. Surface melting is a major driver of Greenland's mass loss. Yet, the mechanisms that trigger melt are still insufficiently understood because seasonally based studies blend processes

Investigating the local-scale influence of sea ice on Greenland surface melt

Abstract. Rapid decline in Arctic sea ice cover in the 21st century may have wide-reaching effects on the Arctic climate system, including the Greenland ice sheet mass balance. Here, we investigate

The Influence of Hydrology on the Dynamics of Land-Terminating Sectors of the Greenland Ice Sheet

Coupling between runoff, hydrology, basal motion, and mass loss (“hydrology-dynamics”) is a critical component of the Greenland Ice Sheet system. Despite considerable research effort, the mechanisms

Greenland Ice Sheet Rainfall, Heat and Albedo Feedback Impacts From the Mid‐August 2021 Atmospheric River

Rainfall at the Greenland ice sheet Summit 14 August 2021, was delivered by an atmospheric river (AR). Extreme surface ablation expanded the all‐Greenland bare ice area to near‐record‐high with

Seasonal Evolution of the Subglacial Hydrologic System Modified by Supraglacial Lake Drainage in Western Greenland

The impact of summer surface melt on Greenland Ice Sheet dynamics is modulated by the state of the subglacial hydrologic system. Studies of ice motion indicate that efficiency of the subglacial

Impact of runoff temporal distribution on ice dynamics

Abstract. Records of meltwater production at the surface of the Greenland ice sheet have been recorded with a surprisingly high recurrence over the last decades. Those longer and/or more intense melt

Subglacial lakes and their changing role in a warming climate

Subglacial lakes are repositories of ancient climate conditions, provide habitats for life and modulate ice flow, basal hydrology, biogeochemical fluxes and geomorphic activity. In this Review, we

Seismic evidence for complex sedimentary control of Greenland Ice Sheet flow

Observations from amplitude-versus-angle seismic data are presented as the first observational test of the sedimentary control of ice sheet flow hypothesis and confirm the alternative hypothesis that melt season acceleration of ice flow due to weakening of subglacial sediments does not currently outweigh winter slowdown forced by self-regulation.



Greenland ice sheet motion insensitive to exceptional meltwater forcing

It is suggested that annual motion of land-terminating margins of the ice sheet, and thus the projected dynamic contribution of these margins to sea level rise, is insensitive to melt volumes commensurate with temperature projections for 2100.

Links between acceleration, melting, and supraglacial lake drainage of the western Greenland Ice Sheet

[1] The impact of increasing summer melt on the dynamics and stability of the Greenland Ice Sheet is not fully understood. Mounting evidence suggests seasonal evolution of subglacial drainage

Seasonal evolution of subglacial drainage and acceleration in a Greenland outlet glacier

An acceleration of ice-mass loss has been observed near the margin of the Greenland ice sheet, partly as a result of faster ice motion. Observations by GPS receivers reveal high seasonal variability

Seasonal Speedup Along the Western Flank of the Greenland Ice Sheet

A data set is assembled that provides a synoptic-scale view, spanning ice-sheet to outlet-glacier flow, that reveals summer speedups on the ice sheet consistent with, but somewhat larger than, earlier observations.

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

Partitioning of melt energy and meltwater fluxes in the ablation zone of the west Greenland ice sheet

Abstract. We present four years (August 2003–August 2007) of surface mass balance data from the ablation zone of the west Greenland ice sheet along the 67° N latitude circle. Sonic height rangers and

Surface Melt-Induced Acceleration of Greenland Ice-Sheet Flow

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.

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.

Future projections of the Greenland ice sheet energy balance driving the surface melt

Abstract. In this study, simulations at 25 km resolution are performed over the Greenland ice sheet (GrIS) throughout the 20th and 21st centuries, using the regional climate model MAR forced by four

Sensitive response of the Greenland Ice Sheet to surface melt drainage over a soft bed.

It is proposed that sedimentary control on ice flow is a viable alternative to existing models of evolving hydrological systems, and a strong link between the annual flow stability, and the frequency of high meltwater discharge events is found.
