It has been widely hypothesized that a warmer climate in Greenland would increase the volume of lubricating surface meltwater reaching the ice-bedrock interface, accelerating ice flow and increasing mass loss. We have assembled a data set that provides a synoptic-scale view, spanning ice-sheet to outlet-glacier flow, with which to evaluate this hypothesis. On the ice sheet, these data reveal summer speedups (50 to 100%) consistent with, but somewhat larger than, earlier observations. The… 

Influence of ice-sheet geometry and supraglacial lakes on seasonal ice-flow variability

Supraglacial lakes play an important role in establishing hydrological connections that allow lubricating seasonal meltwater to reach the base of the Greenland Ice Sheet. Here we use new surface

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.

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

Melt-induced speed-up of Greenland ice sheet offset by efficient subglacial drainage

Satellite observations of ice motion recorded in a land-terminating sector of southwest Greenland are used to investigate the manner in which ice flow develops during years of markedly different melting, and a model of ice-sheet flow that captures switching between cavity and channel drainage modes is consistent with the run-off threshold, fast-flow periods, and later-summer speeds.

Investigating the influence of surface meltwater on the ice dynamics of the Greenland Ice Sheet

This thesis explains the annual ice velocity cycle of the Sermeq (Glacier) Avannarleq flowline, in West Greenland, using a longitudinally coupled 2D (vertical cross-section) ice flow model coupled to

Ice flow dynamics and surface meltwater flux at a land-terminating sector of the Greenland ice sheet

Abstract We present satellite-derived velocity patterns for the two contrasting melt seasons of 2009–10 across Russell Glacier catchment, a western, land-terminating sector of the Greenland ice sheet

Recharge of a subglacial lake by surface meltwater in northeast Greenland

Digital elevation models from stereo satellite imagery and airborne measurements are used to resolve elevation changes during the evolution of the surface and basal hydrologic systems at the Flade Isblink ice cap in northeast Greenland to show that surface meltwater can be trapped and stored at the bed of an ice sheet.

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

Limits to future expansion of surface‐melt‐enhanced ice flow into the interior of western Greenland

Moulins are important conduits for surface meltwater to reach the bed of the Greenland Ice Sheet. It has been proposed that in a warming climate, newly formed moulins associated with the inland



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.

Rapid retreat and acceleration of Helheim Glacier, east Greenland

A significant amount of the measured coastal thinning of the Greenland ice sheet may be due to recent acceleration of outlet glaciers. Using remote sensing, we measured two major periods of speedup

Jakobshavn Glacier, west Greenland: 30 years of spaceborne observations

Early 1960's reconnaissance satellite images are compared to more recent image and map data in an interannual and seasonal study of West Central Greenland margin fluctuations. From 1962 to 1992, ice

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.

Greenland Ice Sheet Surface Mass Balance Variability (1988–2004) from Calibrated Polar MM5 Output*

Regional climate model runs using the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesocale Model modified for use in polar regions (Polar MM5), calibrated

Rapid and synchronous ice‐dynamic changes in East Greenland

Two major outlet glaciers in East Greenland have suddenly begun to accelerate and retreat. The speeds of Kangerdlugssuaq and Helheim remained steady during the 1990s despite progressive and

Investigation of surface melting and dynamic thinning on Jakobshavn Isbrae, Greenland

Jakobshavn Isbrae is the most active glacier in Greenland, with an annual discharge of about 30 km 3 of ice, and it is one of the few recently surveyed glaciers to thicken between 1993 and 1998,

Rapid Changes in Ice Discharge from Greenland Outlet Glaciers

Using satellite-derived surface elevation and velocity data, major short-term variations in recent ice discharge and mass loss at two of Greenland's largest outlet glaciers are found, pointing to an alternative source of loss and the need for high-resolution observations of outlet dynamics and glacier geometry for sea-level rise predictions.

Jakobshavns Isbræ, West Greenland: seasonal variations in velocity -- or lack thereof

Abstract The lower 80 km of the fast-moving Jakobshavns Isbræ, West Greenland, is subject to significant melting during the summer season. The melt water drains into large supraglacial rivers which
