Observations over past decades show a sudden switch of Jakobshavn Isbrae—a large outlet glacier feeding a deep-ocean fjord on Greenland’s west coast—from slow thickening to rapid thinning in 1997. This switch is associated with a doubling in glacier velocity. Hydrographic data show a concurrent sudden increase in subsurface ocean temperatures along the entire west coast of Greenland, suggesting that the changes in Jakobshavn Isbrae were triggered by the arrival of relatively warm water… 

Interruption of two decades of Jakobshavn Isbrae acceleration and thinning as regional ocean cools

Jakobshavn Isbrae has been the single largest source of mass loss from the Greenland Ice Sheet over the last 20 years. During that time, it has been retreating, accelerating and thinning. Here we use

Rapid circulation of warm subtropical waters in a major glacial fjord in East Greenland

The recent rapid increase in mass loss from the Greenland ice sheet is primarily attributed to an acceleration of outlet glaciers. Oceanographic data obtained in summer 2008 show that subtropical

Rapid response of Helheim Glacier in Greenland to climate variability over the past century

During the early 2000s the Greenland Ice Sheet experienced the largest ice-mass loss of the instrumental record 1 , largely as a result of the acceleration, thinning and retreat of large outlet

Glacier dynamics over the last quarter of a century at Helheim, Kangerdlugssuaq and 14 other major Greenland outlet glaciers

The Greenland ice sheet is experiencing increas- ing rates of mass loss, the majority of which results from changes in discharge from tidewater glaciers. Both atmo- spheric and ocean drivers have

A Decade of Variability on Jakobshavn Isbrae: Ocean Temperatures Pace Speed Through Influence on Mélange Rigidity

Abstract. The speed of Greenland’s fastest glacier, Jakobshavn Isbrae, has varied substantially since its speedup in the late 1990s. Here we present observations of surface velocity, mélange

Glacier dynamics near the calving front of Bowdoin Glacier, northwestern Greenland

To better understand recent rapid recession of marine-terminating glaciers in Greenland, we performed satellite and field observations near the calving front of Bowdoin Glacier, a 3 km wide outlet

A Decade of Variability on Jakobshavn Isbrae: Ocean Temperatures Pace Speed Through Influence on Mélange Rigidity.

The results suggest that the ocean's dominant influence on Jakobshavn Isbrae is through its effect on winter mélange rigidity, rather than summer submarine melting.

Rapid submarine melting of the calving faces of West Greenland glaciers

Widespread glacier acceleration has been observed in Greenland in the past few years. Oceanographic observations taken in summer 2008 show that ocean waters melted a substantial fraction of ice along

Quantifying velocity response to ocean tides and calving near the terminus of Jakobshavn Isbræ, Greenland

Dynamic changes on Greenland outlet glaciers are a primary driver for increases in icesheet mass loss and its contribution to sea-level rise. One dramatic example of such change has been observed at

Outlet glacier response to forcing over hourly to interannual timescales, Jakobshavn Isbræ, Greenland

Abstract The loss of the floating ice tongue on Jakobshavn Isbrӕ, Greenland, in the early 2000s has been concurrent with a pattern of thinning, retreat and acceleration leading to enhanced



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,

Recent changes on Greenland outlet glaciers

Abstract Aircraft laser-altimeter surveys during the 1990s showed near-coastal parts of the Greenland ice sheet to be thinning; despite slow thickening at higher elevations, the ice sheet lost mass

Large fluctuations in speed on Greenland's Jakobshavn Isbræ glacier

Remote sensing data is used to measure the velocity of Jakobshavn Isbræ to indicate that fast-flowing glaciers can significantly alter ice discharge at sub-decadal timescales, with at least a potential to respond rapidly to a changing climate.

North Atlantic Subpolar Gyre Warming - Impacts on Greenland Offshore Waters

Sea-surface temperature anomalies in the North Atlantic Subpolar Gyre indicate cold conditions in the 1980s and warming from the mid-1990s onwards, with maximum temperatures observed during October

Intermittent thinning of Jakobshavn Isbræ, West Greenland, since the Little Ice Age

Abstract Rapid thinning and velocity increase on major Greenland outlet glaciers during the last two decades may indicate that these glaciers became unstable as a consequence of the Jakobshavn effect

Thermohaline changes in the Irminger Sea

The Inninger Sea is part of the Subpolar Gyre in the northwestern North Atlantic and plays a central role in the large-scale thennohaline overturning of Atlantic Water which is believed to influence

Decline of Subpolar North Atlantic Circulation During the 1990s

Analysis of the local surface forcing suggests that the 1990s buoyancy forcing has a dynamic effect consistent with altimetric and hydrographic observations: A weak thermohaline forcing allows the decay of the domed structure of subpolar isopycnals and weakening of circulation.

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.

Seismic-reflection evidence for a deep subglacial trough beneath Jakobshavns Isbræ, West Greenland

Abstract Seismic-reflection methods were used to determine the ice thickness and basal topography of Jakobshavns Isbræ, a large, fast-moving ice stream/outlet glacier in West Greenland. A method of

Thickening of Jakobshavns Isbræ, West Greenland, measured by airborne laser altimetry

NASA flights over southern Greenland in 1991, 1992 and 1993, using a scanning laser altimeter with Global Positioning System (GPS) navigation, have demonstrated a capability to measure ice-surface
