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, despite locally warm summers. Repeated airborne laser-altimeter surveys along a 120 km profile in the glacier basin show slow, sporadic thickening between 1991 and 1997, suggesting a small positive mass balance, but since 1997 there has been sustained thinning of several m a -1 within 20 km of the ice…

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

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.

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

Ocean contributes to the melting of the Jakobshavn Glacier front

The Jakobshavn Glacier (JG) in Greenland is one of the most active glaciers in the world. It was close to balance before 1997 but this was followed by a sudden transition to rapid thinning. The

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

Iceberg calving dynamics of Jakobshavn Isbrae, Greenland

Jakobshavn Isbræ, a fast-flowing outlet glacier in West Greenland, began a rapid retreat in the late 1990’s. The glacier has since retreated over 15 km, thinned by tens of meters, and doubled its

Rapid retreat, acceleration and thinning of Glaciar Upsala, Southern Patagonia Icefield, initiated in 2008

Abstract The Patagonia Icefields are characterized by a large number of outlet glaciers calving into lakes and the ocean. In contrast to the recent intensive research activities on tidewater glaciers

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

Changing basal conditions during the speed-up of Jakobshavn Isbræ, Greenland

Abstract. Ice-sheet outlet glaciers can undergo dynamic changes such as the rapid speed-up of Jakobshavn Isbrae following the disintegration of its floating ice tongue. These changes are associated

The Rapid Retreat of Jakobshavns Isbræ, West Greenland: Field Observations of 2005 and Structural Analysis of its Evolution

Jakobshavns Isbræ in West Greenland (terminus at ≈69° 10′ N/50° W), a major outlet glacier of the Greenland Ice Sheet and a continuously fast-moving ice stream, has long been the fastest moving and



Surficial Glaciology of Jakobshavns Isbræ, West Greenland: Part II. Ablation, accumulation and temperature

Abstract Accumulation studies along the lowermost 100 km of Jakobshavns Isbræ show that the local net balance above the equilibrium line (1210 m elevation in 1986) is significantly less than that

Surficial glaciology of Jakobshavns Isbræ, West Greenland: Part I. Surface morphology

Abstract Jakobshavns Isbræ is a large, fast-moving ice stream/outlet glacier in West Greenland which ends at a floating, calving front. It drains about 6.5% of the area of the Greenland ice sheet.

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

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

Greenland Ice Sheet melt extent: 1979–1999

Analysis of melt extent on the Greenland ice sheet is updated to span the time period 1979-1999 and examined along with its spatial and temporal variability using passive microwave satellite data. To

Glaciological and oceanographic evidence of high melt rates beneath Pine Island Glacier, West Antarctica

Abstract Satellite imagery indicates that the floating terminus of Pine Island Glacier has changed little in extent over the past two decades. Data on the velocity and thickness of the glacier reveal

Rapid thinning of parts of the southern greenland ice sheet

These high thinning rates occur at different latitudes and at elevations up to 1500 meters, which suggests that they are caused by increased rates of creep thinning rather than by excessive melting.

Mechanisms of fast flow in Jakobshavns Isbræ, West Greenland: Part I. Measurements of temperature and water level in deep boreholes

Abstract Several holes were drilled to depths of 1500–1630 m along a profile across Jakobshavns Isbræ, 50 km upstream from the calving front. Drilling was by hot water and required approximately 20

Greenland Ice Sheet: High-Elevation Balance and Peripheral Thinning.

Interpolation of results between flight lines indicates a net loss of about 51 cubic kilometers of ice per year from the entire ice sheet, sufficient to raise sea level by 0.13 millimeter per year-approximately 7% of the observed rise.
