Researchers studied a number of factors dating back to 1985 for 16 outlet glacier catchments in West Greenland, including a map of bedrock topography to measure ice thickness, and utilized a digital elevation model to distinguish the outlet glaciers.
This suggests a possible positive feedback mechanism whereby retreat of the outlet glacier, in part due to warming of the air and in part due to glacier dynamics, leads to increased dynamic loss of ice upstream.
An outlet glacier located in the northeast part of Greenland has declined 12.
The model will be applied to the Pine Island Glacier (PIG), an important outlet glacier draining a portion of the WAIS, which has been studied extensively and is currently thinning at an increasing rate.
Melt water lubricates the base of glaciers that carry ice from the interior to the sea, causing their movement to accelerate--for instance, the speed of Greenland's largest outlet glacier doubled in just five years.
Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.
In contrast to the situation in Greenland and Svalbard, the largest contributing factor to glacier mass/volume changes in the Canadian Arctic is negative surface mass balance rather than outlet glacier calving (Koerner, 2005; Gardner and Sharp, 2007; Sharp et al.
The findings use new observational techniques to address long-standing questions about subglacial water under Thwaites, a Florida-sized outlet glacier in the Amundsen Sea Embayment considered a key factor in projections of global sea level rise.
Jakobshavn is the largest outlet glacier in Greenland and drains 6.
Morgan was the co-ordinator of the Tunsbergdalsbreen expedition, which surveyed the biggest outlet glacier of the Jostedal icecap in Norway and related the results to environmental change.
Analysis of flow regimes using surface velocities derived from SAR interferometry suggests that the central region of the ice cap is frozen to the bed, while the velocity increases toward the ice cap margin are likely a function of basal lubrication and, near outlet glacier termini, of basal sediment deformation (Burgess et al.
The preferred glacier place name with modern spelling is shown in bold upper-case letters, if an ice cap, and in bold lower-case letters if an outlet glacier or one of the other types.
