“…If all protocols are identical, different investigators commonly define a glacier perimeter differently. For example, some investigators may include a small tributary ice patch while others may exclude it (e.g., Jackson and Fountain, 2007). Combining these two data sets without regard to understanding differing assumptions and techniques, particularly as sequential time series, leads to erroneous results.…”

“…In addition, subglacial cavitation and the formation of proglacial lakes (Frey and others, 2010) may further increase the rate of terminus retreat. One important feedback effect reducing glacier melt is the observed increasing debris coverage of an Alpine glacier tongue due to its retreat (Huss and others, 2007;Jackson and Fountain, 2007;Kellerer-Pirklbauer and others, 2008). Supraglacial debris is known to significantly reduce the melting of bare ice, due to its insulating properties (e.g.…”

Modelling the retreat of Grosser Aletschgletscher, Switzerland, in a changing climate

For more than a century Alpine glaciers have been retreating dramatically, and they are expected to shrink even more quickly over the coming decades. This study addresses the future evolution of Grosser Aletschgletscher, Switzerland, the largest glacier in the European Alps. A three-dimensional combined surface mass-balance and glacier dynamics model was applied. The ice flow was described with the full Stokes equations. The glacier surface evolution was obtained by solving a transport equation for the volume of fluid. Daily surface melt and accumulation were calculated on the basis of climate data. The combined model was validated against several types of measurements made throughout the 20th century. For future climate change, scenarios based on regional climate models in the ENSEMBLES project were used. According to the median climatic evolution, Aletschgletscher was expected to lose 90% of its ice volume by the end of 2100. Even when the model was driven using current climate conditions (the past two decades) the glacier tongue experienced a considerable retreat of 6 km, indicating its strong disequilibrium with the present climate. By including a model for the evolution of supraglacial debris and its effect in reducing glacier melt, we show that this factor can significantly slow future glacier retreat.

“…Between 1901 and 2001, Eliot Glacier lost 775 m in length (Lillquist and Walker, 2006). Presently, Eliot Glacier is less than 1Ð6 km 2 , 3Ð6 km long, and 800 m at its greatest width (Jackson, 2007) (Figure 1). The glacier response observed in the Cascades is consistent with worldwide loss of mountain glaciers (Dyurgerov and Meier, 2000).…”
