Abstract: Sound knowledge of the ice volume and ice-thickness distribution of a glacier is essential for many glaciological applications. However, direct measurements of ice thickness are laborious, not feasible everywhere and necessarily restricted to a small number of glaciers. In this paper, we present a method to estimate the ice-thickness distribution and the total ice volume of alpine glaciers. This method is based on glacier mass turnover and principles of ice-flow mechanics. The required input data are the glaci… Show more

“…Whereas we take into account positive feedbacks of increasing fraction of precipitation occurring in liquid form, and the prolongation of the melting season, additional positive backcoupling mechanisms as darker glacier tongues due to dust deposition (Oerlemans et al, 2009) and lakes forming in front of glacier termini, e.g. at Rhonegletscher (Farinotti et al, 2009a), are not considered. We do not account for feedbacks that locally reduce ice melt rates as well, such as increasingly debris-covered glacier tongues (Kellerer-Pirklbauer et al, 2008), and decreased direct radiation as the glacier lowers into deeply incised and shaded valley bottoms.…”

“…Ice thickness was measured using radio-echo sounding in 2003 and 2008 on Rhonegletscher, and in 2007 on Silvrettagletscher (Farinotti et al, 2009a). Bedrock maps were generated using an interpolation scheme accounting for the principles of ice flow dynamics (Farinotti et al, 2009a) which is applied between radio-echo sounding profiles.…”

“…This issue should be resolved by extending the dataset by depth-sounding or other means (Farinotti et al, 2009;Fischer, 2009) of estimating glacier volume for many more glaciers, especially in regions with high topographic relief. We note that changes in sub-glacial hydrology or in thermal conditions at the glacier bed may also have an effect on γ .…”
