Influence of snowpack internal structure on snow metamorphism and melting intensity on Hansbreen, Svalbard
Abstract This paper presents a detailed study of melting processes conducted on Hansbreen – a tidewater glacier terminating in the Hornsund fjord, Spitsbergen. The fieldwork was carried out from April to July 2010. The study included observations of meltwater distribution within snow profiles in dif...

The time necessary for meltwater to percolate through the entire snowpack in both, the ablation zone and the equilibrium line zone amounted to c. 12 days, despite a much greater snow depth at the upper site. An elongated retention of meltwater in the lower part of the glacier was caused by a higher amount of icy layers ( ice formations and melt-freeze crusts ), resulting from winter thaws, which delayed water penetration.
