Description :
The studies were carried out in the summer 1998. The article contains an attempt to evaluate the influence of morainic material placed on the glacier's surface and in the adjacent layer on the ablation's degree. The experiments with ablational duvets attested to the importance of the type of surface on which a duvet is placed. In the case of clean ice, the ablation from an ice screw is more limited than the growth of the ice knob by approximately 14-22 %. But in the case of dirty ice the ablation from the screw equal the growth of the ice knob under the duvet. The effect of selective melting is only observable where an ablation layer exist. - (BJ)
