Morard sebastien.morard@unifr.ch M. Bochud R. Delaloye Geography Unit, Department of Geosciences, University of Fribourg, Fribourg, Switzerland Geology Unit, Department of Geosciences, University of Fribourg, Fribourg, Switzerland Spéléo-Club des Préalpes Fribourgeoises (SCPF), Fribourg, Switzerland The Gouffre des Diablotins is a deep cave system located in the Swiss Prealps. In 1991, the entrance zone of the cave was almost free of ice. Nevertheless ice volume sharply increased in 1994, plugging almost totally the gallery from the lower entrance. The ice cave have also experience flooded period between 1996 and 2007, and very heterogeneous ice surface morphology and textures have formed. Continuous cave climate measurements initiated in 2009 showed the predominant role of winter atmospheric air conditions to drive both the efficiency of chimney-effect circulation and seasonal modifications of the ice mass. Main part of the ice loss is currently due to sublimation in wintertime. Arenson, L. U. and Sego, D.
