Although considerable progress has been made in recent years in understanding the behaviour of debris-covered glaciers, many fundamental processes on, within and surrounding this glacier type remain ill-understood. As debris-covered glacier processes cross the fields of glaciology, geology, geomorphology, hydrology and meteorology in unique ways, a wide range of expertise is required to bridge our knowledge gaps.
The session we organized for the AGU Fall Meeting in California in December 2019, co-organized by the Cryopshere and Earth and Planetary Surface Processes focus groups, aimed to improve process understanding related to debris-type glaciers and brought together expertise from quite different fields, e.g.:
Leif Anderson (GFZ Potsdam, Germany) - Ice dynamical controls on the rapid thinning of debris-covered glaciers (Invited)
James Ferguson (U. Zurich, Switzerland) - Historical Reconstruction and Numerical Modelling of Zmuttgletscher, Swiss Alps, Since the Little Ice Age
Dawa Tshering Sherpa (Kathmandu U., Nepal) - Spatial Distribution of Debris Thickness from Remote-Sensing and Modeling in Marshyangdi River Basin, Nepal
Eric Petersen (U. Arizona, USA) - The Transition from Alpine Glacier to Rock Glacier: A Case Study at Sulphur Creek, Wyoming
Alessandro Cicoira (U. Zurich, Switzerland) - Resolving the influence of climatic forcing on rock glacier dynamics: a numerical modelling approach
Morgan Monz (U. of Minnesota Twin Cities, USA) - Crystallographic preferred orientation in warm, coarse-grained ice: a case study, Storglaciären, Sweden
Jaakko Putkonen (U. North Dakota, USA) - Ancient Ice Preserved Under A Meter-Thick Layer Of Debris; Ong Valley, Transantarctic Mountains, Antarctica
Emilio Mateo (Ohio State U., USA) - Evaluation of inter-annual to decadal changes in tropical Andean stream chemistry below debris-covered glaciers
Pascal Buri (U. Alaska Fairbanks, USA) - From the Equator to the Pole: How Latitude Affects Incident Shortwave Radiation on Supraglacial Ice Cliffs
Thanks to the co-conveners of this session, Bob Anderson, Caroline Aubry-Wake and Jakob Steiner, for making this session happen, and to all the participants at our AGU session for great posters and exciting discussions across fields!
