C09 - DEBRIS COVERED GLACIERS
Conveners: Francesca Pellicciotti, Duncan Quincey, Patrick Wagnon
Debris-covered glaciers, mantled in a layer of continuous or discontinuous debris over all or part of their tongues, are common in many mountain ranges of the world. Debris alters the surface energy and mass balance of glaciers and thus the way these glaciers react to climate. The past decade has seen a dramatic advance in our understanding of their surface processes, mass balance, hydrology, dynamics and long-term evolution. However, many open questions remain. Also modelling debris-covered glaciers remains challenging. This symposium aims to bring together new research results from a variety of different approaches, including numerical modelling, observations and remote sensing, to understand debris-covered glaciers, their processes and main controls. In particular, we invite contributions that include, but are not limited to: i) the formation, characteristics and movement of supraglacial debris; ii) studies of debris-covered glacier energy balance and mass balance, with special emphasis on surface processes such as the formation of supraglacial ponds and cliffs; iii) their hydrology, including englacial and subglacial characteristics; iv) debris-covered glaciers dynamics; v) remote-sensing observations and numerical modelling of debris-covered glaciers and prediction of their changes in response to climate; vi) long term evolution of debris-covered glaciers, reconstructions of former glaciers and their climatic interpretations; vii) the development of hazards associated with debris-covered glaciers such as glacier lake outburst floods or debris flows.
