Description :
To improve the understanding of the interactions between hydrology and dynamics in mostly cold glaciers (in which water flow is limited by thermal regime), the AA. analyse short-term (every 2 days) variations in glacier flow in the ablation zone of polythermal John Evans Glacier, High Arctic Canada. They monitor the spatial and temporal propagation of high-velocity events, and examine their impacts upon supraglacial drainage processes and evolving subglacial drainage system structure. They assess the extent to which the observed short-term variations in dynamics may impact on long-term mass balance.
