Abstract:
Localised areas (10-10 cubic m) of basal friction ('sticky spots') are known to be a significant control on ice stream behaviour and shutdown and hence, overall ice sheet stability. Although of critical importance, they are difficult to observe and characterise beneath contemporary ice streams. We will overcome this problem by using Earth Observation and fieldwork to map and characterise their distribution on three exposed former ice stream beds in Arctic Canada. This will provide the first physical description of the nature and occurrence of sticky spots including geologic, topographic and geotechnical data on their dimensions, geomorphology and distribution. Incorporated into a GIS, this data will be used to test existing numerical models of ice stream basal mechanics and shutdown in order to examine sticky spot influence on ice stream functioning.
