Abstract: Abstract Drilling to till and bedrock of ice sheets and glaciers offers unique opportunities for examining processes acting at the bed. Samples of basal and subglacial material contain important paleo-climatic and paleo-environmental records and provide a unique habitat for life, give significant information on sediment deformation beneath glaciers and its coupling to the subglacial hydraulic system, subglacial geology, and tectonics. Retrieving bedrock samples under ice sheets and glaciers is a very difficult task. Drilling operations are comp...
