Ice drilling system with near-bottom hot water circulation

Ice drilling systems with near-bottom hot water circulation can be used for many challenging scientific tasks in the study of ice sheets, glaciers, and subglacial environments. These systems melt ice using water jets heated directly at the bottom of the hole, thus eliminating the use of long heavy hoses and surface pumps. To investigate the influence of the drill tip shape and nozzle diameter on the drilling process, a simplified laboratory...
