The increasing interest in ice-core analyses has made it apparent that new drills need to be developed for coring in Jim and ice. To close the gap between the range of the SJPRE coring auger and that of the CRREL thermal drill an electromechanical drill has been constructed which will core to 50 m in firn and ice. The drill is sus pended from a cable, and consists of a coring system, a driving system and an antitorque system. The drill was tested successfully in Greenland in 1974, where it was possible to drill to 50 m in a few hours.
