Abstract : Experiments during the summer of 1966 established the feasibility of using airborne 30 MHz vertical incidence radar for sounding the thickness of polar ice sheets over long-range traverses. Four flights across Greenland each averaging 8 hours of flight time and approximately 2400 km. in length were continuously sounded. An automated data acquisition system, employed for the first time, was primarily responsible for the increased long-range capability. The principal limitations have been attributed to problems associated with navigating the polar regions. (Author)
