LONG-DISTANCE AIRBORNE GLACIAL SOUNDING.

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...

Description
Summary: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)
