A review of the use of radio-echo sounding in glaciology

Radio-echo sounding (RES), or radar, is an established geophysical technique that has been, and continues to be, applied to investigate a variety of ice-mass properties. This review presents the physical theory and principles of radio-glaciology, and describes the various types of radar equipment commonly used, including modern, ground-penetrating radar (GPR) systems. The range of glaciological applications these systems have been used to investigate is summarized, along with promising avenues of current and future research.
