RADIO-ECHO SOUNDING ON THE GHULKIN GLACIER IN THE KARAKORAM MOUNTAINS

Together with their British friends, the authors made a field investigation in the Karakoram Mountains in Pakistan for radio-echo sounding on the Ghulkin Glacier during the summer of 1980.Four transverse sections and one longitudinal section including thirty-two measurement points have surveyed on the glacier tongue. The ice-depths at the points have been calculated, and measurement errors analysed on the basis of experimental data.The history and present status of radio-echo sounding are briefly reviewed and appraised in this paper.
