Conditions on the Bedrock and Surface of the Vavilov Ice Cap (Severnaya Zemlya) during Its Surge according to Airborne Radar Data
摘要
Abstract
The data of measurements of the delay time and amplitudes of radio reflections from the bedrock of the Vavilov Ice Cap, obtained during the period of rapid movement of its western part were used to evaluate the power reflection coefficient from the bedrock, which correlate with the high speeds (more than 1000 m/year) of glacier movement in the area that has advanced onto the shallow water area.
