Estimation of Basal Heat Flux Over Ice-Covered Areas From Radio Echo-Sounding

Abstract Two fundamental boundary conditions for basal ice may be recognized by radio echo-sounding: ice–rock and ice–water interfaces. The latter is identified on the basis of horizontal echoes displaying slow fading, high persistent returned power, and with a reflection coefficient lying between –...
