PRELIMINARY REPORTS ON THE USE OF ELECTROMETRY IN STUDYING THE MOVEMENT OF GLACIERS
The first measurements of the surface rate of movement of glaciers were made 200 years ago. Extensive data on the movement of glaciers have now been collected on a planetary scale, but in the overwhelming majority of cases it characterizes with sufficient accuracy only the surface rates for differen...
