Abstract : In June and July of 1964, extensive field trials of radar ice sounding equipment were held on the ice sheet in northwest Greenland. The results, in the form of profiles over 350 km of trail, made from seismic depth measurements along the Tuto-Century trail and Project 42 trails provide a good representation of surface and subsurface topography. A continuous trace of the ice/bedrock interface was obtained for over 97% of the route traveled, through ice up to 1400 meters thick. The film record obtained by the Scott Polar Research Institute, as a result of providing the Scott Polar Research radar set with continuously moving photographic film to record echo traces, shows a richness of detail (internal structure of the ice sheet) not portrayed by the manual plot. A sample of this film is given. References are made to project work of previous seasons. (Author)
