Abstract
We have investigated drift-ice maps plotted from aerial photographs and studied their correspondence with the radar picture. Such things as open water surfaces, separate ice-cakes and boundaries where the thickness abruptly changes show up well in the PPI display. Only from uniformly even young ice was there almost no back-scatter, and care was required to distinguish such areas from open water. The brightness characteristics of the cathode ray tube are such that differences in the intensity of echoes do not show up very markedly in the PPI display; this decontrasting effect, however, makes the attenuated intensities of the reflections from a complex ice-field more easily visible.
