520	3 |a"Sound-paths under sea-ice appear to be more stable than those in ice-free seas. High stability may permit a certain degree of reverberation cancellation to be utilized in fixed location echo ranging. The results of a preliminary experiment which measured the stability of direct sound-paths under the sea-ice of M'Clure Strait in the Canadian Arctic Archipelago are described."--Abstract (page 1).
