Abstract : A 90-km sound-transmission test on the continental slope of the Arctic Ocean north of the Canadian Archipelago is described. Spectrum levels of sounds from 1-lb explosive charges vs distance are presented for frequencies in the range 12 cps to 16 kcps. Results confirm the low-pass filtering effect of the ice canopy and assist in the determination of transmission losses. (Author)
