Abstract:

The backscattering strengths under Arctic sea ice for octave bands between 12 cps and 4 kcsec were measured, using explosive sound sources. The measurements were made from a camp established in April 1962 on broken and pressure-packed one-year ice over the Canada Deep. For grazing angles between 5 degrees and 14 degrees, results show a dependence of scattering strengths both on grazing angle and on frequency. The dependence on grazing angle is small in frequencies above the 0.5- to 1-kcsec band and large in the 12- to 25-cps band. Author
