  • Abstract
    Acoustic data were collected in an attempt to determine the feasibility of through-ice tracking. Signals received at the upper surface of the ice were compared with the in-water acoustic pulses and changes in the pulse character were examined to assess the nature and extent of ice-caused perturbations. The results were then compared with a theory relating acoustic propagation at the water-ice interface to aspect angles.
