Abstract
The specificity of ray trajectories in the presence of a benthic front, which is the boundary between the Antarctic deep and bottom waters, has been considered. Deep-water “noncanonical” caustic surfaces confined to the front have been found. The ability to reconstruct a sound velocity profile in the benthic frontal zone has been evaluated using methods of ray tomography in the ocean. A possible reconstruction of the profile using a horizontal displacement of the receiving antenna or transmitter at relatively small depths has been shown.
