Abstract

One of the most effective ways to probe an underwater environment for purposes of navigation, obstacle avoidance, and prey detection is by sonar (sound navigation and ranging). Many odontocete emit sounds and analyze returning echoes to detect and recognize objects underwater. Prior to 1979, most of the experiments were performed in tanks, using mm sized targets and short ranges (see Murchison, 1980a). This review will consider sonar detection and discrimination experiments performed in the open waters of Kaneohe Bay, Oahu, Hawaii with the Atlantic bottlenose dolphin (Tursiops truncatus) and beluga whale (Delphinapterus leucas).
