Tagging and Playback Studies to Toothed Whales
While atypical mass strandings of beaked whales have been linked to naval exercises using mid-frequency sonar, the causal chain of events from sound exposure to stranding has not been elucidated. We now know that beaked whales react strongly to sonar, killer whale calls, and bandlimited noise by cea...
