Spatio-Temporal Restrictions as Best Practice Precautionary Response to Ocean Noise

Despite the increasing reports of atypical cetacean strandings and subsequent deaths that have been associated with military sonar, the mechanism of injury remains unknown. While this may remain the case for some time, there is emerging evidence regarding the nature of the damage and the sound levels that induce it. It is increasingly apparent that tissue damage and strandings may be induced at received sound levels that are lower than had previously been anticipated. In particular, at levels lower than those that can induce auditory damage, and, most significantly, lower than those currently being used as an acceptable level for management guidance.
