Beaked whales are among the cetaceans most frequently associated with sonar-related strandings worldwide.
Since the late 20th century, unusual mass strandings of beaked whales have coincided with naval sonar activity in several regions. Scientific investigations documented gas and fat emboli in stranded individuals, suggesting rapid ascent from deep dives. Cuvier’s beaked whales appear particularly sensitive to mid-frequency active sonar. Studies published in peer-reviewed journals indicate behavioral disruption leading to altered dive patterns. Instead of controlled ascents, whales may surface too quickly, increasing decompression risk. International concern led to mitigation guidelines for naval exercises in known habitats. Regulatory agencies require environmental impact assessments for sonar use. The species became central to discussions about anthropogenic noise. Acoustic disturbance translated into physiological consequence.

The sonar-stranding connection reshaped marine environmental policy debates. Naval forces adopted spatial and temporal restrictions to reduce exposure in sensitive areas. Courts in several countries reviewed compliance under environmental protection laws. Scientific monitoring improved to detect and respond to unusual mortality events. The issue highlighted the intersection of national security and conservation. Acoustic modeling now informs operational planning. Sound emerged as a regulatory variable.
For coastal communities witnessing strandings, the presence of deep-diving whales on beaches created visible evidence of invisible forces. The irony is technological: systems designed for submarine detection affected animals that dive deeper than most submarines. Cuvier’s beaked whales evolved for pressure tolerance, not acoustic shock. Their vulnerability surfaced through human instrumentation. Noise altered survival. Silence gained policy relevance.
