Was sonar responsible for a spate of whale deaths after an Atlantic military exercise?

Abstract

There are spatial and temporal links between some mass strandings of cetaceans — predominantly beaked whales — and the deployment of military sonar1,2,[3](/articles/425575a#ref-CR3 "US Dept Commerce & US Navy Joint Interim Report: Bahamas Marine Mammal Stranding Event of 15–16 March 2000 http://www.nmfs.noaa.gov/prot_res/overview/Interim_Bahamas_Report.pdf

             (2001)."). Here we present evidence of acute and chronic tissue damage in stranded cetaceans that results from the formation _in vivo_ of gas bubbles, challenging the view that these mammals do not suffer decompression sickness. The incidence of such cases during a naval sonar exercise indicates that acoustic factors could be important in the aetiology of bubble-related disease and may call for further environmental regulation of such activity.
