TLDR
Evidence of acute and chronic tissue damage in stranded cetaceans that results from the formation in vivo of gas bubbles is presented, challenging the view that these mammals do not suffer decompression sickness.Abstract:
Was sonar responsible for a spate of whale deaths after an Atlantic military exercise? There are spatial and temporal links between some mass strandings of cetaceans — predominantly beaked whales — and the deployment of military sonar1,2,3. 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.read more

Responses of cetaceans to anthropogenic noise
TL;DR: In this paper, a review of the effects of anthropogenic noise on cetaceans has been published and their ability to document response(s), or the lack thereof, has improved.
Journal ArticleDOI
Extreme diving of beaked whales
TL;DR: Using current models of breath-hold diving, it is inferred that beaked whales' natural diving behaviour is inconsistent with known problems of acute nitrogen supersaturation and embolism, and possible decompression problems are more likely to result from an abnormal behavioural response to sonar.

Intramembrane cavitation as a unifying mechanism for ultrasound-induced bioeffects.
TL;DR: The hypothesis that ultrasonically induced bilayer membrane motion, which does not require preexistence of air voids in the tissue, may account for a variety of bioeffects and could elucidate mechanisms of ultrasound interaction with biological tissue that are currently not fully understood is supported.
Journal ArticleDOI
Beaked whales echolocate on prey
TL;DR: Beaked whales (Cetacea: Ziphiidea) of the genera Ziphius and Mesoplodon are so difficult to study that they are mostly known from strandings.
Journal ArticleDOI
The impacts of anthropogenic ocean noise on cetaceans and implications for management
TL;DR: Ocean noise pollution is of special concern for cetaceans, as they are highly dependent on sound as their principal sense, and the potential area impacted can be thousands of square kilometres or more.

Does acoustic testing strand whales
TL;DR: It is found that a recent stranding of Cuvier's beaked whale coincided closely in time and location with military tests of an acoustic system for submarine detection being carried out by the North Atlantic Treaty Organization (NATO).

Dolphin lung collapse and intramuscular circulation during free diving: evidence from nitrogen washout
Sam H. Ridgway,Red Howard +1 more
TL;DR: The bottle-nosed dolphin is not protected by lung collapse from the decompression hazards of dives to depths shallower than 70 meters, so intramuscular nitrogen tensions after a schedule of repetitive ocean dives suggest.

TL;DR: This book discusses the physiology and medicine of diving, and the long term effects of diving on the Lung, Bones, and Central Nervous System.
