Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
(2014)
Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ...
Biological significance of sperm whale responses to sonar: Comparison with anti-predator responses
(2016)
A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus ...
Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate and shallow diving toothed whales during exposure to naval sonar.
(2012)
Naval sonar has been accused of causing whale stranding by a mechanism which increases formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased risk of decompression sickness (DCS), ...
Changes in dive behavior during sonar exposure in killer whales, pilot whales and sperm whales.
(2012)
Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ...
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
(2015)
Although northern bottlenose whales were the most heavily hunted beaked whale, we have little information about this species in its remote habitat of the North Atlantic Ocean. Underwater anthropogenic noise and disruption ...
