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 ...
The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)
(2014)
Long-finned pilot whales (Globicephala melas) are highly social cetaceans that live in matrilineal groups and acquire their prey during deep foraging dives. We tagged individual pilot whales to record their diving behaviour. ...
Lack of behavioural responses of humpback whales (Megaptera novaeangliae) indicate limited effectiveness of sonar mitigation
(2017)
Exposure to underwater sound can cause permanent hearing loss and other physiological effects in marine animals. To reduce this risk, naval sonars are sometimes gradually increased in intensity at the start of transmission ...
Marine mammals and sonar: dose-response studies, the risk-disturbance hypothesis and the role of exposure context
(2017)
Marine mammals may be negatively affected by anthropogenic noise. Behavioural response studies (BRS) aim to establish a relationship between noise exposure conditions (dose) from a potential stressor and associated behavioural ...
Avoidance responses of minke whales to 1?4 kHz naval sonar
(2017)
Minke whales are difficult to study and little information exists regarding their responses to anthropogenic sound. This study pools data from behavioural response studies off California and Norway. Data are derived from ...
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
(2015)
Behavioral response studies (BRSs) aim to enhance our understanding of the behavior changes made by animals in response to specific exposure levels of different stimuli, often presented in an increasing dosage. Here, we ...
Disturbance-specific social responses in long-finned pilot whales, Globicephala melas
(2016)
Social interactions among animals can influence their response to disturbance. We investigated responses of long-finned pilot whales to killer whale sound playbacks and two anthropogenic sources of disturbance: tagging ...
Modeling Effectiveness of Gradual Increases in Source Level to Mitigate Effects of Sonar on Marine Mammals
(2014)
Ramp-up or soft-start procedures (i.e., gradual increase in the source level) are used to mitigate the effect of sonar sound on marine mammals, although no one to date has tested whether ramp-up procedures are effective ...
High thresholds for avoidance of sonar by free-ranging long-finned pilot whales (Globicephala melas)
(2014)
The potential effects of exposing marine mammals to military sonar is a current concern. Dose–response relationships are useful for predicting potential environmental impacts of specific operations. To reveal behavioral ...
