Avoidance responses of minke whales to 1?4 kHz naval sonar
Kvadsheim, Petter Helgevold; DeRuiter, Stacy; Sivle, Lise Doksæter; Goldbogen, Jeremy; Hansen, Rune Roland; Miller, Patrick J.O.; Lam, Frans-Peter A.; Calambokidis, John; Friedlaender, Ari; Visser, Fleur; Tyack, Peter L.; Kleivane, Lars; Southall, Brandon (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 ... -
Changes in dive behavior during sonar exposure in killer whales, pilot whales and sperm whales.
Doksæter, Lise Henriksen; Kvadsheim, Petter Helgevold; Fahlman, Andreas; Lam, Frans-Peter A.; Tyack, Peter L.; Miller, Patrick J.O. (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), ... -
Disturbance-specific social responses in long-finned pilot whales, Globicephala melas
Visser, Fleur; Curé, Charlotte; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Tyack, Peter L.; Miller, Patrick J.O. (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 ... -
Dose response severity functions for acoustic disturbance in cetaceans using recurrent event survival analysis
Harris, Catriona M.; Sadykova, Dinara; DeRuiter, Stacy; Tyack, Peter L.; Miller, Patrick J.O.; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Thomas, Len (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 ... -
Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales
Miller, Patrick J.O.; Antunes, Ricardo; Wensveen, Paul; Samarra, Filipa I. P.; Alves, Ana Catarina; Tyack, Peter L.; Kvadsheim, Petter Helgevold; Kleivane, Lars; Lam, Frans-Peter A.; Ainslie, Michael A; Thomas, Len (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 ... -
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.
Kvadsheim, Petter Helgevold; Miller, Patrick J.O.; Tyack, Peter L.; Doksæter, Lise Henriksen; Lam, Frans-Peter A.; Fahlman, Andreas (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), ... -
First indications that northern bottlenose whales are sensitive to behavioural disturbance from anthropogenic noise
Miller, Patrick J.O.; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Tyack, Peter L.; Curé, Charlotte; DeRuiter, Stacy; Kleivane, Lars; Sivle, Lise Doksæter; van IJsselmuide, Sander; Visser, Fleur; Wensveen, Paul J.; von Benda-Beckmann, Alexander M.; López, L Martin; Narazaki, T; Hooker, S. (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 ... -
High thresholds for avoidance of sonar by free-ranging long-finned pilot whales (Globicephala melas)
Antunes, Ricardo; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Tyack, Peter L.; Thomas, Len; Wensveen, Paul J.; Miller, Patrick James O'Malley (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 ... -
How man-made interference might cause gas bubble emboli in deep diving whales
Fahlman, Andreas; Tyack, Peter L.; Miller, Patrick J.O.; Kvadsheim, Petter Helgevold (2014)Recent cetacean mass strandings in close temporal and spatial association with sonar activity has raised the concern that anthropogenic sound may harm breath-hold diving marine mammals. Necropsy results of the stranded ... -
Lack of behavioural responses of humpback whales (Megaptera novaeangliae) indicate limited effectiveness of sonar mitigation
Wensveen, Paul; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; vonBenda-Beckmann, Sander; Sivle, Lise Doksæter; Visser, Fleur; Cure, Charlotte; Tyack, Peter L.; Miller, Patrick James O'Malley (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 ... -
Modeling Effectiveness of Gradual Increases in Source Level to Mitigate Effects of Sonar on Marine Mammals
Benda-Beckmann, Alexander M. von; Wensveen, Paul; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick J.O.; Tyack, Peter L.; Ainslie, Michael A (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 ... -
Modeling potential masking of echolocating sperm whales exposed to continuous 1-2 kHz naval sonar
von Benda-Beckmann, Alexander M.; Isojunno, Saana; Zandvliet, Maik; Ainslie, Michael A.; Wensveen, Paulus Jacobus; Tyack, Peter L.; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick James O. (2021-04-30)Modern active sonar systems can (almost) continuously transmit and receive sound, which can lead to more masking of important sounds for marine mammals than conventional pulsed sonar systems transmitting at a much lower ... -
The social context of individual foraging behaviour in long-finned pilot whales (Globicephala melas)
Visser, Fleur; Miller, Patrick J.O.; Antunes, Ricardo; Oudejans, Machiel G; Mackenzie, M.L.; Aoki, K.; Lam, Frans-Peter A.; Kvadsheim, Petter Helgevold; Huisman, J; Tyack, Peter L. (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. ... -
