    • 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 ...

    • 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 ...

    • Marine mammals and sonar: dose-response studies, the risk-disturbance hypothesis and the role of exposure context 

      Harris, Catriona; Thomas, Len; Falcone, Erin; Hildebrand, Jon; Houser, Dorian; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick James O'Malley; Moretti, David; Read, Andrew; Slabbekoorn, Hans; Southall, Brandon L.; Tyack, Peter Lloyd; Wartzok, D.; Janik, V. M. (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 ...

    • Naval sonar disrupts foraging in humpback whales 

      Sivle, Lise Doksæter; Wensveen, Paul Jacobus; Kvadsheim, Petter Helgevold; Lam, Frans-Peter Alexander; Visser, Fleur; Curé, Charlotte; Harris, Catriona M.; Tyack, Peter Lloyd; Miller, Patrick James O'Malley (2016)
      Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...

    • Northern bottlenose whales in a pristine environment respond strongly to close and distant navy sonar signals 

      Wensveen, Paul J.; Isojunno, Saana; Hansen, Rune Roland; von Benda-Beckmann, Alexander M.; Kleivane, Lars; van IJsselmuide, Sander; Lam, Frans-Peter Alexander; Kvadsheim, Petter Helgevold; DeRuiter, Stacy L.; Curé, Charlotte; Narazaki, Tomoko; Tyack, Peter Lloyd; Miller, Patrick James O'Malley (2019-03-20)
      Impact assessments for sonar operations typically use received sound levels to predict behavioural disturbance in marine mammals. However, there are indications that cetaceans may learn to associate exposures from distant ...

    • Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale 

      Curé, Charlotte; Sivle, Lise Doksæter; Visser, Fleur; Wensveen, Paul J.; Isojunno, Saana; Harris, Catriona M.; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick James O'Malley (2015)
      Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ...

    • Predicting acoustic dose associated with marine mammal behavioural responses to sound as detected with fixed acoustic recorders and satellite tags 

      von Benda-Beckmann, Alexander M.; Wensveen, Paul Jacobus; Prior, Mark; Ainslie, Michael; Hansen, Rune Roland; Isojunno, Saana; Lam, Frans-Peter Alexander; Kvadsheim, Petter Helgevold; Miller, Patrick James O'Malley (2019-03-08)
      To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite ...

    • Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds 

      Isojunno, Saana; Curé, Charlotte; Kvadsheim, Petter Helgevold; Lam, Frans-Peter Alexander; Tyack, Peter Lloyd; Wensveen, Paul Jacobus; Miller, Patrick James O'Malley (2016)
      The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ...

    • Vocal matching of naval sonar signals by long-finned pilot whales (Globicephala melas) 

      Alves, Ana; Antunes, Ricardo; Bird, Anna; Tyack, Peter L.; Miller, Patrick James O'Malley; Lam, Frans-Peter A.; Kvadsheim, Petter Helgevold (2014)

    • When the noise goes on: received sound energy predicts sperm whale responses to both intermittent and continuous navy sonar 

      Isojunno, Saana; Wensveen, Paul Jacobus; Lam, Frans-Peter Alexander; Kvadsheim, Petter Helgevold; Benda-Beckmann, Alexander M. von; Lòpez, Lucia; Kleivane, Lars; Siegall, Elidh; Miller, Patrick James O'Malley (2020-04-08)
      Anthropogenic noise sources range from intermittent to continuous, with seismic and navy sonar technology moving towards near-continuous transmissions. Continuous active sonar (CAS) may be used at a lower amplitude than ...
