    • The 3S² experiments - studying the behavioral effects of naval sonar on northern bottlenose whales, humpback whales and minke whales 

      Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Sivle, Lise D.; Wensveen, Paul; Roos, Marjoleine; Tyack, Peter; Kleivane, Lars; Visser, Fleur; Curé, Charlotte; van Ijsselmuide, San (2015-11-03)
      In order to properly consider how behavioral responses to anthropogenic noise affect marine mammals and establish safety limits for sonar operations, there is a need to establish behavioral impact criteria. In order to ...
    • Behavioural response studies of cetaceans to naval sonar signals in Norwegian waters - 3S-2011 cruise report 

      Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Doksæter, Lise; Visser, Fleur; Kleivane, Lars; Ijsselmuide, Sander van; Samarra, Filipa; Wensveen, Paul; Curé, Charlotte; Hickmott, (2011-11-01)
      Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, and determine how potential behavioural changes may affect ...
    • Behavioural responses of cetaceans to naval signals in Norwegian waters - the 3S-2012 cruise report 

      Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Wensveen, Paul; Visser, Fleur; Sivle, Lise D.; Kleivane, Lars; Curé, Charlotte; Ensor, Paul; van Ijsselmuide, Sander; Dekeling, René (2012-11-01)
      Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, in order to regulate the use of powerful anthropogenic sound ...
    • Biological significance of sperm whale responses to sonar: Comparison with anti-predator responses 

      Curé, Charlotte; Isojunno, Saana; Visser, Fleur; Wensveen, Paul J.; Sivle, Lise Doksæter; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick J.O. (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 ...
    • Breathing patterns indicate cost of exercise during diving and response to experimental sound exposures in long-finned pilot whales 

      Isojunno, Saana; Aoki, Kagari; Curé, Charlotte; Kvadsheim, Petter Helgevold; O'Malley Miller, Patrick James (2018)
      Air-breathing marine predators that target sub-surface prey have to balance the energetic benefit of foraging against the time, energetic and physiological costs of diving. Here we use on-animal data loggers to assess ...
    • 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 ...
    • 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 P; 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 ...
    • 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 ...
    • Pilot Whales Attracted to Killer Whale Sounds: Acoustically-Mediated Interspecific Interactions in Cetaceans 

      Curé, Charlotte; Antunes, Ricardo; Samarra, Filipa; Alves, Ana Catarina; Visser, Fleur; Kvadsheim, Petter Helgevold; Miller, Patrick J.O. (2012)
      In cetaceans’ communities, interactions between individuals of different species are often observed in the wild. Yet, due to methodological and technical challenges very little is known about the mediation of these ...
    • 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 ...
    • Responses of male sperm whales (Physeter macrocephalus) to killer whale sounds: implications for anti-predator strategies 

      Curé, Charlotte; Antunes, Ricardo; Alves, Ana Catarina; Visser, Fleur; Kvadsheim, Petter Helgevold; Miller, Patrick J.O. (2013)
      Interactions between individuals of different cetacean species are often observed in the wild. Killer whales (Orcinus orca) can be potential predators of many other cetaceans, and the interception of their vocalizations ...
    • 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 ...
