    • 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 ...

    • 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 ...
