    • 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 ...

    • Behavioural responses of cetaceans to naval sonar signals – the 3S-2013 cruise report 

      Kvadsheim, Petter; Lam, Frans-Peter; Miller, Patrick; Wensveen, Paul; Visser, Fleur; Sivle, Lise Doksæter; Oudejans, Machiel; Kleivane, Lars; Curé, Charlotte; Ensor, Paul; van Ijsselmuide, Sander; Dekeling, René (2014-06-20)
      The 3S-projects is an international collaborative effort with the aim to investigate behavioral reactions of cetaceans to naval sonar signals, in order to establish safety limits for sonar operations. This report summarizes ...

    • Behavioural responses of wild, spawning Atlantic cod (Gadus morhua L.) to seismic airgun exposure 

      McQueen, Kate; Skjæraasen, Jon Egil; Nyqvist, D; Olsen, Esben Moland; Karlsen, Ørjan; Meager, Justin James; Kvadsheim, Petter Helgevold; Handegard, Nils Olav; Forland, Tonje Nesse; de Jong, Karen; Sivle, Lise Doksæter (2023-03-11)
      Seismic airgun surveys to map petroleum deposits in the seabed may impact behaviour of marine animals over large distances. Understanding whether fish spawning behaviour is affected by this anthropogenic noise source is ...

    • 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 ...

    • Continuous sound from a marine vibrator causes behavioural responses of free-ranging, spawning Atlantic cod (Gadus morhua) 

      McQueen, Kate; Sivle, Lise Doksæter; Forland, Tonje Nesse; Meager, Justin James; Skjæraasen, Jon Egil; Olsen, Esben Moland; Karlsen, Ørjan; Kvadsheim, Petter Helgevold; de Jong, Karen (2024-01-09)
      Marine vibrators are a new technology being developed for seismic surveys. These devices can transmit continuous instead of impulsive sound and operate over a narrower frequency band and at lower peak pressure than airguns, ...

    • 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 ...

    • 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 ...

    • 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, ...

    • 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 ...

    • Severity Scoring of Behavioral Responses of Sperm Whales (Physeter macrocephalus) to Novel Continuous versus Conven tional Pulsed Active Sonar 

      Curé, Charlotte; Isojunno, Saana; Siemensma, Marije; Wensveen, Paul; Buisson, celia; Sivle, Lise Doksæter; Benti, Benjamin; Roland, Rune; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick James O. (2021-04-19)
      Controlled exposure experiments (CEEs) have demonstrated that naval pulsed active sonar (PAS) can induce costly behavioral responses in cetaceans similar to antipredator responses. New generation continuous active sonars ...

    • Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site 

      McQueen, Kate; Meager, Justin James; Nyqvist, Daniel; Skjæraasen, Jon Egil; Olsen, Esben Moland; Karlsen, Ørjan; Kvadsheim, Petter Helgevold; Handegard, Nils Olav; Sivle, Lise Doksæter; Forland, Tonje Nesse (2022-11-15)
      Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ...
