  • Avoidance responses of minke whales to 1–4 kHz naval sonar 

    Kvadsheim, Petter H.; DeRuiter, Stacy; Sivle, Lise D.; Goldbogen, Jeremy; Roland-Hansen, Rune; Miller, Patrick J. O.; Lam, Frans-Peter A.; Calambokidis, John; Friedlaender, Ari; Visser, Fleur; Tyack, Peter L.; Kleivane, Lars; Southall, Brandon (2017-08-15) - Journal article
    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 ...
  • Beaked whales respond to simulated and actual navy sonar 

    Tyack, Peter L.; Zimmer, Walter M. X.; Moretti, David; Southall, Brandon L.; Claridge, Diane E.; Durban, John W.; Clark, Christopher W.; D'Amico, Angela; DiMarzio, Nancy; Jarvis, Susan; McCarthy, Elena; Morrissey, Ronald; Ward, Jessica; Boyd, Ian L. (2011-03-14) - Journal article
    Beaked whales have mass stranded during some naval sonar exercises, but the cause is unknown. They are difficult to sight but can reliably be detected by listening for echolocation clicks produced during deep foraging ...
  • Disturbance-specific social responses in long-finned pilot whales, Globicephala melas 

    Visser, Fleur; Curé, Charlotte; Kvadsheim, Petter H.; Lam, Frans-Peter A.; Tyack, Peter L.; Miller, Patrick J O (2016-06-29) - Journal article
    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 ...
  • Experimental field studies to measure behavioral responses of cetaceans to sonar 

    Southall, Brandon L.; Nowacek, Douglas P.; Miller, Patrick J. O.; Tyack, Peter L. (2016-12-06) - Journal item
    Substantial recent progress has been made in directly measuring behavioral responses of free-ranging marine mammals to sound using controlled exposure experiments. Many studies were motivated by concerns about observed and ...
  • Investigating the surfacing and diving behaviour and availability of long-finned pilot whales and quantifying the effects of anthropogenic sound on density and strandings of cetaceans in the northeast Atlantic 

    Jewell, Rebecca (University of St Andrews, 2014-06-26) - Thesis
    The size and trend of a population is fundamental to the assessment of its conservation status, yet cetacean abundance data are often biased and lack statistical power to detect trends. As a result, the conservation status ...
  • Lack of behavioural responses of humpback whales (Megaptera novaeangliae) indicate limited effectiveness of sonar mitigation 

    Wensveen, Paul J.; Kvadsheim, Petter H.; Lam, Frans-Peter A.; von Benda-Beckmann, Alexander M.; Sivle, Lise D.; Visser, Fleur; Curé, Charlotte; Tyack, Peter L.; Miller, Patrick J. O. (2017-11-15) - Journal article
    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 tissue and blood gas kinetics in coastal and offshore common bottlenose dolphins, Tursiops truncatus 

    Fahlman, Andreas; Jensen, Frants; Tyack, Peter L.; Wells, Randall (2018-07-17) - Journal article
    Bottlenose dolphins (Tursiops truncatus) are highly versatile breath-holding predators that have adapted to a wide range of foraging niches from rivers and coastal ecosystems to deep-water oceanic habitats. Considerable ...
  • Risso's dolphins plan foraging dives 

    Arranz, Patricia; Benoit-Bird, Kelly J.; Southall, Brandon L.; Calambokidis, John; Friedlaender, Ari S.; Tyack, Peter L. (2018-02-28) - Journal article
    Humans remember the past and use that information to plan future actions. Lab experiments that test memory for the location of food show that animals have a similar capability to act in anticipation of future needs, but ...
  • Spatio-temporal variation in click production rates of beaked whales : implications for passive acoustic density estimation 

    Warren, Victoria E.; Marques, Tiago A.; Harris, Danielle; Thomas, Len; Tyack, Peter L.; Aguilar de Soto, Natacha; Hickmott, Leigh S.; Johnson, Mark P. (2017-03) - Journal article
    Passive acoustic monitoring has become an increasingly prevalent tool for estimating density of marine mammals, such as beaked whales, which vocalize often but are difficult to survey visually. Counts of acoustic cues ...
  • Successful suction-cup tagging of a small delphinid species, Stenella attenuata : insights into whistle characteristics 

    Silva, Tammy L.; Aran Mooney, T.; Sayigh, Laela S.; Baird, Robin W.; Tyack, Peter L. (2017-04-13) - Journal article
  • Understanding the population consequences of disturbance 

    Pirotta, Enrico; Booth, Cormac G.; Costa, Daniel P.; Fleishman, Erica; Kraus, Scott D.; Lusseau, David; Moretti, David; New, Leslie F.; Schick, Robert S.; Schwarz, Lisa K.; Simmons, Samantha E.; Thomas, Len; Tyack, Peter L.; Weise, Michael J.; Wells, Randall S.; Harwood, John (2018-09-12) - Journal item
    Managing the nonlethal effects of disturbance on wildlife populations has been a long-term goal for decision makers, managers, and ecologists, and assessment of these effects is currently required by European Union and ...
