    • Acoustic and foraging behavior of a Baird’s beaked whale, Berardius bairdii, exposed to simulated sonar 

      Stimpert, Alison; De Ruiter, Stacy Lynn; Southall, Brandon; Moretti, David; Falcone, Erin; Goldbogen, Jeremy; Friedlaender, Ari; Schorr, Greg; Calambokidis, John (2014-11-13) - Journal article
      Beaked whales are hypothesized to be particularly sensitive to anthropogenic noise, based on previous strandings and limited experimental and observational data. However, few species have been studied in detail. We describe ...
    • Automated peak detection method for behavioral event identification : detecting Balaenoptera musculus and Grampus griseus feeding attempts 

      Sweeney, David A.; Deruiter, Stacy L.; McNamara-Oh, Ye Joo; Marques, Tiago A.; Arranz, Patricia; Calambokidis, John (2019-04-04) - Journal article
      The desire of animal behaviorists for more flexible methods of conducting inter-study and inter-specific comparisons and meta-analysis of various animal behaviors compelled us to design an automated, animal behavior peak ...
    • 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 ...
    • Blue whales respond to simulated mid-frequency military sonar 

      Goldbogen, Jeremy A.; Southall, Brandon L.; De Ruiter, Stacy Lynn; Calambokidis, John; Friedlaender, Ari S.; Hazen, Elliott L.; Falcone, Erin A.; Schorr, Gregory S.; Douglas, Annie; Moretti, David J.; Kyburg, Chris; McKenna, Megan F.; Tyack, Peter Lloyd (2013) - Journal article
      Mid-frequency military (1–10 kHz) sonars have been associated with lethal mass strandings of deep-diving toothed whales, but the effects on endangered baleen whale species are virtually unknown. Here, we used controlled ...
    • Diving behavior and fine-scale kinematics of free-ranging Risso’s dolphins foraging in shallow and deep-water habitats 

      Arranz, Patricia; Benoit-Bird, Kelly; Friedlaender, Ari S.; Hazen, Elliot L.; Goldbogen, Jeremy A.; Stimpert, Alison K.; De Ruiter, Stacy Lynn; Calambokidis, John; Southall, Brandon; Fahlman, Andreas; Tyack, Peter Lloyd (2019-03-12) - Journal article
      Air-breathing marine predators must balance the conflicting demands of oxygen conservation during breath-hold and the cost of diving and locomotion to capture prey. However, it remains poorly understood how predators ...
    • First direct measurements of behavioural responses by Cuvier's beaked whales to mid-frequency active sonar 

      De Ruiter, Stacy Lynn; Southall, Brandon L.; Calambokidis, John; Zimmer, Walter M. X.; Sadykova, Dinara; Falcone, Erin A.; Friedlaender, Ari S.; Joseph, John E.; Moretti, David; Schorr, Gregory S.; Thomas, Len; Tyack, Peter Lloyd (2013) - Journal article
      Most marine mammal­ strandings coincident with naval sonar exercises have involved Cuvier's beaked whales (Ziphius cavirostris). We recorded animal movement and acoustic data on two tagged Ziphius and obtained the first ...
    • 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 ...
    • Sound production and associated behavior of tagged fin whales (Balaenoptera physalus) in the Southern California Bight 

      Stimpert, Alison; DeRuiter, Stacy; Falcone, Erin; Joseph, John; Douglas, Annie B; Moretti, David J; Friedlander, Ari S; Calambokidis, John; Gailey, Glenn; Tyack, Peter Lloyd; Goldbogen, Jeremy A (2015-08-03) - Journal article
      Background: For marine animals, acoustic communication is critical for many life functions, yet individual calling behavior is poorly understood for most large whale species. These topics are important for understanding ...
    • Using accelerometers to determine the calling behavior of tagged baleen whales 

      Goldbogen, Jeremy; De Ruiter, Stacy Lynn; Stimpert, Alison; Calambokidis, John; Friedlaender, Ari; Schorr, Greg; Moretti, David; Tyack, Peter Lloyd; Southall, Brandon (2014-07-15) - Journal article
      Low-frequency acoustic signals generated by baleen whales can propagate over vast distances, making the assignment of calls to specific individuals problematic. Here, we report the novel use of acoustic recording tags ...
