    • Dose-response relationships for the onset of avoidance of sonar by free-ranging killer whales 

      Miller, Patrick J.O.; Antunes, Ricardo; Wensveen, Paul; Samarra, Filipa I. P.; Alves, Ana Catarina; Tyack, Peter L.; Kvadsheim, Petter Helgevold; Kleivane, Lars; Lam, Frans-Peter A.; Ainslie, Michael A; Thomas, Len (2014)
      Eight experimentally controlled exposures to 1−2 kHz or 6−7 kHz sonar signals were conducted with four killer whale groups. The source level and proximity of the source were increased during each exposure in order to reveal ...
    • Modeling Effectiveness of Gradual Increases in Source Level to Mitigate Effects of Sonar on Marine Mammals 

      Benda-Beckmann, Alexander M. von; Wensveen, Paul; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick J.O.; Tyack, Peter L.; Ainslie, Michael A (2014)
      Ramp-up or soft-start procedures (i.e., gradual increase in the source level) are used to mitigate the effect of sonar sound on marine mammals, although no one to date has tested whether ramp-up procedures are effective ...
