      Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, and determine how potential behavioural changes may affect ...

    • Behavioural responses of cetaceans to naval signals in Norwegian waters - the 3S-2012 cruise report 

      Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Wensveen, Paul; Visser, Fleur; Sivle, Lise D.; Kleivane, Lars; Curé, Charlotte; Ensor, Paul; van IJsselmuide, Sander; Dekeling, René (2012-11-01)
      Marine mammals are sensitive to sound in their environment and there is a continuing need to quantify the sensitivity of the animals to behavioural disturbance, in order to regulate the use of powerful anthropogenic sound ...

    • Cetaceans and naval sonar : the 3S-2009 cruise report 

      Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Kleivane, Lars; Alves, Ana Catarina; Antunes, Ricardo; Bocconcelli, Alex; van IJsselmuide, Sander; Olivierse, Marijke; Visser, Fleur (2009)
      Forsvaret har utrykt behov for å få kartlagt sjøpattedyrs følsomhet overfor sonarsignaler, også atferdsmessige påvirkninger. 3S-konsortiet, som for tiden består av fire partnere, FFI, Woods Hole Oceanographic Institution ...

    • Effect of naval sonar exposure on killer whales and humpback whales – 3S-2023 cruise report 

      Kvadsheim, Petter H.; Miller, Patrick J.O.; Lam, Frans-Peter A.; Wensveen, Paul J.; Bort, Jacqueline; Burslem, Alec; Giovannini, Giorgia; Hayward, Ellen; van Ijsselmuide, Sander P.; Kleivane, Lars; Reesor, Craig; van Riet, Martijn W.G.; Roland, Rune; Siemensma, Marije L.; Sato, George (2024-04-02)
      3S (Sea mammals and Sonar Safety) is a multidisciplinary and international collaboration studying how naval sonar affects cetaceans. The goal is to gain information necessary to manage the risk to cetaceans without ...

    • Effects of naval sonar on seals 

      Kvadsheim, Petter H.; Sevaldsen, Erik; Scheie, David; Folkow, Lars P.; Blix, Arnoldus S. (2010)
      There is a growing concern that active military sonars might injure or harm marine mammals. We have therefore done controlled exposure experiments on captive hooded seals to investigate behavioral, physiological and possible ...

    • Effekter av menneskeskapt støy på havmiljø - rapport til Miljødirektoratet om kunnskapsstatus 

      Kvadsheim, Petter H.; Sivle, Lise D.; Hansen, Rune Roland; Karlsen, Hans Erik (2017-01-13)
      Menneskelig aktivitet har ført til en betydelig økning av støynivået i havet. Økningen i bakgrunnsstøynivået skyldes primært økt skipsfart, som kan maskere dyrenes evne til akustisk kommunikasjon, til å finne og fange ...

    • Herring (sild), killer whales (spekkhogger) and sonar - the 3S-2006 cruise report with preliminary results

      Denne rapporten oppsummerer resultatet fra et internasjonalt forskningstokt i Vestfjorden i november 2006. Bakgrunnen for undersøkelsen er påstander om at forsvarets bruk av sonarer skremmer bort sild og spekkhoggere fra ...

    • The potential impact of 1-8 kHz active sonar on stocks of juvenile fish during sonar exercises 

      Sevaldsen, Erik; Kvadsheim, Petter H. (2005)
      The mortality threshold for juvenile herring exposed to sonar signals is 180-190 dB (re 1μPa), and for other species even higher. This report analyses the potential impact of sonar transmissions on recruitment to important ...
