The 3S3 experiment data report - using operational naval sonars to study the effects of continuous active sonar, and source proximity, on sperm whales
Kvadsheim, Petter H.; Isojunno, Saana; Curé, Charlotte; Siemensma, Marije L.; Wensveen, Paul; Lam, Frans-Peter A.; Roland, Rune; Benti, Benjamin; Sivle, Lise D; Burslem, Alec; Kleivane, Lars; Miller, Patrick J.O. (2021-03-18)The 3S project is an international collaborative effort with the aim to investigate behavioral reactions of cetaceans to naval sonar signals. The objectives of the third phase of the project (3S3) were to investigate if ... -
The 3S² experiments - studying the behavioral effects of naval sonar on northern bottlenose whales, humpback whales and minke whales
Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Sivle, Lise D.; Wensveen, Paul; Roos, Marjoleine; Tyack, Peter; Kleivane, Lars; Visser, Fleur; Curé, Charlotte; van IJsselmuide, Sander (2015-11-03)In order to properly consider how behavioral responses to anthropogenic noise affect marine mammals and establish safety limits for sonar operations, there is a need to establish behavioral impact criteria. In order to ... -
Behavioural response studies of cetaceans to naval sonar signals in Norwegian waters - 3S-2011 cruise report
Kvadsheim, Petter H.; Lam, Frans-Peter; Miller, Patrick; Doksæter, Lise; Visser, Fleur; Kleivane, Lars; van IJsselmuide, Sander; Samarra, Filipa; Wensveen, Paul; Curé, Charlotte; Hickmott, (2011-11-01)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, 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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ...
