    • Naval sonar disrupts foraging in humpback whales 

      Sivle, Lise Doksæter; Wensveen, Paul Jacobus; Kvadsheim, Petter Helgevold; Lam, Frans-Peter Alexander; Visser, Fleur; Curé, Charlotte; Harris, Catriona M.; Tyack, Peter Lloyd; Miller, Patrick James O'Malley (2016)
      Modern long-range naval sonars are a potential disturbance for marine mammals and can cause disruption of feeding in cetaceans. We examined the lunge-feeding behaviour of humpback whales Megaptera novaeangliae before, ...

    • Predicting acoustic dose associated with marine mammal behavioural responses to sound as detected with fixed acoustic recorders and satellite tags 

      von Benda-Beckmann, Alexander M.; Wensveen, Paul Jacobus; Prior, Mark; Ainslie, Michael; Hansen, Rune Roland; Isojunno, Saana; Lam, Frans-Peter Alexander; Kvadsheim, Petter Helgevold; Miller, Patrick James O'Malley (2019-03-08)
      To understand the consequences of underwater noise exposure for cetaceans, there is a need for assessments of behavioural responses over increased spatial and temporal scales. Bottom-moored acoustic recorders and satellite ...

    • Sperm whales reduce foraging effort during exposure to 1-2 kH z sonar and killer whale sounds 

      Isojunno, Saana; Curé, Charlotte; Kvadsheim, Petter Helgevold; Lam, Frans-Peter Alexander; Tyack, Peter Lloyd; Wensveen, Paul Jacobus; Miller, Patrick James O'Malley (2016)
      The time and energetic costs of behavioral responses to incidental and experimental sonar exposures, as well as control stimuli, were quantified using hidden state analysis of time series of acoustic and movement data ...

    • When the noise goes on: received sound energy predicts sperm whale responses to both intermittent and continuous navy sonar 

      Isojunno, Saana; Wensveen, Paul Jacobus; Lam, Frans-Peter Alexander; Kvadsheim, Petter Helgevold; Benda-Beckmann, Alexander M. von; Lòpez, Lucia; Kleivane, Lars; Siegall, Elidh; Miller, Patrick James O'Malley (2020-04-08)
      Anthropogenic noise sources range from intermittent to continuous, with seismic and navy sonar technology moving towards near-continuous transmissions. Continuous active sonar (CAS) may be used at a lower amplitude than ...
