Curé, Charlotte; Isojunno, Saana; Visser, Fleur; Wensveen, Paul J.; Sivle, Lise Doksæter; Kvadsheim, Petter Helgevold; Lam, Frans-Peter A.; Miller, Patrick J.O. (2016)A key issue when investigating effects of anthropogenic noise on cetacean behavior is to identify the biological significance of the responses. Predator presence can be considered a natural high-level disturbance stimulus ... -
Breathing patterns indicate cost of exercise during diving and response to experimental sound exposures in long-finned pilot whales
Isojunno, Saana; Aoki, Kagari; Curé, Charlotte; Kvadsheim, Petter Helgevold; O'Malley Miller, Patrick James (2018)Air-breathing marine predators that target sub-surface prey have to balance the energetic benefit of foraging against the time, energetic and physiological costs of diving. Here we use on-animal data loggers to assess ... -
Capture and Release of Minke Whales Offers New Research Opportunities, Including Measurements of Mysticete Hearing
Kleivane, Lars; Kvadsheim, Petter Helgevold; Vinje, Anna Victoria Pyne; Mulsow, Jason; Ølberg, Rolf-Arne; Teilmann, Jonas; Harms, Craig; Houser, Dorian (2024-09)Knowledge about species-specific hearing is vital to assessing how anthropogenic noise impacts marine mammals. Unfortunately, no empirical audiogram exists for any mysticete whale. We therefore developed a catch-and-release ... -

Doksæter, Lise Henriksen; Kvadsheim, Petter Helgevold; Fahlman, Andreas; Lam, Frans-Peter A.; Tyack, Peter L.; Miller, Patrick J.O. (2012)Anthropogenic underwater sound in the environment might potentially affect the behavior of marine mammals enough to have an impact on their reproduction and survival. Diving behavior of four killer whales (Orcinus orca), ... -
Continuous sound from a marine vibrator causes behavioural responses of free-ranging, spawning Atlantic cod (Gadus morhua)
McQueen, Kate; Sivle, Lise Doksæter; Forland, Tonje Nesse; Meager, Justin James; Skjæraasen, Jon Egil; Olsen, Esben Moland; Karlsen, Ørjan; Kvadsheim, Petter Helgevold; de Jong, Karen (2024-01-09)Marine vibrators are a new technology being developed for seismic surveys. These devices can transmit continuous instead of impulsive sound and operate over a narrower frequency band and at lower peak pressure than airguns, ... -
