Behavior of captive herring exposed to naval sonar transmissions (1.0-1.6 kHz) throughout a yearly cycle
Doksæter, Lise Henriksen; Handegard, Nils Olav; Godø, Olav Rune; Kvadsheim, Petter Helgevold; Nordlund, Nina (2012)Atlantic herring, Clupea harengus, is a hearing specialist, and several studies have demonstrated strong responses to man-made noise, for example, from an approaching vessel. To avoid negative impacts from naval sonar ... -

Behavioural responses of wild, spawning Atlantic cod (Gadus morhua L.) to seismic airgun exposure
McQueen, Kate; Skjæraasen, Jon Egil; Nyqvist, D; Olsen, Esben Moland; Karlsen, Ørjan; Meager, Justin James; Kvadsheim, Petter Helgevold; Handegard, Nils Olav; Forland, Tonje Nesse; de Jong, Karen; Sivle, Lise Doksæter (2023-03-11)Seismic airgun surveys to map petroleum deposits in the seabed may impact behaviour of marine animals over large distances. Understanding whether fish spawning behaviour is affected by this anthropogenic noise source is ... -
Spawning Atlantic cod (Gadus morhua L.) exposed to noise from seismic airguns do not abandon their spawning site
McQueen, Kate; Meager, Justin James; Nyqvist, Daniel; Skjæraasen, Jon Egil; Olsen, Esben Moland; Karlsen, Ørjan; Kvadsheim, Petter Helgevold; Handegard, Nils Olav; Sivle, Lise Doksæter; Forland, Tonje Nesse (2022-11-15)Seismic airgun surveys may disturb and displace fish at large ranges. If such displacement causes fish to abandon spawning grounds, reproductive success could be impacted. To investigate whether airgun sound causes cod ...
