    • 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 ...

    • 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, ...

    • Risiko for skade på laksefisk i omkringliggende oppdrettsanlegg ved etablering av undervanns- skytefelt på Korsnes Fort 

      Kvadsheim, Petter H.; Søvik, André Adelsten; Rokke, Eirik; Kolstrup, Marianne Lanzky; Forland, Tonje Nesse; Pedersen, Geir; Grimsbø, Endre; Dale, Ole Bendik; Cao, Yanran; Stene, Anne; Smedsrud, Morten (2022-03-25)
      Forsvaret ønsker å etablere et permanent øvingsområde i Korsfjorden. Øvingsaktiviteten vil innebære detonasjoner av små øvingsladninger (0,1–2 kg TNT) flere ganger om dagen, inntil 70 ladninger i året. Det er 4 konsesjoner ...

    • 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 ...
