Evaluation of Fisheries Sonar for Whale Detection in Relation to Seismic Survey Operations
(Peer reviewed; Journal article, 2008)
Behavioural effects of seismic dose escalation exposure on captive mackerel (Scomber scombrus)
(Rapport fra havforskningen;;34 - 2017, Research report, 2017)
Petroleum and fisheries are two of the most important industries in Norway, and the goal for management is sustainable coexistence for both. Mackerel is an important pelagic fishery resource, and mackerel can very well ...
Evaluating the effect of seismic surveys on fish — the efficacy of different exposure metrics to explain disturbance
(Journal article; Peer reviewed, 2013-06-05)
To assess potential disturbance effects on fish from seismic air-gun surveys, we described several metrics to characterize the exposures from such surveys, including the number of emissions by area and time, and metrics ...
Noise Dose for Aquatic Animals: Preliminary Estimates for Two Seismic Surveys
(Conference object, 2010-10)
Two major air-gun exposure experiments have been conducted in Norwegian waters: The Nordkappbank experiment in 1992 [Can. J. Fish. Res. Aq. Sci., 1996, Vol. 53, pp. 2238-2249] and the Vesterålen experiment in 2009 [Fisken ...
Noise dose for aquatic animals: Preliminary estimates for two seismic surveys. (A)
(Conference object, 2010-03)
In humans, a daily noise dose is defined and used to regulate noise exposure in the working environment. This is an integrated measure of sound intensity over the working day, typically 8 h in duration. When investigating ...

Scientific basis for management of fish resources with regard to seismic exploration
(Fisheries and offshore petroleum exploitation 2nd internationl conference Bergen, Norway,April 6-8, 1992, Conference object, 1992)
Effects of seismic shooting on local abundance and catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus)
(Journal article; Peer reviewed, 1996)
To determine whether seismic exploration affected abundance or catch rates of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus), acoustic mapping and fishing trials with trawls and longlines were conducted in the ...
Skadeeffekter på egg, larver og yngel fra seismiske undersøkelser.
(Rapport/Notat Fysisk oseanografiNr. FO 8505, Working paper, 1985)
For å finne ut om bruk av seismiske energikilder kan skade fisk, eksponerte vi egg, larver og yngel av torsk (Gadus morhua L.) med en liten luftkanon (Bolt 600B) og yngel med en stor luftkanon (Bolt 1500C) og med en vannkanon ...
