The Institute of Marine Research (IMR) opens a 2-year post doctoral research position (with an option for 2 years extension) available to work with projects related to environmental impact of seismic exposure on marine life. The post doctor will be included in a core team of technicians and scientists working with environmental impact of seismic sound to marine life.

Norway has three business areas of particular importance: fishery, aquaculture, and oil and gas. The coexistence of these business areas requires sustainable management of the resources based on scientific knowledge.

Anthropogenic noise includes seismic shooting, underwater explosions, electromagnetic investigations, ship noise, noise from wind turbines, and more. Anthropogenic noise in the sea will increase the ambient noise, thus potentially influencing fish and marine mammal's ability to communicate and mask biologically important sounds.

Seismic sound has its main energy in the frequency range where most fish species has its best hearing, and sound exposure from seismic activities has been shown to alter fish distribution and behaviour. However, there are still uncertainties regarding how fish behaviour is affected by sound exposure from seismic activities, and how this vary between different species, life stages and behavioural modes, e.g. feeding and spawning situations. To achieve more knowledge, IMR is cooperating with Norwegian and international institutions within the field of how anthropogenic sound in the ocean is affecting marine life. In addition, IMR is a central advisor regarding effects of seismic shooting, sound from underwater installations, and explosions in the sea.

The post doctor will be involved in existing projects, as well as in writing applications for new projects and will be given main responsibility within fields of interest and according to competence. The focus area will be research within the effect of seismic sound on fish behaviour.

The candidate will be involved in:

• Ongoing projects targeting distances and thresholds of witch mackerel are affected by sound from seismic shooting as well as the effect on feeding and feeding motivation. This will involve field work at Austevoll research station with mackerel in net pens. Behavioural monitoring will be done with echosounder and video. Sound exposure will be measured in the form of sound pressure and particle motion. Experience with this type of instrumentation is therefore advantageous.

In addition, the candidate may be involved in:

• Future projects are how seismic sound may affect spawning and spawning migrations, as well as how fishing operations are affected by seismic activity. Such work will involve field work at sea.
• The candidate will also be involved in advisory tasks related to regulation of seismic activity in Norwegian waters.
• Participate as supporting representative for IMR in working groups targeting regulation of underwater noise.
• Simulations of sound propagation to model potential impact on fish and marine mammals under different scenarios.

It is expected that the candidate will publish the results in reports and international journals and participate in relevant conferences and workshops.

The requirements to the candidate are as follows:

• PhD in physics, mathematics, geophysics, fisheries biology, engineering or similar. Good skill in mathematics and specialization in marin
