Background Ecosystem interactions
For several centuries, fishing have played an important role in the function and dynamics of the Barents Sea ecosystem. In early periods fisheries were purely coastal and had limited effects on the ecosystem. With the development of offshore fisheries the impact on fish stocks and the ecosystem increased rapidly. At present, large-scale fisheries are one of the main factors determining the state and dynamics of the Barents Sea ecosystem.

Major impacts on the ecosystem in the Barents Sea from oil and gas activities have so far not been documented by monitoring or by research. There are uncertainties associated with potential effects of seismic activities.
Seismic sound has both physiological and behavioural effects on marine life. The physiological effects are limited to areas very close to the sound source. Behaviou...

The day-to-day impacts of shipping on the environment are caused by ordinary operational discharges and of organotin compounds from anti-fouling systems. To protect ships against corrosion, zinc anodes are used in addition to special paint. If zinc anodes are used in ballast tanks, the zinc content in the water discharged may exceed the tolerance limits of fish eggs and larvae...

The arctic environment is vulnerable and like many other human activities, tourism can have a wide range of impacts on the environment like pollution (oil, air, garbage, wastewater, ballast water), wildlife disturbance, and degradation of vegetation and historical and geological sites. Cruise-ship tourism is particularly intense in Svalbard, and to a lesser extent in Franz Josef Land in a ...
