Earlier pollution is still creating problems

Pollutants are transported to marine areas from a number of different sources. High levels of hazardous substances in some fjords and harbours are mainly the result of earlier industrial discharges. The use of chemical pesticides in the agricultural sector can also play a part.

Chemicals accumulate in the food chain

A number of the hazardous substances found in coastal areas are very persistent, which means that they break down very slowly in the environment. Some, such as PCBs and dioxins, can cause damage even in small concentrations.

Situation improved in polluted fjords

More than 20 years of monitoring hazardous substances along the Norwegian coast has provided a good overview of the content of contaminants in fish, shellfish and seabed sediments.

The Barents Sea

The Barents Sea is one of the world’s most productive sea areas, supporting varied benthic communities and large populations of fish, seabirds and marine mammals. It is still clean and rich in resources, but is under pressure from human activity, climate change and acidification.

The Norwegian Sea

The Norwegian Sea is the part of the North Atlantic between Norway, Svalbard and Iceland. In general, the state of the environment is considered to be good, and much of the water column and deep seabed is relatively undisturbed. However, certain species and areas are clearly affected by human activity.

The North Sea and Skagerrak

The North Sea and Skagerrak are more strongly influenced by human activity than the Norwegian Sea and the Barents Sea: they contain some of the busiest shipping routes in the world and support intensive fisheries and a large-scale oil and gas industry. Climate change and ocean acidification are expected to have increasing impacts in the future.

Trajectory Models

The Norwegian Meteorological Institute has developed sophisticated models that calculate trajectories for everything from oil spills and fishing boats to man overboard.  Forecasts can be issued at any time of day, every day, all year.
