The map comparisons you can see here visualize the dynamics of our waters throughout the year and from year to year. The services will provide a better basis for understanding and managing stocks and activities in coastal and marine areas in the north.

It is assumed that several million tons of oil is discharged into rivers and oceans worldwide every year. Some of this oil contamination consists of acute spills.

Ocean currents are essential for life in the sea – and for the climate of the lands that border on the waters. 

Vessel movements in the seas off Norway are on the increase. The environmental effect of this activity depends in part on developments in the petroleum sector, where great uncertainty prevails about future trends.

The petroleum sector is the largest source of greenhouse gas (GHG) emissions in Norway. Efforts are being made to develop improved methods to monitor the industry’s impact on marine life.

Seafood ranks as Norway’s second-largest export industry. To maintain this sector, the country must manage its marine natural resources sustainably and keep its seas clean and productive.

Norway’s aquaculture industry is expanding fast. Its biggest environmental impacts take the form of escaped farmed salmon and salmon (sea) lice.

Over the past 20–30 years, Norway has done a great deal to reduce discharges of nutrients from agriculture, municipal waste water treatment and industry. Similar steps have been taken in much of the rest of Europe, and these also benefit Norway.

Norwegian coastal waters can be divided into four main areas: the Skagerrak, the North Sea, the Norwegian Sea and the Barents Sea, with different levels of nutrient inputs.

Eutrophication in coastal waters and fjords in Norway is caused by discharges of nutrients from fish farming, runoff from agricultural areas, and inputs from industry and municipal waste water treatment.
