Resultater fra 3 års overvåking av partikulær oljeforurensning i havet utenfor norskekysten
In the 3 year period May 1975 - April 1978, monitoring of the particulate oil pollution in the Skagerrak and the North Sea has been carried out, following extensive base-line investigations in the first half of 1975. More occasional observations have been made in the Barents Sea. In the Skagerrak ta...

In the North Sea tar balls were present in two thirds of the samples, an increase from less than one half since the base-line work.
