Diversity and population dynamics of eu- 
and sublittoral benthos. 
Qualitative species determination in 
cluding life cycle stages. 
Geographical and annual variation of contamination 
with organochlorine compounds and mercury. 
Basic study on the variation of pollutants 
concentration in different bird specie^, as 
well as potential effects of pollutants on 
hatching success. 
Main effort is concentrated on selected profiles 
in tidal flat areas of the reach of maximum 
turbidity. 
Main effort is concentrated on selected fixed 
stations within the maximum turbidity reach. 
Within the framework of the JMG - 
Monitoring Programme 
The project’s aim is to set economically 
justifiable limits to the input balance of 
pollutants into the North Sea by determination 
of the total amount of AOX.
