Comment 
ZISCH is an example of a co-ordinated inter 
disciplinary project aiming at the quanitfi- 
cation of turn-over of important pollutants 
which enter the North Sea. Apart from the 
present state of pollution of the North Sea 
the pattern of input and the sources of 
pollution are of special interest. As for 
anthropogenic inputs the circulation pattern 
and the fate of the pollutants are studied 
and an input balance is to be calculated.
