Summary 
An experiment "chemical marine pollution” has been performed 
in the German Bight to investigate possibilities for determin- 
ing chemical parameters from the sea surface. As an example, 
the continued dumping of waste solutions from titanium dioxide 
'production northwest of Helgoland Island was taken. Here, dis- 
tinct color variations in sea water can be observed. The rele- 
vant chemical processes have been monitored by Deutsches Hy- 
drographisches Institut for a number of years by means of re- 
search vessels. The flight campaign on 25 August 1976 is des- 
cribed, simultaneous measurements at sea as well as pictures 
and data from remote sensing are presented, and examples for 
digital image processing are given, Experience from the ex- 
periment can be taken as an valuable input for future modified 
flight campaigns as well as a basis for later satellite use. 
Briefly, a LANDSAT 1 picture is discussed, where traces are 
discernible in the investigation area that may be related to 
the same dumping activities.
