Suspended matter is the main carrier of pollu 
tants into the sediments. In order to balance 
pollutant transport, both agents have to be 
analysed. 
By this it will become possible to study 
long-term developments, as well as transport 
and depository activities. 
Due to the sedimentological changes evident in 
this muddy area, the possible accumulation of 
pollutants should be studied. 
Velocity of sediment - water transfer processes 
can be deduced from the velocity of radionuclides 
which undergo geochemical fractionization. 
Information to judge the contamination of 
sediments. 
The composition of the sediments is an important 
basis for all oceanographic disciplines including 
fisheries research and marine ecology.
