(Limanda limanda, L.) with organochlorine 
compounds in the southern North Sea 
(especially HCB, HCH, PCB, DDT) 
Determination of the content, the accumulation, 
and distribution of metallic trace elements in 
marine fauna (Pb, Cd, Hg) 
Investigations about the annual cycle of micro

in the pelagic food web, and its balance of 
suspended matter 
Quantitative and qualitative stock assessment 
of the benthos in an area important for fisheries 
Direct measurements of the rate of sedimentation 
Determination of various physical parameters, 
dissolved components and particulate components 
in the water column 
Investigation about the spatial and temporal 
variance of aluminium concentration in the 
North Sea.
