The  main  effort  within  this  collaboration  is
concentrated  on  sources,  transports,  and
sinks  of  suspended  matter  in  the  Elbe  estuary,
in  the  German  parts  of  the  Wadden  Sea  and  in  the
German  Bight.  A  thorough  knowledge  of  these
processes  is  important  for  the  fate  of
pollutants  which  are  frequently  adsorbed  on
suspended  particles,  and  their  distribution  in
German  Bight  and  in  the  North  Sea.

Sea  using  one  method  for  sample  taking  and  analysis. ­
  Assessment  of  input  concentrations  and
