The  treaty  »on  the  use  and  administration  of  the
territorial  sea  between  3  and  12  nautical  miles«
fixes  the  substantial  and  for  practice  particularly
Important  aspects:
•  The  construction  of  the  wind  farm  »Riffgat«  Is
being  based  on  an  assured  basis  of  international ­
  law;
•  The  delimitation  of  responsibilities  for  marine ­
  cables,  pipelines,  wind  farms,  rights  for
exploitation  and  uses  is  being  done  along
the  line  of  the  German-Dutch  treaty  of  the
continental  shelf  from  1964;
•  The  access  to  the  high  sea  from  the  harbours
of  Emden,  Delfzijl  and  Eemshaven  remains
without  hindrance;

•  The  whole  marine  traffic  management  in
that  area  will  be  concentrated  In  one  joint
vessel  traffic  service  centre.
Although  stated  in  the  media  repeatedly,  this  treaty ­
  is  not  an  agreement  about  the  boundary  in  the
Ems-Dollart  estuary.  It  explicitly  does  not  include  a
border  between  the  two  countries,  but  it  provides
legal  certainty  on  both  sides  with  a  pragmatic  solution. ­
  This  is  Important  for  further  Investments
and  the  administration  of  the  Ems-Dollart  estuary,
which  becomes  more  and  more  important  due  to
the  growing  Importance  of  the  coastal  seas  economically ­
  and  ecologically.
Role  of  hydrography
The  international  law,  especially  the  Law  of  Sea,
is  not  only  a  legal  issue  where  lawyers  and  politicians ­
  are  engaged  in.  The  example  described
above  shows  many  tasks  that  are  closely  related
to  hydrography.  One  prereguisite  is  of  course  the
provision  of  a  topography  of  the  sea-floor  and
the  wadden  sea.  Decisions  have  to  be  based  as
well  on  up-to-date  and  guality  assured  information ­
  of  the  coastline,  the  0  m  contour  line  and  the
talweg.  Description  of  estuaries  and  their  limits
have  to  be  based  on  scientific  research.  Calculations ­
  have  to  be  accomplished  regarding  coordinates ­
  and  transformations,  eguldlstance  lines  and
other  delimitations.  And  all  these  calculations
and  results  have  to  be  presented  In  digital  and
analogue  cartographic  products  and  in  presentations ­
  which  are  understandable  for  non-hydrographers.

The  hydrographers  probably  still  can  do  more
to  make  their  contributions  in  all  marine  fields  and
aspects  known  to  the  public  and  to  other  professions. ­
  They  should  be  more  self-confident  and
more  visible,  i
