The  DHI  is  a  Central  Marine  Navigation  and  Marine  Environment  Authority
within  the  jurisdiction  of  the  Federal  Minister  of  Transport.  It  has  the
task  of  surveying  the  seas,  publishing  the  charts  and  nautical  books,
and  testing  the  nautical  equipment  used  on  board  ship.  Moreover,  it  has
to  promote  navigation  and  High  Seas  fisheries  by  natural  scientific  and
nautical-technical  research,  and  to  ensure  the  protection  of  the  marine
environment.
The  total  budget  comprised  DM  12.2  million  revenues  and  DM  67.7  million
expenditures.
The  Hydrographic  Services  (Tide,  Sea  Level  Forecast  and  Storm  Surge
Warning  Service,  Ice  Service,  Time  Service  for  Shipping,  Geomagnetic
Service)  again  fulfilled  their  tasks  for  the  safety  of  navigation.
The  DHI  published  5  Pilots  as  new  editions.  12  nautical  books  were
brought  up-to-date  by  means  of  Supplement.  In  addition,  the  booklets
"Bekanntmachung  der  Wasser-  und  Schiffahrtsdirektion  Nord  zur  Seeschiff ­
  ahrtstraßen-Ordnung"  and  "Winterbetonnung  der  Küstengewässer  der
Bundesrepublik  Deutschland",  the  "Nautisches  Jahrbuch  oder  Ephemeriden
und  Tafeln  für  das  Jahr  1985",  and  the  accompanying  booklets  to  the  4
sets  of  charts  for  sport-boats  on  the  North  Sea.  Of  the  "Verzeichnis  der
Leuchtfeuer  und  Signalstellen"  (List  of  Lights  and  Signal  Positions),  5
Parts  were  published  as  new  edition.  The  "Nautischer  Funkdienst"  and  the
"Sprechfunk  für  Küstenschiffahrt"  were  continued  by  12  Supplements  each.
The  Yacht  Radio  Services  "Nord-  und  Ostsee"  and  "Mittelmeer",  as  well  as
the  Table  "Wetter-  und  Warnfunk"  appeared  as  special  prints.  The  "Nachrichten ­
  für  Seefahrer"  (Notices  to  Mariners)  was  published  with  a  weekly
issue  of  3,200  copies.  By  direction  of  the  Federal  Minister  of  Transport, ­
  the  booklet  "Sicherheit  in  der  Sportschiffahrt  im  Seebereich"
(Safety  in  sport-boat  navigation  on  the  seas)  was  republished.  309  nautical ­
  reports,  which  came  in  from  voluntary  collaborators  were  evaluated. ­

The  chart  portfolio  published  21  new  charts,  108  new  editions,  161  updated ­
  reprints,  and  126  replacement  pages.
Of  the  14  international  charts  of  the  North  Sea,  which  are  to  be  processed ­
  by  the  DHI,  3  charts  were  produced  which  replace  the  national
charts  45,  46,  49,  87,  and  103.
The  chart  coverage  of  the  German  Baltic  Sea  and  North  Sea  coasts  with
sport-boat  charts  was  concluded  with  the  issue  of  the  chart  portfolio
no.  3013  "Nordfriesische  Inseln  mit  Helgoland".
In  response  to  the  suggestion  of  the  chart  users,  charts  of  the  Baltic
Sea  were  also  published  with  a  dense  geographical  graticule.
The  graphic  technique,  owing  to  the  further  modernisation  of  the  machines ­
  available,  was  also  able  to  cope  in  1984  with  the  technical-
