5 GENERAL REPORT 
THE DEUTSCHES HYDROGRAPHISCHES INSTITUT (DHI) IN 1982 
The DHI is a Central Marine Navigation and Marine Environment Authority 
within the jurisdiction of the Federal Minister of Transport. It has the 
tasks 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 in 1982 comprised DM 13.9 million revenues and DM 65.9 
million expenditures. 
763 persons were employed in the DHI. 
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 
Research Vessel "Meteor", used jointly with the Deutsche Forschungsge 
meinschaft (German Research Association), undertook four research crui 
ses. In the chart portfolio, the first international chart of the medium 
and large scale series to be produced by the DHI was prepared for print 
ing. Two special chart series of the western Baltic Sea appeared for 
sports-boat navigation. 
In 1982, 6 Pilots, in new edition, appeared; they replaced 8 old vol 
umes and a British Pilot. Of the "Verzeichnis der Leuchtfeuer und Si 
gnalstellen" (List of Lights and Signal Positions) - which is comprised 
of 14 parts - 5 parts were published as new edition. By direction of the 
Federal Minister of Transport, the booklets "Sicherheit in der Sport 
schiffahrt im Seebereich" (Safety in sports-boat navigation on the seas) 
and "Verkehrsvorschriften für Wasserfahrzeuge in der Bundesrepublik 
Deutschland" (Navigation regulations for vessels in the Federeal Repub 
lic of Germany) were issued for the first time. 
The Survey and Research Ship "Komet" and the Survey Ship "SÜderoog" ran 
11,350 nautical miles of lines of sounding in the North Sea and the Bal 
tic Sea for the chart portfolio. The two Survey and Wreck Search Ships 
"Atair" and "Wega", both fitted out with light diving equipment, have 
checked 127 already known wrecks and positions at which submarine hin 
drances were suspected, and found 28 new wrecks. The Research Vessel 
"Gauß" carried out 16 cruises in the North Sea and the Baltic Sea for 
natural scientific investigations, type-approval tests, and equipment 
trials. 
As in the previous years, most of the oceanographic work was applied to 
the problems of the environment. Hereto, national and international co 
ordinated monitoring programmes in the North Sea and the Baltic sea were 
carried out - according to plan - by the chemical and radiological work 
ing groups: whereby, in addition to the noxious substances in seawater 
and in the sediments, the oxygen content in the German Bight was also 
regularly monitored. The weather-dependent critical oxygen deficiency in 
the near-bottom water, observed during the previous summer, did not re
