The Deutsches Hydrographisches Institut (PHI) in 1983 
113 
(EMC), founded in 1978, has been completed. Owing to the increasing num 
ber of electronic pieces of equipment on the bridges of sea-going ships, 
the tests for EMC gain in importance. 
In 1983, the DHI issued 20 permits for the carrying out of research ac- 
ion in accordance with the Bundesberggesetz (Federal Mining Law). In 
accordance with the Rohe-See-Einbringungsgesetz (High Seas Dumping Law) 
9 permits for the incineration of wastes on the High Seas were extended. 
The permits for the disposal of wastes with the incineration ship "Mat 
thias II" were cancelled, because the incineration system no longer ful 
filled the regulations. The dumping of processed sewage sludges in the 
High Seas was stopped in spring. 
The DHI was involved in 38 preliminary legal proceedings concerning 
detected pollution by oil, 5 fines were imposed. 
The Library, which also looks after the interests of the Maritime Trans 
port Division of the Federal Minister of Transport and the Seewetteramt 
of the German Weather Service, increased its stock to 113,000 volumes.
