upwelling water off the Northwest African coast — which belongs to the most 
richly populated fishing places in the world — the internationally co-ordinated 
long term CINECA*) Programme was concluded with oceanographical, marine 
chemical, and biological investigations. The geological and geophy 
sical research work (magnetism, gravimetry, and seismology) was 
concentrated upon the area around Iceland, the region of the Azores, and the 
Northwest African continental margin; they served — amongst other things — 
for the preparation of, and supplement to, the world-wide drilling programme 
IPOD (International Phase of Ocean Drilling) in which the Federal Republic of 
Germany is participating. The work in summer 1977 was concerned with the 
structure of the Earth's crust in the region of the Reykjanes Ridge and off the 
Norwegian coast; in autumn, on the Northwest African continental margin, geo- 
scientific investigations concerning the genesis of the Atlantic Ocean were 
continued. 
Besides its routine task of collecting, preparing, and supplying German oceano 
graphic data, the Deutsches Ozeanographisches Datenzentrum 
— which is attached to the DHI for organizational reasons — took part in the 
data processing for international joint experiments, e. g, FLEX '76, IGOSS**) 
Marine Pollution (Petroleum) Monitoring Pilot Project. 
In both 1976 and 1977, at 23 positions in the German Bight and at 18 stations in 
the western Baltic Sea, samples of water, suspended matter, and the bottom 
were taken and investigated for their content of various groups of noxi 
ous substances. In accordance with legal duties ***) the DHI makes deci 
sions concerning applications for permission to dump wastes and monitors the 
compliance with the internationally determined conditions for same. The DHI 
participates intensively in the international efforts against pollution of the seas; 
for example, in Working Groups of the International Council for the Explora 
tion of the Sea (ICES) and the Inter-Governmental Oceanographic Commission 
(IOC), as well as within the framework of the Helsinki Convention. 
In autumn 1976, the DHI took part in an Aircraft Remote Sensing 
Programme sponsored by the BMFT****), by which the German Bight was 
investigated to see in how far oceanographical parameters — such as surface 
temperature, wave movement, chemical pollution, content of suspended matter 
in the water, etc. — could be measured by remote sensing. The ground truth 
measurements necessary therefor were carried out on board SRV "Gauß". 
The charts of the North Sea surface temperature, which — with the support of 
the German Scientific Commission for Marine Research — are issued weekly, 
received increasing interest. In addition to the automatic permanent mea 
surement station, which has been in existence for years at Kiel Light
