PHI Research Programme 
2.DHI 
Natural chemical constituents 
Investigation of reliability 
and precision of continuous oxygen 
readings 
Investigation of the chemical 
composition of sediments and 
suspended matter in the North 
Sea and the Baltic Sea 
Measurement network 
Installation and operation 
of an automatic oceanographic 
measuring station on the 
unmanned lightships; 
ELBE I, DEUTSCHE BUCHT, 
and TW EMS as well as on the 
Research Platform "NORDSEE" 
Remote sensing: 
Draft of a concept for utilization 
of remote sensing data in the DHI since 1987 
Currents: 
Summary investigation of currents 
in the whole North Sea area based 
upon current measurements and 
remote sensing data. (Verification 
of DHI North Sea models.) 
In future continuous registrations should reveal 
critical oxygen occurrences in good time. 
Transmission of the following parameters to the DHI 
via satellite. 
Water temperature in different depths 
conductivity in different depths 
oxygen contents of the water column 
radioactivity of the water column 
(The data are partly used for monitoring 
purpose) 
Comparison between measurement data and model 
results.
