given the highest priority by the Conference on Disarmament once the chemical weapons convention has been concluded. This effort should go hand in hand with a reduction of the role of nuclear weapons in military doctrines and defence structures. Norway will continue her active participation in the Group of Scientific Experts towards the establishment of a modern global network for the exchange of seismic data. The global seismological network proposed by this Group will be an essential part of a future verification system. Rapid advances in recent years in computer and data communications technology have opened up new possibilities for improving the effectiveness of such a global network. The main phase of the large-scale experiment on the global exchange of seismic data carried out by the Group of Scientific Experts is scheduled for the autumn of this year, and we are looking forward to the results. Norway is actively participating in this global data exchange experiment by providing data from her seismic array stations. The two regional arrays in Norway provide for excellent detection of small seismic events over a large portion of the northern hemisphere. A global network capable of providing a valuable analysis of weak seismic events is crucially important if we are to create confidence that a test ban is being complied with. This is the background for the Norwegian proposal that the global seismological network should as far as possible incorporate establishment of this type of array. CD/PV.548 6 (Mr, Bondevik, Norway ) The NORSAR organization is prepared to offer technical assistance to seismological institutions that are interested in establishing such arrays. This aspect of international research co-operation represents a serious effort on our part to contribute to the solution of the verification issues relevant 
**Analysis**
The text discusses the establishment of a global seismological network for the verification of a test ban, highlighting the importance of seismic data exchange and the role of Norway in this effort. The text also mentions the potential for improving the effectiveness of the network through advances in computer and data communications technology. This suggests that the category should be related to science and technology.
