Description
Summary:This Semiannual Technical Summary describes the operation, maintenance and research activities at the Norwegian Seismic Array (NORSAR) , the Norwegian Regional Seismic Array (NORES), the Arctic Regional Seismic Array (ARCES) and the Spitsbergen Regional Array for the period 1 April to 30 September 1999. Statistics are also presented for additional seismic stations, which through cooperative agreements with institutions in the host countries provide continuous data to the NORSAR Data processing Center (NDPC). These stations comprise the Finnish Regional Seismic Array (FINES), the German Regional Seismic Array (GERESS), the Hagfors array in Sweden and the regional seismic array in Apatity, Russia. Beginning 1 January 1999, the responsibility for funding the operational activities of the seismic field systems and the Norwegian National Data Center (NDC) has been taken over by the Norwegian Government, with the understanding that the funding of IMS-related activities will gradually be arranged through the CTBTO/PTS. Research activities described in this report, as well as transmission of selected data to the United States NDC, are continuing to be funded by the United States Department of Defense. The NOA Detection Processing system has been operated throughout the period with an average uptime of 99.93%. A total of 2244 seismic events have been reported in the NOA monthly seismic bulletin for April through September 1999. The performance of the continuous alarm system and the data transfer to AFTAC has been satisfactory. Processing of requests for full NOA and regional array data on magnetic tapes has progressed according to established schedules. This Semiannual Report also presents statistics from operation of the Regional Monitoring System (RMS).
