The Norwegian Seismic Array (NORSAR)

Abstract

The operation, maintenance and research activities of the Norwegian Seismic Array (NORSAR) for the period 1 October 1980 to 31 March 1981 are described in this report. The detection processor operation has shown improvements as compared with previous reporting period with uptime percentage of 91.2 and 0.8 days meantime-between-failure as compared with 71.1% and 0.6 days. Still the special processing system (SPS) counts for most of the downtime. The MODCOMP is approaching the final implementation; presently the MODCOMP-to- IBM communication is performed on one subarray.
