The Norwegian Seismic Array (NORSAR) Phase 3
Abstract
This report covers research and operations activities at the Norwegian Seismic Array (NORSAR) for the period 1 July - 30 September 1976. This is the last period where the full (22 subarray) array configuration is retained. Within the reporting period there have been 170 breaks in the otherwise continuous operation of the Detection Processor (DP). The uptime percentage is 96.6. Three operators left in the period, and the vacant positions were covered by substitutes and overtime by the other operators. The bulletin production under the full-sized NORSAR has now been discontinued and some statistics for the period 1971-1976 are given. Altogether about 70 000 processings have been completed by the Event Processor (EP) out of which approximately 36 000 have been accepted as true events. In the DP a number of modifications have been performed in order to adapt the system to an environment with only 7 subarrays. At subarray 01B it has been technically checked out that in the new array configuration it will be possible to send attenuated long period (LP) data in parallel to the ordinary data flow.
