The main purpose of this effort is to conduct research on how several regional seismic arrays can be employed together using the pooled seismic data in a simultaneous processing scheme. A site for deployment of a new array was identified in northern Norway and final approval for permission to deploy an array at this site was granted in early July 1987. This report describes the work associated with the different tasks of the site preparation and field system deployment, the arrangements for satellite transmission of data from the array site to NORSARs data processing center at Kjeller, and the installation of an interim system for acquiring and archiving data at Kjeller. A central terminal building was constructed to house the core of the field system. Approximately 30 km of both fiber optic and power cables were trenched to connect the seismometer sites with the central building. 25 seismometer surface vaults were built, and a borehole for the broadband seismometer was prepared at the center of the array. The system was ready for operation in early November. Keywords Beam forming.
