Description
Summary:SeisMs.NORSAR, a seismic monitoring system that is part of a joint effort by Norway and the United States is developed to relay real-time data streams generated from the ARCESS array located at Finmark (Karasjok) to the NORSAR acquisition site located at Kjeller, Norway. SeisMS. NORSAR consists of a communications hardware/software subsystem called a Communications Interface Module (CIM) and a near-real-time software subsystem for automated acquisition and processing of the seismic data. One CIM located at ARCESS receives the real-time array (hub) and high frequency (HF) data streams, multiplexes them and retransmits the stream by satellite to the NORSAR sites. At NORSAR, a receiving CIM demultiplexes the data, buffers it if necessary, and relays the hub and HF data streams to a DCP board in a Sun Workstation. Data acquisition software running in the workstation, diverts each data stream onto a circular buffet disk loop, from which all or selected portions of the raw data can be reformatted to conform to a CSS database and archived to tape or written to a CSS database and archived to tape or written to a CSS data base on disk. This report includes information on CIM reference, CIM maintenance, using the data acquisition software, and manual (man) page for user commands and required input file formats.
