Introduction of Automated Stationary MT Systems
Since 1996, Phoenix Geophysics Ltd. has installed a number of automated stationary MT systems in Japan, Canada, and India. The purposes and applications are: earthquake prediction research, geothermal reservoir monitoring, waste disposal site monitoring, provision of remote-reference time series data, continuous MT signal studies, stationary power source testing, and time-series data transfer testing. Because site conditions have varied widely, solutions to various problems have been developed, especially in dealing with continuous acquisition and high-volume data transfer, and reliable power sources for unmanned operation. The data-acquisition system originally employed was the V5, later upgraded to the SSMT2000 MTU-5S. The most recent equipment is System2000.net RXU-5 and V8 instruments. All instrumentation is synchronized by GPS time signals. This paper describes the various automated systems of past and present and demonstrates that automated stationary MT for a wide variety of applications is practical under virtually any conditions of geography, climate, and noise, with flexible options for power and data transfer.
