The EarthScope Magnetotelluric Backbone station at Blacksburg, Virginia, began operating on April 6, 2008. This station, designated MBB05, is the second of seven permanent magnetotelluric stations to be installed in the continental US as part of EarthScope. The first MT station to come online is located in Soap Creek, Oregon. These instruments record naturally occurring electric and magnetic fields that will be integrated with other geophysical data to identify Earth's thermal structure and to study the significance of fluids in the crust.
A component of USArray, the magnetotelluric element – or EMScope – is managed by Oregon State University through a subaward from IRIS. The Blacksburg station was constructed in collaboration with Virginia Polytechnic Institute and State University. Professor Chester Weiss of Virginia Tech, along with Professor Adam Schultz from Oregon State University, lit up the new MT station. Initial magnetic field data recovered from the station are of high quality. Data from the MT systems are archived at the IRIS Data Management Center and are freely available to the scientific community and the public.
