USArray, in conjunction with EMSOC (ElectroMagnetic Studies of the Continent), is installing magnetotelluric (MT) stations as part of EarthScope. The MT Facility consists of both permanent and portable elements that measure naturally occurring electric and magnetic fields. The backbone component consists of seven permanent MT stations installed across the United States as a reference network. These data will be integrated with other geophysical data to identify Earth's thermal structure and study the significance of fluids in the crust.

Twenty transportable MT systems are being acquired to complement the seven permanent MT stations. The transportable MT instruments are being used for deployments of approximately one-month duration on a nominal 70-km grid spacing for imaging of crustal and lithospheric conductivity structure in areas of special interest as proposed by the MT community and approved by NSF. For more information on MT station deployment, visit EMScope.
