NSF EarthScope MT-TA

Long-period magnetotelluric survey of approximately the northern two-thirds of the United States, carried out through a cooperative agreement between the Incorporated Research Institutions for Seismology (IRIS) and Oregon State University (OSU). Land permitting, data acquisition, quality control, and field processing were carried out in partnership with several different organizations over the course of this survey, including University of Utah, Zonge International Geophysical Services and Equipment, and Green Geophysics with project management and instrument/engineering support from IRIS/OSU and Chaytus Engineering, respectively. These efforts were funded by the National Science Foundation through the following EarthScope USArray-related awards to IRIS: EAR-0323309 "Collaborative Research: EarthScope-Acquisition, Construction, and Facility Management (USArray)", EAR-0323311 "Collaborative Research: EarthScope-Facility Operations and Maintenance (USArray)", EAR-0733069 "Collaborative Research: EarthScope Facility Operation and Maintenance (FY2008-FY2013) (USArray)", and EAR-1261681 "Seismological Facilities for the Advancement of Geoscience and EarthScope".
