Heiland Lecture: Dr. Adam Schultz

Heland Lecture Adam Schultz


“The 3-D Magnetotelluric Array Revolution – Insights into the role of hydrous and
magmatic fluids in continental evolution and natural hazards at convergent margins, along hotspot traces, at the passive margin and in the continental interior”

Dr. Adam Schultz, Professor of Geophysics, Oregon State University & Chief Scientist, Pacific Northwest National Laboratory


Substantial advances in 3-D inversion of electromagnetic induction data over the past decade-and-a-half, coupled with sustained support for large-scale 3-D magnetotelluric (MT) array data acquisition efforts have produced a remarkable legacy of MT data and derived data products, and of an emerging canon of 3-D views of crust and mantle electrical conductivity structure. For the past thirteen years, Oregon State University has been the lead institution for the NSF EarthScope MT Program, responsible for acquiring data from approximately 1000 long-period MT stations covering (to-date) on a 70-km interstation grid spanning more than 60% of the territory of the Conterminous US. Also under NSF EarthScope, MARGINS/GEOPRISMS and US Department of Energy Support, OSU and its collaborators have acquired high-resolution, targeted MT array data along the Cascadia margin (both onshore and offshore), in the southern Washington Cascades volcanic arc, at Yellowstone supervolcano, and a 4-D dataset including MT data from an enhanced geothermal stimulation effort at Newberry volcano in central Oregon. We have also acquired a unique, combined MT-ionospheric data set from more than two months of synchronous observations over a wide area in the interior of Alaska. In today’s Heiland Lecture, key insights into the role of fluids in the evolution of each of these differing tectonic settings will be presented, drawn from 3-D inverse models produced by researchers from various institutions that are involved in each of these projects. The serendipitous discovery that knowledge of the 3-D electrical structure of the crust and mantle plays an important role in assessing the vulnerability of the electric power grid to the effects of space weather and to risks from electromagnetic pulse (EMP) events will also be introduced.
