This data set consists of 59 wideband magnetotelluric (MT) stations collected by the U.S. Geological Survey in July and August of 2020 as part of a 1-year project funded by the Energy Resources Program of the U.S. Geological Survey to demonstrate full crustal control on geothermal systems in the Great Basin. Each station had 5 components, 3 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles. Data were collected for an average of 18 hours on a repeating schedule of alternating sampling rates of 256 samples/second for 7 hours and 50 minutes and 4096 samples/second for 10 minutes. The schedules were set such that each station was recording the same schedule to allow for remote reference processing. Data were processed with a bounded-influence robust remote reference processing scheme (BIRRP v5.2.1, Chave and Thomson, 2004). Data quality is good for periods of 0.007 - 2048 with some noise in the higher periods and less robust estimates at the longer periods. Files included in this publication include measured electric- and magnetic-field time series (.h5 files) as well as estimated impedance and vertical-magnetic field transfer functions (.edi files). An image of the MT response is supplied (.png file) where the impedance tensor is plotted on the to two panels, the induction vectors in the middle panel (up is geographic North), and the phase tensor in the bottom panel (up is geographic North). The real induction vectors point towards strong conductors. Phase tensor ellipses align in the direction of electrical current flow and warmer color represents the subsurface becoming more conductive and cooler colors more resistive.
