Magnetotelluric data from Minnesota, Wisconsin, and Upper Michigan, 2015-2019, station pen009

This dataset consists of 176 wideband magnetotelluric (MT) stations collected from 2015-2019 across parts of Minnesota, Wisconsin and the Upper Peninsula of Michigan. The U.S. Geological Survey (USGS) acquired these data as part of regional investigations into the geologic and tectonic framework of the area and to support mineral resource investigations. These data have been used to generate a 3D regional conductivity model of the area. Files included in this publication include measured electric- and magnetic-field time series as well as estimated impedance and vertical-magnetic field transfer functions. The data included here are for MT station pen009 in the Penokean Orogeny survey region. A shapefile with station information for all stations in this dataset is available at https://doi.org/10.5066/P9G2Y71H.
