Ground-based transient electromagnetic (TEM) data were acquired by the U.S. Geological Survey (USGS) in selected locations near Manistee National Forest, Michigan, to define the resistivity structure of the subsurface. Data were acquired using the ABEM WalkTEM system (Guideline Geo Ab, Sundbyberg, Sweden). TEM data were processed and numerically inverted to derive one-dimensional resistivity structure using SPIA (Aarhus Geosoftware, Aarhus, Denmark). This release includes raw and processed TEM data and resistivity models for each data location.
