Magnetotelluric Station Data from Minnesota, Wisconsin, and Upper Michigan

U.S. Geological Survey data consists of 176 wideband magnetotelluric stations collected from 2015 to 2019. It includes measured electric- and magnetic-field time series and estimated impedance and vertical-magnetic field transfer functions for station wup314. The dataset supports regional geologic investigations and mineral resource assessments.

Use Cases

• Model subsurface conductivity using estimated impedance and vertical-magnetic field transfer functions.
• Analyze measured electric- and magnetic-field time series for regional tectonic framework studies.
• Integrate station wup314 data with the full 176-station shapefile for 3D regional conductivity modeling.

Strengths

• Contains data from 176 distinct magnetotelluric measurement stations.
• Provides a multi-year time series collected from 2015 to 2019.
• Includes derived data products like estimated impedance and transfer functions alongside raw time series.

Limitations

• Data is provided only for a single station (wup314) within this specific publication.
• The primary data format is XML, which may require specialized parsing tools for analysis.
• Sample data and columnar structure are not explicitly documented, complicating initial exploration.
