Ground-based time-domain electromagnetic data and resistivity models near Manistee National Forest, Michigan, 2020

May 7, 2021

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. Also includes information on WalkTEM channel mapping for moment and receiver types USF files (49 files) - raw, unprocessed data files with naming convention [LONGDATE] and [_UNIQUEID] and [_STATIONID].usf, where LONGDATE (ex.20200916), UNIQUEID (ex. 230145_828), STATIONID (ex. Station1), MIT_TEM, AarhusInv_manual_TEM.txt - manual describing the TEM file format, TEM files (196 files) - processed data files with naming convention [MIT_TEM] and [_DATE] and [_MI] and [_SITE] and [_SIZE] and [_MOMENT] and [-RECEIVER].tem, where DATE (ex. 091620), SITE (ex. 756), SIZE (a='100m*100m', b='40m*40m'), MOMENT (ex. LM), RECEIVER (ex. RC005), Models, MIT_Model_Plots, Image files of model plots (49 files) - Images of model plots with naming convention [MIT_TEM] + [_DATE] + [_MI] + [_SITE].png, where DATE (ex. 091620), SITE (ex. 756), SIZE (a,b), TEM_model_data_dictionary.csv - Data dictionary describing all channels in tabulated model file, MIT_TEM_models.csv - tabulated model file. All channels are described in the model data dictionary MIT_TEM_2020_SoundingLocationsModels.gdb.zip - file geodatabase containing all sounding locations, model information, and has the model plots linked to each site.
