CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface. CSAMT involves transmitting a current at various frequencies in one location, and measuring resistivity differences between electrodes spaced along a receiver line several kilometers from the transmitter. Data were collected using a GGT-30 transmitter and GDP32-II receiver (Zonge international. Inc.). Data processing and inversions were carried out using Zonge International, Inc. software. As a processing step, measured resistivity values must be \"inverted\", or converted to 2-d vertical resistivity profiles. 2D smooth-model inversion figures: JPG files created by  Zonge International, Inc. software, depicting the modeled inversion data can be downloaded from this page.\nIn addition raw data, station location data, and inversion data files are useful for reprocessing the inversions and testing alternative inversion schemes. They are included in the .zip file on this page or   can be downloaded individually from the child pages linked below.\nRaw Data: Text files output by the data-collection instrument (GDP32-II, Zonge International, Inc.); averaged values are used in the inversion. These data may be useful for testing alternative inversion schemes.\nStation Data: Text files with the receiver locations for each line. data were collected using a handheld GPS.\nInversion Data: Text files of inverted resistivity values, starting model values, and corresponding x, y, z coordinates These files allow the user to recreate the inversions provided in the accompanying .JPG files\nVersion 2.0 of this data release includes 2 km of additional data on Line 1.", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://doi.org/10.5066/P9QF9PFR", "description": "Landing page for access to the data", "format": "XML", "mediaType": "application/http", "title": "Digital Data"}, {"@type": "dcat:Distribution", "description": "The metadata original format", "downloadURL": "https://data.usgs.gov/datacatalog/metadata/USGS.5f31f31682cee144fb2ead0c.xml", "format": "XML", "mediaType": "text/xml", "title": "Original Metadata"}], "identifier": "http://datainventory.doi.gov/id/dataset/USGS_5f31f31682cee144fb2ead0c", "keyword": ["Arizona Water Science Center", "Kane County", "Red Knoll", "USGS:5f31f31682cee144fb2ead0c", "Utah", "electromagnetic surveying", "geophysics", "geoscientificInformation", "hydrogeology"], "modified": "2022-07-21T00:00:00Z", "publisher": {"@type": "org:Organization", "name": "U.S. Geological Survey"}, "spatial": "-112.72000, 37.12640, -112.62000, 37.17400", "theme": ["geospatial"], "title": "Controlled source audio-frequency magnetotellurics (CSAMT) data from the Sevier fault near Red Knoll, Kane County, Utah (ver. 2.0, July 2022)"}
