These measurements were cut off. 06/21/2023 (file - West_Northline_06212023_RES2DINV) Dipole-dipole array Spacing: 2.5 m number of spacings: 6 number of nvalues: 7 Location (0 m): N 40.92454, W 112.7622 Location (60 m): N 40.925, W 112.76241 06/21/2023 (file -West_Southline_06212023_RES2DINV) Dipole-dipole array Spacing: 2.5 m number of a spacings: 6 number of nvalues: 7 Location (0 m): N 40.91861, W 112.7625 Location (60 m): N40.91928, W 112.76274 06/29/2023 (file - West_Northline_Perpendicular_06292023_RES2DINV) Dipole-dipole array Spacing: 2.5 m number of a spacings: 6 number of nvalues: 7 Location (0 m): N 40.92502, W 112.76242 Location (60 m): N 40.925, W 112.76175 2. Relationship between files: NA 3. Additional related data collected that was not included in the current data package: NO 4. Are there multiple versions of the dataset? No -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: All data were collected using an ultra-miniRES electrical resistivity instrument from L&R instruments. An inline dipole-dipole configuration was used for each survey. 2. Methods for processing the data: Raw unprocessed data are in this repository. All data are text files in the RES2DINV format. 3. Instrument- or software-specific information needed to interpret the data: These data are recorded in RES2DINV format. This format includes 6 lines of header information: Line 1: survey name Line 2: electrode spacing (m) Line 3: type of array (3= inline dipole-dipole) Line 4: total number of measurements Line 5: type of x-location for data points (1= midpoint) Line 6: flag for Induced Polarization (IP) data (0 = none) The data follows the header and is x-location, a-spacing, n, apparent resistivity 4. Standards and calibration information, if appropriate: NA 5. Environmental/experimental conditions: NA 6. Describe any quality-assurance procedures performed on the data: NA 7. People involved with sample collection, processing, analysis and/or submission: NA
