Ground penetrating radar (GPR) data collected in a mine-impacted wetland near Silverton, Colorado in September 2019
This child item contains ground penetrating radar (GPR) data collected over a small alpine wetland between Mogul Mine and Cement Creek located near Silverton, Colorado. Mine-impacted water is transported to Cement Creek via surface channels and groundwater through this wetland. The GPR method transmits radar pulses into the ground and measures the returned amplitude from these pulses over time. Variations in subsurface electromagnetic (EM) properties (dielectric permittivity, electrical conductivity, and magnetic susceptibility) affect the timing and amplitude of returned radar energy. For example, variation in water or mineral content are physical properties that often influence the EM properties that are observed with GPR. For these deployments a MALA GX monitor and 450 MHz HDR antennas were used and measurements were made over several transects within the wetland. Additional details are contained in the ‘readme.txt’ files within each zip data directory.
