    dct:description "This child item contains self-potential (SP) 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 SP method measures passive voltages in the subsurface using a high impedance voltmeter with one fixed electrode at a base station and one mobile electrode.  Strong self-potential anomalies have been associated with ore bodies and sharp redox fronts.  Data were collected with an Agilent U1252B multimeter with STELTH3 Ag-AgCl Model SRE-011-SPB porous pot electrodes.  Additional details are contained in the ‘readme.txt’ file within this directory." ;
