    • Bulk electrical conductivity data

    Metadata Updated: January 20, 2026

    Tracking changes in bulk electrical conductivity (EC) during tracer tests in saturated sediments allows for direct observation of both mobile and less-mobile pore space exchange dynamics. Electrode arrays made up of four stainless steel rods (insulated with the exception of exposed 0.5 cm tips) were installed vertically at depths of interest and apparent electrical resistivity data (the inverse of bulk EC) were collected using a Wenner configuration with an AGI SuperSting R8 meter. The Bulk EC data are described and listed within the files below. Controlled, downward flow experiments were conducted in Dual-domain porosity apparatus (DDPA). Downward flow rates ranged from 1.2 to 1.4 m/d in DDPA1 and at 1 m/d, 3 m/d, 5 m/d, 0.9 m/d as described in the publication: Briggs, M.A., Day-Lewis, F.D., Dehkordy, F.M.P., Hampton, T., Zarnetske, J.P., Singha, K., Harvey, J.W. and Lane, J.W., 2018, Direct observations of hydrologic exchange occurring with less-mobile porosity and the development of anoxic microzones in sandy lakebed sediments, Water Resources Research, DOI:10.1029/2018WR022823.
