Assessment of Electrical Resistivity Anomalies Caused by Fresh Water Discharge Across the Continental Shelf: Seeps off North Carolina

Abstract

To determine the impact that fresh water discharge across the continental shelf has on the electrical resistivity structure of bottom sediments and, by so doing, to use electrical measurements to constrain the regional hydrology and the exchange of continentally derived groundwater with the ocean. The strength and spatial distribution of resistivity anomalies caused by fresh water will be used to assess the likelihood of false target identification in mine counter measures, and the degree to which bottom conditions might be misclassified. The discharge of fresh water through permeable aquifer units may also be an important factor in slope failure.
