Resistivity differences can be attributed to subsurface geology (conductive vs less conductive layers) and hydrogeologic conditions with fresh water exhibiting high resistivity and saline conditions showing low resistivity. The RES2DINV format is a common format used by researchers who work with resistivity data. To provide the linearized raw continuous resistivity profile (CRP)data collected on in the Corsica River Estuary by the AGI SuperSting system in the RES2DINV format. More information on the field work can be accessed from the Woods Hole Coastal and Marine Science Center Field Activity webpage: Better understanding of the style, locations, and rates of groundwater discharge could lead to improved models and mitigation strategies for estuarine nutrient over-enrichment in the Corsica River Estuary, and other similar settings. Techniques used included continuous resistivity profiling (CRP), piezometer sampling, seepage meter measurements, and collection of a radon tracer time series. Geological Survey (USGS) science team conducted field operations in the estuary in April and May 2007.

Resource managers are concerned about nutrients that are entering the estuary via submarine groundwater discharge from this primarily agricultural watershed that may be contributing to eutrophication, harmful algal blooms, and fish kills. Submarine groundwater discharge (SGD) into Maryland's Corsica River Estuary was investigated as part of a larger study to determine the importance of nutrient delivery to Chesapeake Bay via this pathway.
