Streamer electrical resistivity survey on Panama Canal – hydrogeophysics

Image of horizontal streamer electrical resistivity slice of survey on Panama Canal – hydrogeophysics

Horizontal slice taken at 21m below canal water level of electrical resistivity from all data with the Gamboa Sub-reach (turns H–J). Surface geologic information adapted from Stewart et al. (1980) and modified per information in Kirby et al. (2008) and Retallack and Kirby (2007). Boreholes are overlain on the resistivity to discern hard rock from loose sediment.
