Figure 5. Perspective views of three-dimensional (3D) surface of equal resistivity (7 ohm-meters) derived from a solid model created from the continuous resistivity profile (CRP) data in Dynamic Graphic's EarthVision software. Part A is a plan view map where the gray lines represent the CRP tracklines, the blue polygon represents the extent of the 3D model shown in part C, and the red box indicates the extent of the 3D model shown in part B. The color bar applies to both parts B and C, with resistivity values in ohm-meters. In each map along the northern part, small black symbols outlined in white represent offshore piezometer sampling locations. The white dashed lines in part B approximate paleochannel margins.
