The table below contains previews of the CRP data processed using the average measured water resistivity value (WRES) of 1.0345 ohm-m. Both the EarthImager 2D JPEG image and the MATLAB JPEG image of each processed file are presented. In addition, the trackline maps below are "clickable" maps. Because of the tight survey lines in the area outlined by the gray box, a "zoomed" in map is supplied. By clicking on a line name in either map, a new window will open with the processed images from that particular line segment. This new window will contain the MATLAB JPEG image as well as a reduced version of the EarthImager 2D JPEG image (short version). The beginning of each line is marked with a triangle on the map. The left side of the associated JPEG image represents the beginning of the line and corresponds to the triangle on the map. Julian day 135 is May 15, 2007; Julian day 136 is May 16, 2007; and Julian day 137 is May 17, 2007. Line names represent the original line names created in the field.

Preview of Profiles - click individual images to see full-size JPEG images of the profile. For the EarthImager 2D versions, the long version of the profile is available. All of the profiles are available for download from the Data Catalog page.

In the EarthImager 2D version, the white line in the image represents the water depth as measured by the fathometer. In the MATLAB-generated JPEG images, the water depth is represented by a black line. The JPEG images resulting from the EarthImager 2D processing were saved with the default color scale generated by the software. This color scale ranges from blues to reds with reds representing the higher resistivity values which correspond to fresher (less saline) groundwater. Each individual image has the scale maximized for the range of resistivity values in that dataset. The MATLAB versions of the JPEG images use a common color scale for all the files to facilitate profile comparison. For these images, the polarity of the color scheme is the same as that of the EarthImager 2D JPEGs in that the colors range from blue to red with reds representing higher resistivity values. In the MATLAB version, the X-axis represents distance along line in meters. The EarthImager 2D version X-axis units are latitude and longitude (position) along line. On the second day of surveying, the temperature information was available at times and included with the resistivity profile when available. The temperature information was available for all of the lines on the third day of surveying. On extremely short lines that did not require the roll-along processing, the temperature plot is not generated during processing.
