The table below contains previews of the 50-m streamer CRP data processed using the average measured water resistivity value (WRES) of 0.32 ohm-m. The EarthImager 2D JPEG and MATLAB JPEG images of each processed file are presented. In addition, the trackline maps below are "clickable" maps. By clicking on a line name, a new window will open with the processed images from that particular line segment. This new window will contain a reduced version of the EarthImager 2D JPEG image (short version) as well as the MATLAB JPEG image. 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.

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 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 corresponding 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 indicating higher resistivity values corresponding to fresher (less saline) groundwater. 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 EarthImager processing, and the x-axis units are distance along line in meters. Additionally, on these short lines the MATLAB image titles and x-axis labels are often truncated.
