Previews of 2004 Continuous Resistivity ProfilesThe table below contains previews of the 2004 resistivity profiles processed with the default water-resistivity value (no resistivity value entered in the DEP file). Both the EarthImager short JPEG image and the Matlab JPEG image of each processed file are presented. In addition, the trackline map below is a clickable map. By clicking on a line name, a new window will open with the processed images from that particular line segment. This includes the Matlab JPEG image as well as a reduced version of one of the EarthImager JPEG images. The beginning of each line is shown on the map with a triangle, which corresponds to the left side of the associated JPEG images. All versions of the processed JPEG images, including the longer version output from the EarthImager processing, can be downloaded from the Data Catalog page.

Preview of Profiles: Data collected May 17-20, 2004 (click individual images to see enlarged versions).
All profiles were created using the default water-resistivity value during processing (no value supplied to the DEP file). The white or black line in the image is the water depth as measured by the fathometer in meters. 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 the reds representing the higher resistivity values corresponding to fresher ground water. Each individual image has the scale maximized for the range of resistivity values in that data set. 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 the reds indicating higher resistivity values. In both versions, the X-axis represents distance along line in meters. The EarthImager version additionally has the latitude and longitude for start and end of line.
