The table below contains previews of the 50-m CRP data from Manhasset Bay processed using the average measured water resistivity value (WRES) of 0.35 ohm-m. Both the EarthImager 2D 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 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. The line names represent the original line names at time of data collection.

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 resistivity 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. 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 extremely short lines that did not require the roll-along processing, the temperature plot is not generated during processing and the x-axis units are distance along line in meters. Additionally, L54F1 is so short that the MATLAB image title and x-axis label are truncated.
