A camera on each side Pond Skater will be able to determine the direction of something of interest such as blue green algae. Blue green algae have a distinct color signature.  Cameras with a color enhancing program will bring out those colors, allowing a small aquatic rover to determine possible target areas to test.  By importing the Python Imaging Library (pillow), this signature will stand out. The images below show color enhancement can clearly show the iron content in the Virginia soil.
