Diana is one of two side-scan sonar systems on board Nautilus. It is used to create maps of the seafloor and to identify targets of interest that ROVs Hercules and Argus investigate in more detail. Diana is a side-scan sonar tow-fish that uses dual 300 and 600 kHz frequencies, with a range of approximately 200 meters on either side of the towfish.
