Figure 7. This photo shows a view of the sonar lab on the U.S. EPA Ocean Survey Vessel Bold. The side-scan sonar towfish is remotely controlled from the lab. Using a joy stick, the towfish can be raised and lowered to optimal distances above the sea floor. Sonar data is streamed into the lab in real time to computer monitors. Screens also display conditions on the deck, winches, and movement of people. MGS file photo July 3, 2012 by S. M. Dickson.
