Topside electronic systems for the multibeam side scan sonar system. At lower left are the topside processing units (TPUs) receiving real-time imagery and swath bathymetry data from the towfish. The four navigation system monitors located to the right track vessel and towfish position during survey operations. The closed circuit television at upper left monitors the winch containing the tow/transmission cable, which can be remotely controlled from this location. This control center was created from an empty space on the fish processing deck of the F/V Ocean Explorer. Image courtesy of Next Generation Tools 2001, NOAA-OER.
