The EM 2040 multibeam echo sounder is the first system to bring all the advanced features of deep water multibeams to the near bottom sounding environment. The basic EM 2040 has four units, a transmit transducer, a receive transducer, a processing unit, and a workstation.
For completeness, data input from a motion sensor and a positioning system is required, as is the sound speed profile of the water column between the transducers and the bottom. Sound speed at the transducer is an optional input. The transducers may be delivered mounted on a frame together with the motion sensor and a sound speed sensor, factory aligned for ease of mounting.
