Instrument Description
Echosounder, Hydrographic Multibeam
Multibeam bathymetric echosounders acoustically map the seafloor. Typically mounted below a ship or ROV, they transmit a narrow fan of acoustic beams from a transducer. These beams are reflected by the seafloor contours and received by the instrument. The return signal angle and travel time are used to calculate the depth and position for points on the seafloor. Motion and heading sensors are used to compensate for the relative movement of the instrument.
Capabilities and system components vary between manufacturers and models.
