WebThe benefits of multibeam echo sounders are that they map the seafloor with a fan of narrow acoustic beams, thus providing 100% coverage of the seafloor. The resulting seabed maps are more detailed than those obtained using single-beam technology. Producing maps using a KONGSBEG multibeam echosounder will improve survey efficiency by producing ... Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water (bathymetry). It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight, along with knowledge of the speed of sound in water, allows determining the distance between sonar and target.
