This report details the results of a study aimed at trialling three acoustic seabed mapping systems in Plymouth Sound, to determine their effectiveness in identifying and spatially discriminating marine benthic biotopes. A sidescan sonar, a swath-sounding interferometer and a normal beam acoustic ground discrimination system were compared over an established calibration area. The area was surveyed by each system on more than one occasion.
