Abstract: In a number of sonar studies, bathymetric information is used to correct and
visualise amplitude data. This work proposes a method which combines amplitude features
(describing backscattering strength and sonar texture) with bathymetric features (indicating
seafloor variability) for sonar classification. Features are selected per window (of user
defined size) and areas around grab samples in a survey are used for training. The
importance of different features is investigated in this study, and highlighted by feature
