Sedimentological acoustics: an attempt to reduce the gap between acoustical modeling and sedimentoloogical survey
A major task in shallow water acoustics is to provide pertinent geoacoustical data. The purpose of the work is to evaluate the state of the art in this field, connecting in situ sedimentological measurement and acoustical modeling aspects. According to sonar systems frequency ranges and to the kind of needs, the measurement in terms of sedimentological data is different. Parametrisation requirements are investigated for both propagation and reverberation models. We propose to translate differently the survey knowledge, of a cal[brate zone, versus frequency to provide different parameter bottom sets to the users. We dtscuss the lack of avarlability of some of this parameters.
