Abstract:The acoustic properties such as the sound speed and the attenuation coefficient are important factors which influence the structure of the underwater field,underwater acoustic communication,performances of underwater acoustic equipments,detecting of objects on seafloor and so on.The work principle,structure and performance of the newly developed in situ sediment acoustic measurement system for shallow water are introduced,and its applications to measure the acoustic properties of seafloor sediment are reviewed.Several techniques that are needed for functional extension of this system for deep-sea survey are discussed.
Keywords:seafloor sediments  sound speed  sound attenuation coefficient  in situ measurement  deep-sea survey
