Seafloor sediment acoustics is a burgeoning field of marine scientific research. In situ measurement technique key for investigating acoustic properties. Establishing correlation between in parameters and physical great significance advancing the theory seafloor acoustics. This study employed an system to measure sound speed attenuation various types sediment, such as sand, silty clay, clayey silt. The results showed that were strongly curvilinear correlated with properties, wet bulk...
Based on the data of acoustic and physical properties seafloor sediments obtained continental shelf area East China Sea (ECS), prediction equations sediment sound speed based single dual parameters were established, correlation with was discussed. The results show that (c) is strongly correlated water content (w), density (ρ), void ratio (e), mean grain size (Mz) median (Md), coefficient determination R2 empirical regression equation generally greater than 0.80, while compression (a) modulus...
Abstract The in situ acoustic measurement of seafloor sediment is an important technical means to obtain the parameters seafloor. time‐of‐flight method commonly used calculate sound speed sediment. Accurate identification signal feature points essential for determining travel time or difference signals. However, precise points, such as take‐off point first wave a signal, challenging. conventional manual inefficient and prone errors. development auto‐identification imperative accurately...
