On the investigation of vertical uncertainty of depth sounding in a shallow environment with muddy seabed: Preliminary results from a launch operation of a dual-frequency echosounder

Abstract: Hydrographic echosounder has been the standard instrument that provides a measure of water depths. In a muddy environment, this detection is not as straightforward as it seems; low gradient of acoustic impedance presence within the water-sediment interface resulting in vertical separation of liquid-solid boundary detected by different frequencies of depth sounding system. In this study, we investigate the depths measured by a dual-frequency hydrographic echosounder in a muddy environment, coupled with a simult… Show more
