Abstract An innovative solution is proposed to address the issue of abnormal bottom tracking data in acoustic Doppler velocity profiling.Explore the possibility of using depth data from a single beam deep-sea depth sounder to replace bottom tracking data from an acoustic Doppler velocity profiler,in order to eliminate anomalous data located below seabed depth.By strictly controlling the quality and accurately interpolating the water depth data of the single beam depth sounder,the correspondence between the acoustic Doppler velocity profiler and the depth sounder data at time nodes is achieved.Then,the depth data of the depth sounder is used to replace the depth data tracked by the acoustic Doppler velocity profiler,effectively identifying and eliminating the "false velocity" outliers of the acoustic Doppler velocity profiler below the seabed depth.Through experimental verification,this method can effectively solve the data processing problem when the bottom tracking of the acoustic Doppler velocity profiler is abnormal,and improve the data quality control effect.
