An Integrated Calibration Method for Sounding Velocity Errors in ROV-Borne Multibeam Bathymetric Data (opens in new tab)

Accurate sound speed information is critical for bathymetry collected by multibeam echosounder systems (MBESs). However, achieving this remains challenging for high-resolution underwater topographic surveys performed by the remotely operated vehicle (ROV), leading to significant sounding velocity errors. To address this, we propose an integrated calibration method that sequentially corrects positioning inaccuracies, removes outlier beams, and performs sound speed inversion. First, ROV traject...
