A bathymetry survey was conducted near Zhou Shan Island, China (舟山岛) using the NORBIT WINGHEAD i80S multibeam sonar system equipped with STX (Steerable Transmit) technology. This state-of-the-art sonar was deployed specifically to scan and map the underwater bridge pillars, providing highly detailed bathymetric data. The combination of the WINGHEAD’s precision and the steerable transmit feature ensured thorough coverage even in challenging underwater environments.
