A multibeam echosounder is a device that is mounted to the hull of a ship to determine the depth of water and the nature of the seabed. The system emits a broad acoustic pulse from under a ship and then records how long it takes the beams to return to the ship after bouncing off the sea floor.

Multibeam survey. Multi-beam surveys are used to gather detailed information about the features on the seabed by measuring multiple depths from a single transducer array at high resolution. The result is a highly accurate 3D picture of the sea floor. the need for multi-beam. It has many added advantages over the single beam surveys.

Schematic illustration of an MBES system and the ship's motions that
The multi-beam echo sounder (MBES) system is a high-tech product for application to modern marine surveys and is a complex system composed of multiple sensors. This chapter outlines the classification and the principles of an MBES and presents representative instruments and equipment along with marine survey workflows.

Given the lack of systematic research on bathymetric surveys with multi-beam sonar carried by autonomous underwater vehicles (AUVs) in unfamiliar waters, this paper proposes a method for multi-beam bathymetric surveys based on the constant-depth mode of AUVs, considering equipment safety, operational efficiency, and data quality.

Multibeam Bathymetry Surveys. Geoscience Australia collects bathymetry data in multiple ways, mostly commonly using multibeam surveys. During a bathymetric survey, a multibeam sonar system is mounted on the hull of a survey vessel. The sonar system sends out multiple soundwaves that bounce off the sea floor and return to the ship.
