Multibeam Echosounder / Multibeam Sonar
Multibeam echosounders (multibeam sonar) are advanced acoustic imaging systems deployed for seafloor mapping and bathymetric surveying. Multibeam echosounders capture high-resolution 3D images of the seafloor, with precise measurements and detailed information about underwater topology.
Multibeam echosounders (MBES), also known as multibeam sonar, is a type of sonar which emits a fan-shaped array to map the seafloor. Multibeam echosounders, unlike single-beam echosounders, emit multiple beams simultaneously, covering a large area of the seafloor.
The ability to provide detailed, high-resolution three-dimensional mapping data over wide areas, makes them essential in many marine and underwater applications, from navigation and construction to environmental monitoring and scientific research.

Subsea Mapping and Charting
Multibeam echosounders are used for hydrographic surveys to create accurate maps of the seafloor. These maps are crucial for navigation, and tasks such as laying submarine cables and pipeline routing.
Habitat Mapping
High-resolution data is used to help in mapping and monitoring underwater habitats, such as coral reefs. This information is key for environmental conservation and management.
Archaeological Surveys
Underwater archaeologists deploy echosounders to discover and map shipwrecks, sunken cities, and other submerged cultural heritage sites.
Offshore Oil and Gas
The oil and gas industry employs multibeam sonars for site surveys before drilling, pipeline inspection, and monitoring the seabed.
Dredging Operations
MBES help in planning and monitoring dredging operations by providing detailed images of the areas to be dredged, ensuring precise and efficient removal of sediment.
Scientific Research
Marine scientists use multibeam echosounders to study oceanography, geology, and marine biology. This helps in understanding seafloor spreading and marine ecosystems.
