Multibeam

Multibeam refers to a type of sonar or radar system that transmits and receives multiple beams simultaneously. This technique allows for significantly faster and more detailed mapping of underwater topography, seafloor features, and other surfaces. By sending out a wide fan of acoustic or electromagnetic energy, multibeam systems can cover a broader area with each sweep, providing high-resolution data crucial for navigation, resource exploration, environmental monitoring, and scientific research. The processed data generates 3D representations of the scanned environment.

Multibeam meaning with examples

• The research vessel employed a sophisticated multibeam sonar system to map the uncharted underwater canyons, revealing intricate details previously hidden from view. This mapping helped locate the sunken ship. The gathered data was used to create high-resolution bathymetric maps, crucial for understanding the geological processes shaping the ocean floor.
• Geologists used a multibeam radar system to survey a landslide-prone area. The system allowed them to monitor ground deformation and identify potential hazards, issuing early warnings to the local community. This ability helped to proactively implement preventative measures to secure the area.
• Coastal engineers utilized multibeam technology to assess erosion rates along the shoreline. The system created detailed elevation models to identify areas most susceptible to erosion and design effective coastal protection strategies. The analysis helped maintain the integrity of infrastructure near the coastline.
• Marine biologists employed multibeam sonar to study the distribution and abundance of marine life. The data enabled them to identify habitats favored by certain species and assess the impact of human activities on the underwater ecosystem, contributing to preservation efforts.
• Archaeologists used a multibeam system to search for ancient shipwrecks in the Mediterranean. The high-resolution scans identified anomalies on the seabed, which they then investigated using remotely operated vehicles (ROVs) to recover artifacts and document the ship's history.
