Multi-Beam Sonar is a technology used to map the underwater environment. It emits multiple sound waves simultaneously, allowing it to cover a wide area of the seafloor. This method provides detailed information about the shape and features of underwater landscapes, such as shipwrecks and coral reefs. The system works by sending out sound pulses and measuring the time it takes for the echoes to return. By analyzing these echoes, scientists can create high-resolution images of the ocean floor. This technology is essential for various applications, including marine research, fishing, and navigation.
