One technology oceanographers use to explore the ocean floor is multibeam sonar. This advanced sonar system emits multiple sonar beams in a fan shape to create a detailed 3D map of the seafloor topography. Multibeam sonar helps scientists to accurately study the features and structures of the ocean floor.
