Marine acoustic surveying

Marine acoustic surveying uses sound waves to explore underwater environments, much like echolocation. Professionals deploy specially designed ships or equipment that emit sound signals into the water. These signals bounce off underwater features like the seabed, rocks, or objects, then return to sensors on the vessel. By analyzing the returning sound waves, scientists create detailed maps of the seafloor, identify underwater structures, or locate submerged hazards. This technique is essential for activities such as seabed mapping, laying underwater cables, or environmental assessments, providing accurate information about what lies beneath the water's surface without physical disturbance.
