A depth sounder is a sophisticated device used to measure the depth of water beneath a vessel or over a specific area of the ocean floor. It utilizes sound waves and their reflection to determine the distance between the instrument and the seafloor. By analyzing the time it takes for the sound wave to travel to the seabed and back, scientists can accurately map the underwater topography, revealing the contours, ridges, valleys, and even submerged features like mountains and canyons.1 J! k# i2 @5 x1 ~; S
