In the field of ocean hydrology, measuring the depth of the ocean is a fundamental task. Accurate measurement of ocean depths is essential for various activities such as navigation, marine research, and resource exploration. To achieve this, professionals in the industry rely on specialized instruments called sounders or echosounders. These devices emit sound waves that travel through the water and bounce back when they encounter the seabed, allowing for the calculation of water depth.
