👉 Bathymetrical, or bathymetric, is a type of underwater surveying technique that involves measuring and mapping submerged objects, such as ships, submarines, and other structures at sea. This method allows for precise measurement of depth, which is essential for understanding the location and nature of underwater structures. Bathymetry is used in various fields, including navigation, hydrography, and water quality monitoring. It helps to identify areas where water currents are strongest or weakest, which can affect
