![]() It is also extremely useful in examining environmental impacts. The Bathymetric survey has become quite an indispensable tool to industries such as the construction & oil industries especially as it concerns the laying of offshore pipes and facilitating offshore rigs. ![]() The energy received is then converted into electrical signals decoded to standardized marine nomenclature. The transducer is usually fixed on a ship or a boat, which sends sound energy to the seabed and then back to the transducer which acts as a receiver. This survey uses different kinds of acoustic sounding equipment to measure the depth of a body of water by making sound waves bounce from a transducer (which is a device that performs both functions of transmitting and receiving). A Bathymetric survey - also known as Hydrographic survey - involves mapping out the shape and how deep a terrain underwater is to describe the land that lies below. This implies that for an in-depth understanding of soil water content, and underwater topography, Bathymetry in the form of a Bathymetric survey is required. According to Wikipedia, "Bathymetry is the study of underwater depth of ocean floors or lake floors.” It is used to precisely ascertain the underwater topography of a body of water.
