Bathymetric maps are obtained using hydroacoustic (sonar) instrumentation and interfaced with differential global positioning system (DGPS) mounted on a boat. Hydroacoustics are utilized to detect the depth of a water body, sediment characteristics as well as the presence or absence, approximate abundance, distribution, size, and behavior of underwater biota. For additional details, see the user guide, protocols, and science design listed in the Documentation section in this data product's details webpage.
