A Novel Technique Using Side Scanning Sonar to Map Benthic Habitat of Medium to Large River Systems
A need exists within the natural resource community for an inexpensive and rapid technique for mapping and quantifying benthic habitat features of navigable river systems. Habitat mapping and assessment are critical components of research and management of aquatic fauna and the systems they inhabit. Unlike more expensive side scanning sonar units, the Humminbird side imaging system employs a transducer that can be mounted directly to the transom of a small boat thus enabling the survey of streams that include shallow, rocky areas. Our field experience with the Humminbird 981c has...
