An automated, unmanned boat for shallow water use has been developed and field-tested to acquire hydrodynamics data using an acoustic Doppler current profiler (ADCP). After 91 hours and 453 km total distance surveyed, results demonstrate the numerous advantages this automated boat (A-Boat) possesses over manned survey vessels, such as the accuracy of repeating the planned route continuously over at least a tidal cycle to resolve tidal and subtidal current velocity profiles, the endurance, energy efficiency, ease of operation, and capability of coverage of shallow areas close to shore. We have applied the new A-Boat to several studies in Louisiana coastal waters. During one survey, we were able to map the detailed structures of a 300-m diameter small eddy at the Southwest Pass of Vermilion Bay. During another survey, we were able to repeat a transect 1500 times in 24 hours with a total of 125 km in distance. More modifications are being made for even better performance in more applications.


Dr. Li received a B.S. degree in atmospheric physics from the University of Science and Technology in China, a M.S. degree in physical oceanography from the Institute of Oceanology, Academy of Science (PRC), and a Ph.D. degree in oceanography from the University of Connecticut. Following completion of his Ph.D. degree, he spent four years as a Research Assistant Professor at CCPO. He then moved to Skidaway Institute of Oceanography and then to Louisiana State University, where he is currently an Associate Professor in the Department of Oceanography and Coastal Sciences. Dr. Li's research interests are in the areas of physical oceanography, transport, coastal and estuarine circulations, innovative observations, modeling, and weather-induced oceanographic and estuarine response and impact to the coast.
