Buoys Provide Real-Time Surf Data

摘要

U.S. Navy beachmasters are using small, lightweight recording buoys to provide timely and accurate information for controlling boat lanes and tracking real time changes In surf conditions. The buoys, which log pitch, roll, and yaw to determine a wide variety of wave parameters, employ recently developed miniaturized accelerometers and magnetometers to measure wave characteristics that are entered into the Navy Standard Surf Model to calculate automatically surf information and the Modified Surf Index (MSI).
