Measurements of Harbor Features and Acoustic Properties

A series of data collections have been undertaken in Weymouth Fore River, Massachusetts, to characterize acoustic propagation in one enclosed basin. The goal of the work was to obtain data to describe the sound propagation in the basin, and to calibrate modeling systems for sound within ports and harbors. An ability to accurately model sound in these environments would inform future acoustic system design and deployment. Both monostatic and bistatic acoustic systems were used in the field work. The main data are from a (monostatic) bathymetric sonar, and a bistatic system composed of moored stationary receivers and mobile sound sources. The site, the systems used, data, and research findings are described here.
