Acoustic Monitoring of Dredging-Related Suspended-Sediment Plumes

Abstract

This technical note presents the results of acoustic monitoring of suspended-sediment plumes during dredging operations. Monitoring was conducted in Mobile Bay, Alabama, during dredging by a hopper dredge and in Boston Harbor, Massachusetts, during dredging by a clamshell dredge. The results show how acoustic monitoring can be used with other instrumentation to provide valuable data characterizing the extent and dynamics of suspended-sediment plumes. Data presented in this technical note provide input for modeling of suspended-sediment plumes, evaluation of dredging methods, and environmental assessments.
